Synchronous motors are often used in applications where precise speed is critical to the application. Shaded pole (asynchronous) motors offer higher levels of output power than synchronous motors however speed will vary under load.
The most important step lies in the accurate definition of the work that you require the motor and gearbox to perform. The selection of a suitable motor and gearbox can only be made if the torque and speed can be defined. Of these two parameters, torque is probably the most difficult to identify - please contact us if you need help.

Hurst permanent magnet synchronous motors are reversible permanent-split capacitor motors identical in construction to the Hurst stepping motors. The 60 Hz can-stack motors operate at synchronous speeds of 300 and 600 RPM. High quality gearing is available for the can-stack motors. The ceramic rotor magnet material provides a relatively high flux resulting in a good torque to size ratio at moderate cost. In addition the permanent magnet construction provides inherent dynamic braking and low rotor speed for quiet operation and rapid acceleration. The disadvantages of permanent magnet motors are a limited ability to accelerate inertial loads and a high sensivity to the parameters of voltage and phasing capacitor. The first of these problems may be minimized by gearing or in some cases flexible couplings. The sensitivity to voltage and phasing capacitor directly affects the directional reliability of both starting and running under load. In Hurst motor designs directional reliability is a primary consideration and is assured when motors are operated with the recommended capacitor within a voltage range of 10% of nominal.

ABM SINOCHRON®Motors are permanently excited synchronous motors, e.g. rotor speed matches the rotational frequency of the revolving stator field. In comparison to common induction motors they feature outstanding efficiency, high power density and compact dimensions and to conventional synchronous motors no encoder feedback for inverter or servo control operation is required.
SINOCHRON®Motor design features almost perfect sinusoidal distribution of the magnetic flux. With this unique property SINOCHRON®Motors are perfectly suited for sensorless operation and offer an economical alternative to expensive servo drives. Concurrently they boast better dynamic behaviour and efficiency than induction motors.
Simple rotor design, with internally located high performance magnets, allow for more economical manufacturing of SINOCHRON®Motors than servo motors without major impact on power density and control behaviour.
Sinusoidal magnetic flux minimizes troublesome cogging and improves rotational behaviour and noise emissions over conventional permanent magnet motors.
