AC sychronous motors

AC synchronous motors are the workhorses of industry. With synchronous engine technology, speed is straight proportional to AC insight frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous electric motor will turn at 72 rpm. This speed could be varied by different the frequency, although the majority of applications simply use gearing or a belt- or chain-drive system to achieve the desired load speed.

We provide a comprehensive selection of AC synchronous electric motor products which includes continuous torque, high Auto Chain torque and hybrid options to meet an array of software requirements. Our synchronous motors offer many advantages, like the ability to begin within 1-1/2 cycles of the applied frequency and reach complete synchronous swiftness 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. Powerful 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 resource. We also provide hazardous duty AC synchronous motors, accredited to UL Course I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX specifications.
