#100120 - motor specs
Responding to: Russell Bull's previous message

No insult intended, but when you asked whether to switch the active or neutral tends to suggest your skill in electronic design is probably at the level of selecting a suitable relay.

Firstly many thanks for a detail reply, I would not call myself an expert in electronics either, I am basically a mechanical engineer but in this particular job I have to use electronics as a tool to achieve the goal. I hope this forum does not mind people like me who do not have brilliant knowledge in electronics. I am working hard to learn and I hope that this forum could also help me to become more competent in electronics.

At no point have you told us anything about the motor. I'm assuming something that draws a few amps - if its a little fan motor - then use a triac!

its a single phase AC motor, power = 0.75KW. It has to drive fairly large load and the current do tends to go high. the normal specs of motor are

50Hz 220-240V AC
power = 0.75KW, 0.50HP
Current = 2.9A

I guess this clarifies things more
