Parts
The important parts of a wet grinder are :

– Motor
– grinding stone
– container
– pulley
– belt
– frame and stand
Motor: The motor used in the wet grinders is usually the capacitor start-induction motor (Fig 2 & 3). It has two
windings. Both the starting and running windings are energised to start the motor, when the 70 to 80 % of the
rated speed is reached, the starting winding is switched off by the centrifugal switching system. The motor then
operates only on running winding.
