AC synchronous motors are the workhorses of market. With synchronous motor technology, speed is straight proportional to AC input frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous electric motor 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 program to attain the desired load speed.

We provide a comprehensive range of AC synchronous electric motor products which includes continuous torque, high torque and hybrid choices to meet a wide range of program requirements. Our synchronous motors provide many advantages, like the ability to begin within 1-1/2 cycles of the applied frequency and reach full synchronous rate within 5 to 25 milliseconds. They can also stop within 5 examples of rotation and reverse equally rapidly.

We offer two families of AC synchronous motors in the ST/SN Drive Chain Series and KS/SS Series. High performance motors in these series can be found in NEMA 23, 34 and 42 frame sizes, with two- and three-phase models available in each size. Resistor-capacitor kits are available for operating two-phase synchronous motors from a single-phase power resource. We also offer hazardous duty AC synchronous motors, authorized to UL Class I, Division 1, Group D; UL Class 1, Division 2, Groups Electronic, F and G; and ATEX specifications.
