AC synchronous Leaf Chain motors will be the workhorses of market. With synchronous electric motor technology, speed is straight proportional to AC insight frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous engine 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 program to achieve the desired load speed.

We provide a comprehensive range of AC synchronous engine products which includes continuous torque, high torque and hybrid choices to meet an array of software requirements. Our synchronous motors provide many advantages, like the ability to start within 1-1/2 cycles of the used frequency and reach full synchronous velocity within 5 to 25 milliseconds. They can 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 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 source. We also provide 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 requirements.
