AC motor - Wikipedia. 2018-7-22 · Operating principles. The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.

When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less.

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.

converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting. A squirrel-cage motor or a synchronous motor started direct on line without any help of a frequency converter normally cannot produce sufficient starting torque.
The slip of the motor (the ratio of the difference between the synchronous speed and the rotor speed to the synchronous speed) is zero. Asynchronous motors operate at speeds lower than the ...
