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 motor will turn at 72 rpm. This speed can be varied by varying the frequency, although the majority of applications simply use gearing or a belt- or chain-drive program to achieve the desired load speed.

We provide a comprehensive selection of AC synchronous engine products which includes continuous torque, high torque and hybrid options to meet a wide variety of program 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 swiftness within 5 to 25 milliseconds. They can also stop within 5 examples of rotation and reverse similarly rapidly.

We offer two agricultural Chain groups 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 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 source. We also offer hazardous duty AC synchronous motors, qualified to UL Course I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX standards.
