Worksheet time: 8mins
The motor that does not have a commutator is the
Repulsion Motor
Induction Motor
DC shunt motor
AC series motor
The principle of operation of induction motor is based on
Faraday's law
Flemming's right hand rule
Lemuel's Law
Ohm's law
The rotor of an induction motor gets its power from
Magnetic attraction
Magnetic Induction
Magnetic repulsion
All of the above
The rotor speed of an induction motor is
Different as the synchronous speed
The same as the synchronous speed
Faster than the synchronous speed
Slower than the synchronous speed
The induction motor differs from the synchronous motor is that it (a) is induced to the rotor.
Squirrel cage induction motor differs from the (a) type in that it has no slip rings.
Name this part of the induction motor
If the no load speed of a squirrel cage induction motor connected to a three phase 60 cycle supply is 740 rpm. The motor has
2 poles
8 poles
4 poles
9 poles
Squirrel cage induction motor has a (a) starting torque
In an induction motor the rotor runs at speed which is always (a) than the speed of the stator field
