AC sychronous motors

AC synchronous motors will be the workhorses of industry. With synchronous engine 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 could be varied by various the frequency, although the majority of applications simply use gearing or a belt- or chain-drive system to achieve the desired load speed.

We offer a comprehensive range of AC synchronous electric motor products including continuous torque, high torque and hybrid choices to meet a wide selection of program requirements. Our synchronous motors provide many advantages, including the ability to start within 1-1/2 cycles of the used frequency and reach complete synchronous quickness within 5 to 25 milliseconds. They can also stop within 5 degrees of rotation and reverse similarly Transmission Chain rapidly.

We offer two groups of AC synchronous motors in the ST/SN Series and KS/SS Series. High performance motors in these series can be found in NEMA 23, 34 and 42 body sizes, with two- and three-phase models obtainable in each size. Resistor-capacitor kits are for sale to operating two-phase synchronous motors from a single-phase power resource. 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.
