SSR and two speed AC motor
SSR and two speed AC motor
(OP)
I am using an SSR to start/stop a two speed 230VAC motor from a computer. The motor has 3 wires (neutral, low speed and high speed). When the high speed wire is connected to the SSR it works as it should. When the low speed wire is connected the motor will not stop. The motor draws around 50mA which is in the load current range of the SSR. What is the cause for this and is there an easy fix? I guess it has to do with zero crossing, or....

Easy fix... find a thyristor-based SSR designed for inductive duty.

If we learn from our mistakes I'm getting a great education!
