General Purpose Slip-Ring Induction Motors
The catalogue covers slip-ring induction motors called also wound rotor induction motors that are applied to start a high inertia load
or a load that requires a very high starting torque across the full speed range. These motors can be also applied in drives where
limited speed regulation is required.
Our motors are designed for long life and reliable operation.
FEATURES AND BENEFITS
The slip-ring motor is an induction machine where the rotor
comprises a set of coils that are terminated in slip rings to which
external resistance can be connected. The stator is the same as
is used with a standard squirrel cage motor.
By changing the resistance connected to the rotor circuit, the
speed/current and speed/torque curves can be altered.
By correctly selecting the resistors used in the secondary
resistance or slip ring starter, the motor is able to produce
maximum torque at a relatively low current from zero speed to
full speed. A secondary use of the slip ring motor, is to provide a
means of speed control. Because the torque curve of the motor
is effectively modified by the resistance connected to the rotor
circuit, the speed of the motor can be altered. Increasing the
value of resistance on the rotor circuit will move the speed of
maximum torque down.
