AC synchronous motors will be the workhorses of sector. With synchronous motor technology, speed is directly proportional to AC insight frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed could be Auto Chain varied by varying the frequency, although many applications simply make use of gearing or a belt- or chain-drive system to achieve the desired load speed.

We offer a comprehensive range of AC synchronous engine products including continuous torque, high torque and hybrid options to meet an array of app requirements. Our synchronous motors offer many advantages, including the ability to start within 1-1/2 cycles of the applied frequency and reach complete synchronous rate within 5 to 25 milliseconds. They are able to also stop within 5 degrees of rotation and reverse similarly rapidly.

We offer two groups 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 available in each size. Resistor-capacitor kits are available for operating two-stage synchronous motors from a single-phase power supply. We also offer hazardous duty AC synchronous motors, accredited to UL Class I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX specifications.
