AC synchronous motors are the workhorses of market. With synchronous engine technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous Stainless Steel Chain electric 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 achieve the desired load speed.
We provide a comprehensive range of AC synchronous electric motor products which includes continuous torque, high torque and hybrid options to meet a wide range of program requirements. Our synchronous motors offer many advantages, including the ability to begin within 1-1/2 cycles of the used frequency and reach full synchronous rate within 5 to 25 milliseconds. They can also stop within 5 levels of rotation and reverse equally 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 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 supply. We also offer hazardous duty AC synchronous motors, qualified to UL Class I, Division 1, Group D; UL Class 1, Division 2, Groups Electronic, F and G; and ATEX specifications.
