AC sychronous motors

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

We provide a comprehensive selection of AC synchronous engine products including continuous torque, high torque and hybrid choices to meet a wide selection of program requirements. Our synchronous motors offer many advantages, like the ability to begin within 1-1/2 cycles of the applied frequency and reach complete synchronous acceleration within 5 to 25 milliseconds. They can also stop within 5 levels of rotation and reverse equally rapidly.

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