Motor wiring

Motor wiring

Motor wiring

(OP)
I have a single phase 220/240 motor complete with gearbox/magnetic brake. Motor terminal are marked A1, A2, Z1 and Z2.

From what I am able to trace A1 & A2 each have a wire that goes to the motor and brake.
Z1 & Z2 also seem to dissapear somewhere to the motor while Z2 has a starting capacitor in series.

Not being very familiar with electric motors I was wondering how to wire up the existing four core plus earth cable to enable this motor to work?

The reduction gearbox has a 1425/12 ratio, I believe that the unit was originally used for a stairlift.

The manufacturer was Normand Electrical Co. Ltd.

Many thanks in anticipation.

RE: Motor wiring

Looks like your motor was made for reversing. A1 & Z1 go together as does A2 & Z2. Apply the power and see how she runs. Swapping the Z leads should reverse the motor.

Thanks for that Steve, you are spot on.

I now need to control the motor which is continuous rated at 3.4amps.

From what I can make out all I need is a 'Crossover Switch'. I think I can do this using a 250v, 10amp, 3pole resistive relay and two non latching push buttons for safety.

If you know of a simpler method I would appreciate your thoughts.

Many thanks

Suggestion: The motor control should meet the Authority Having Jurisdiction for safety.
