synchronous motor, alternatingcurrent electric motor designed to run at a speed that is directly proportional to the frequency of the electric power source. Typically, a synchronous motor has a stator with a winding similar to that of an induction motor. Its rotor produces a constant magnetic field, either from a direct current in its windings or by use of permanent magnets.

The ball mill is a cylindrical form of container that is driven by a toothed circular gear by couple of gears present in the gear box. The gear box is a setup intended for making the power transmission from the electric motor to the ball mill. During this stage the gear box plays a crucial role in terms of controlling speed and torque.
