Characteristics
Higher efficiency in the same frame size





Three-phase distributed winding
in stator (identical to conventional
induction motors).
Rotor with aluminum cage and
internal high-energy permanent
magnets.
Starts and accelerates directly
connected to the mains, as an
induction motor.
Operates at synchronous speed
(invariant with load).
Same frame size of induction
motor, for same power.

Advantages







Synchronous operation  no I²R losses in the
aluminum cage.
Higher efficiency compared to Premium Efficiency
induction motors  high energy savings.
Low bearing temperature  longer life and less
maintenance.
No sensors  high reliability.
Interchangeability with existing installations.
No need for special protection relays.
Multi-motor operation  several motors in
synchronism fed by the same inverter.
4
Limitations

Limited synchronization capability with inertia  not
suitable for all applications.

Care must be taken in the assembly and disassembly
of the motor, due to magnets in the rotor, and special
tools may be necessary for the IEC frame 132.
5
Development tools (software)

SPEED software package (analytical and numerical analysis). WEG is
member of the SPEED Consortium – SPEED Lab – Glasgow
University.
6
Development tools (software)

FLUX2D software (numerical analysis) from CEDRAT – France.

PM x LSPM


PM (inverter-fed PM motor):
- Have no cage in the rotor;
- Needs a FOC (field oriented control) inverter and information
about the rotor position at any instant (either from an encoder
or a sensorless algorithm);
- Cannot be directly connected to the mains, even for nonvariable speed applications;
LSPM (line-start PM motor):
- Have a cage in the rotor;
- Can be directly connected to the mains;
- Do not need an inverter to run in a non-variable speed
application;
- For variable-speed applications, can be driven by an inverter
with scalar control algorithm.
