In order to start a slip ring motor, the accelerating torque has to be sufficiently higher than the resisting torque. Higher is the inertia, higher has to be the accelerating torque, otherwise the start will be very long and the motor can be damaged by the heating. If the motor is started directly, without starter: The current absorbed by the ...
3. Separator: A converter-fed dc motor/variable speed slip ring induction motor can be employed. The speed is controlled between 150-300 rpm to adjust the fineness of the cement product. The speed range is 1:10 by armature voltage control at constant torque. 4.
Slip ring motors or also called wound rotor motors are the heart in a lot of drive applications in the high power range. They are most commonly used in the raw material industry like mining of ore and minerals or in the binders industry like cement, limestone and gypsum in diverse technologies of crushers, roller presses and mills but also in large fans, pumps and conveyors.
