M2L Topology
Power is fed to the M2L inverter from a standard, easily sourced isolation transformer, which
can be placed in a remote or outdoor location. All M2L drive systems are compliant with
IEEE519-1992 input harmonic current requirements through the use of an 18-pulse input
transformer (standard).

Long lead filters should be considered on applications where the cable distance between the motor and the variable frequency drive exceeds 300 feet.
Long lead filters protect the motor from high DV / DT.

Dynamic Brake Resistors
and Brake Modules
Dynamic brake resistors and modules are used to address over voltage conditions with drives. Over voltage trips occur when the DC bus in
the drive increases to the over voltage trip level. This increase in voltage occurs when the mechanical energy in the motor is converted into
regenerative electrical energy, which is transferred back into the drive (the motor acts like a generator).
Regeneration occurs when:
• The deceleration time is too quick
• The load has high inertia and keeps rotating after the drive output power has decreased
below that of the load (Ex: fly wheels, large fans)
• The load is an over hauling load, cyclical or periodic (Ex: pump jack, punch press)
• When the motor suddenly becomes unloaded (Ex: lumber mill saw applications)
Regeneration can occur on an occasional basis
or periodically (cyclical) depending on the
type of load. A dynamic brake module and
resistor are required to be added to the drive
to dissipate this excess power. The module
and resistor must be sized correctly
depending on the application.
Contact Benshaw for assistance with sizing brake resistors and brake modules.

Prepackaged Solid State Starters
MVRXE Series
Emergency ATL Bypass, Severe Duty, Load Break
Fusible Disconnect
Product Highlights:
The Benshaw Medium Voltage Starter is a microprocessor controlled solid state
reduced voltage starter for three phase induction motors. The starter provides
a closed-loop current ramp for smooth stepless motor acceleration. Supplied
in a free standing enclosure.
Enclosures are available in NEMA 12 or NEMA 3R configurations. The medium voltage
enclosure consists of two distinct compartments. The medium voltage or power pole
section is located in the main body of the enclosure, whereas the low voltage section
containing the control logic is located behind the door as an isolated compartment.
Each starter is supplied with a load break isolation switch, Class "R" motor fuses, inline
vacuum contactor, solid state power poles and a vacuum bypass contactor, which is
used to bypass the SCR power poles once the motor is up to full speed.
The logic control incorporates the MX3 computer that has all the circuitry required
to drive the power semiconductors, which are located in the power section.
MVRXE starters provide solid state reduced voltage starting for normal operation
and full voltage emergency back-up starting, with complete electronic motor
protection at the flip of a switch.
This unique redundant design is ideal for critical applications where downtime
is extremely disruptive and cannot be tolerated.
MX3 solid state controls provide precise digital starting and stopping,
motor protection, metering, diagnostics and communications, standard.

Line Reactors
For 2.4 kV solid state starters, line reactors are not required.
For 5 kV / 7.2 kV solid state starters, line reactors are required when the supply source transformer is greater than 20 MVA (5% Impedance) or the
motor lead wiring length is 1,000 feet or greater. For systems with custom motor control lineups and power factor correction capacitors, consult
the factory.
For 13.8 kV starters, consult factory for the requirement of line reactors.
The line reactors are available in two options. If the unit is required to be UL approved, the reactors must be installed on the top of the unit
(reactors are shipped loose and must be installed by customer). This will add to the height of the enclosure. For units not requiring UL approval,
the reactors may be installed inside the enclosure. The inside mounting requires the enclosure width to increase to accommodate the added
reactor. The price includes the hardware necessary to mount and wire the reactors and the increased size of the enclosure where required.
A de-tuning reactor may be required to protect the power system from the adverse interaction of capacitors and non-linear loads. To ensure
the power factor correction device is properly applied, consult a qualified engineer or provide your single line electrical diagrams to Benshaw
for evaluation.

* Consult factory for higher HP rating.
** Consult factory for higher voltage rating.
Product Highlights:
Wound rotor motors are typically used in applications requiring high starting torques, a limited
number of operating speeds or a stepped acceleration to achieve a soft start. Typical existing
applications utilize an electromechanical starter on the stator and introduce multiple stages of
resistance in the rotor via contactor arrangements to achieve a soft ramp.
With the RediStart MX3, wound rotor control is greatly simplified. The RediStart consists of
two major sections: 1) A solid-state stator control, and 2) secondary resistors into the rotor
circuit from a separate 3-phase resistor bank. This achieves the high torque required by the
application—with low inrush—while providing a smooth stepless start. This greatly reduces
the maintenance cost of the typical electromechanical control.
Single Step Rotor Control: The solid-state starter is wired to the motor stator circuit, and
the resistor and shorting contactor are wired to the motor rotor circuit. The solid state starter
accelerates the motor to slip speed (determined by the resistance value) and then activates
the contactor to short the rotor. This allows the motor to accelerate to full speed.
Multiple Step Rotor Circuit: WR RVSS series starters can be supplied with multiple stages of
rotor resistor and contactor combinations. This arrangement may be necessary for multiple step
starting of extremely high inertia loads, or for continuous operation at multiple speeds. Multiple
steps of rotor resistance can be coordinated to achieve this.
Variable Speed Control: Variable speed control of wound rotor motors can be accomplished
with the RediStart series control. By maintaining full output voltage of the control going to
the stator of the wound rotor motor, and varying the resistance in the rotor, variable speed
is accomplished.
Resistors must be rated for continuous duty operations. Variable loads (pumps and fans) only.

Product Highlights:
The sync motor functions as an induction motor during start up. Once the motor
approaches full synchronous speed, the Redistart DC exciter induces a constant
polarity to the rotor causing the motor to lock into sync. Because the rotor’s field
is constant and separately excited there is no slip required to produce torque,
as with an induction motor. This allows the motor to run at synchronous speed.
The Benshaw synchronous package consists of a solid state starter portion connected
to the stator and an SEP (synchronous excitation package) that is connected to the
rotor section in conjunction with a discharge resistor. This SEP is supplied for brush
type and brushless exciters.
Synchronous Benefits:
The RediStart series solid state starter provides reduced voltage stepless acceleration
and automatic synchronization of three phase AC synchronous motors. Synchronous
motors are utilized for a number of reasons. They are used in applications that require
precise motor speed, they are used to obtain greater efficiencies, and they are used
for facility power factor correction.
2.4, 3.3, 4.1 and 6.6 kV**
Since synchronous motors can be operated at leading power factor, they are used
to correct a facility’s lagging power factor created by all the other induction motors
being operated.
Exciter Ratings:
This correction reduces the penalty a customer pays the utility company for creating
poor power factor.

Wound Rotor Starters
RATINGS
Horsepower:
20–1500 HP
Overload:
500% for 30 seconds
125% continuous
Starting Torque:
0–100%
Voltage:
200–1000 VAC
Typical Resistance Steps:
1-2
Product Highlights:
Wound rotor motors are typically used in applications requiring high starting torques,
a limited number of operating speeds, or a stepped acceleration to achieve a soft
start. Typical existing applications utilize an electromechanical starter on the stator
and introduce multiple stages of resistance in the rotor via contactor arrangements
to achieve a soft ramp.
With the RediStart MX3, wound rotor control is greatly simplified. The RediStart
consists of two major sections: 1) A solid-state stator control, and 2) secondary
resistors into the rotor circuit from a separate 3-phase resistor bank. This achieves
the high torque required by the application—with low inrush—while providing a
smooth stepless start. This greatly reduces the maintenance cost of the typical
electromechanical control.
Single Step Rotor Control: The solid-state starter is wired to the motor stator circuit,
and the resistor and shorting contactor are wired to the motor rotor circuit. The solid
state starter accelerates the motor to slip speed (determined by the resistance value)
and then activates the contactor to short the rotor. This allows the motor to accelerate
to full speed.
Multiple Step Rotor Circuit: WR RVSS series starters can be supplied with multiple
stages of rotor resistor and contactor combinations. This arrangement may be
necessary for multiple step starting of extremely high inertia loads, or for continuous
operation at multiple speeds. Multiple steps of rotor resistance can be coordinated
to achieve this.
Variable Speed Control: Variable speed control of wound rotor motors can be
accomplished with the RediStart series control. By maintaining full output voltage of
the control going to the stator of the wound rotor motor, and varying the resistance
in the rotor, variable speed is accomplished.
Resistors must be rated for continuous duty operations. Variable loads (pumps and
fans) only.
Key Advantages:
• Benshaw MX3 technology
• Modbus capable
• Single step rotor control
• Configurable output relays
• Modular power stack design
• Multistep and variable speed
for ease of maintenance
• Integral bypass contactor design

Includes discharge resistor
and synchronous excitation
package for brush type and
brushless motor.
Exciter Ratings:
125–250 VDC
30–120 A*
Product Highlights:
The sync motor functions as an induction motor during start up. Once the motor
approaches full synchronous speed, the Redistart DC exciter induces a constant
polarity to the rotor causing the motor to lock into sync. Because the rotor’s field
is constant and separately excited, there is no slip required to produce torque,
as with an induction motor. This allows the motor to run at synchronous speed.
The Benshaw synchronous package consists of a solid state starter portion connected
to the stator and an SEP (synchronous excitation package) that is connected to the
rotor section in conjunction with a discharge resistor. This SEP is supplied for brush
type and brushless exciters.
Synchronous Benefits:
The RediStart series solid state starter provides reduced voltage stepless acceleration
and automatic synchronization of three phase AC synchronous motors. Synchronous
motors are utilized for a number of reasons. They are used in applications that require
precise motor speed, they are used to obtain greater efficiencies and they are used
for facility power factor correction.
Since synchronous motors can be operated at leading power factor, they are used
to correct a facility’s lagging power factor created by all the other induction motors
being operated.
This correction reduces the penalty a customer pays the utility company for creating
poor power factor.
Key Advantages:
• Benshaw synchronous technology
• Modbus communication
• Solid state synchronous rotor control
• Configurable output relays
• Modular power stack design
• Reduced maintenance
for ease of maintenance
• Integral bypass contactor design
• Advanced synchronous
