Ac Voltage Actuator/reversing Induction Motor

[RMI]

Hi,

 

I need to control some AC voltage actuators that use reversing induction motors. The manufacturer's literature warns that there are high voltage spikes when first fired to open and close. The manufacturer will not recommend a relay to use for this. All they will tell me is it should have at least a 10 amp contact rating with at least a 240vac rating but the higher voltage rating the better. Has anyone controlled this type of valve actuator and what did you use?

 

Thanks,

yes, that is how you would reverse an induction motor. But the details will depend upon they type of motor, i.e. 1 phase or 3 phase, then if 1 phase, there are several types.

It is a single phase motor.

OK, but realize that no all 1 phase motors can be reversed. Do they give you a wiring diagram that shows the necessary connection differences between CW and CCW rotation? If not, it may not be possible. If so, do you have a nameplate on the motor that provides the electrical information on it, such as voltage, full load current, locked rotor current, code letter etc.?

 

 

Give me something to work with here...
