AC synchronous motors will be the workhorses of industry. With synchronous motor technology, speed is directly proportional to AC input frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous electric motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply make use of gearing or a belt- or chain-drive program to achieve the desired load speed.

We offer a comprehensive selection of AC synchronous motor 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 swiftness within 5 to 25 milliseconds. They are able to also stop within 5 examples of rotation and Transmission Chain reverse similarly rapidly.

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