what is the difference between synchronous motor and
induction motor?
Answer Posted / dnp.electrical
Synchronous motor runs at synchronous speed only while
induction motor runs at speed lower than the synchronous
speed. 3 phase Synchronous motor needs 3 phase AC voltage at
its stator terminals and DC supply at its field winding /
rotor winding while 3 phase induction motor only needs 3
phase rated AC voltage to operate. In synchronous motor,
rotor field gets locked with stator flux and rotor rotates
at the synchronous speed i.e. at the speed of the rotating
magnetic field.

what is R Core Transformer. how it differs from normal transformers. dont search in net and post the answer.
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
