I want to design a circuit to control the speed of the motor of a single phase induction motor of ceiling fan into three level( max tourque -2800 rpm ). I want to do it by controlling voltage, in that case how should I do it?
I know that one way is to provide several connecting points or taps on the motor winding and another one is by using light dimmer type circuit. The dimmer varies the effective voltage by chopping the waveform with a triac.
Which one is more efficient and cost effective?
