rotating speed

asynchronous speed

synchronous speed

slip speed

star delta starter

DOL starter

Auto transformer starter

Rotor resistance starter

overload relay

no volt coil

back-up fuses

protective earth conductor

the starting torque is very low

the motor takes five to seven times of its full load current

it will pick up very high speed

it will run in the reverse direction
