The AS range. Six models, one speed.
Reversible synchronous motors for any drive that must start, stop and reverse on command. All models run at 60 RPM on single phase 220/230 V, 50 Hz. Available as ALL-STEP or FINE-STEP.
Choose by torque.
Pick the torque your drive needs. We'll show the model, its current and power, and a link to its datasheet.

Not sure which model?
Tell us what the motor will drive, the load, and how often it starts and reverses. We'll recommend a model and the matching capacitor and resistor.
Matched parts for the reversing circuit.
Each motor reverses through a simple capacitor and resistor circuit. We supply matched Deki run capacitors and STEAD wirewound resistors, so the motor, capacitor and resistor arrive as one tested set.
Datasheets for every model.
One datasheet per model, in the same format for ALL-STEP and FINE-STEP. PDF download, with no form to fill in.
