AC synchronous motors are the workhorses of industry. With synchronous motor technology, speed is straight proportional to AC insight frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous engine will turn at 72 rpm. This speed could be varied by various the frequency, although many applications simply use gearing or a belt- or chain-drive system to attain the desired load speed.

We offer a comprehensive selection of AC synchronous engine products including continuous torque, high torque and hybrid choices to meet a wide selection of software requirements. Our synchronous motors provide many advantages, like the ability to start within 1-1/2 cycles of the applied frequency and reach complete synchronous speed within 5 to 25 milliseconds. They are able to also stop within 5 examples of rotation and reverse Auto Chain equally rapidly.

We offer two families of AC synchronous motors in the ST/SN Series and KS/SS Series. Powerful motors in these series are offered in NEMA 23, 34 and 42 framework sizes, with two- and three-phase models available in each size. Resistor-capacitor kits are for sale to operating two-stage synchronous motors from a single-phase power resource. We also provide hazardous duty AC synchronous motors, certified to UL Course I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX standards.
