AC synchronous motors will be the workhorses of industry. With synchronous engine technology, speed is directly proportional to AC input frequency – for instance, at 120 Vac, 60 Hz, an AC synchronous engine will turn at 72 rpm. This speed could be varied by various the frequency, although the majority of applications simply make use of gearing or a belt- or chain-drive system to attain the desired load speed.
We provide a comprehensive selection of AC synchronous engine products including continuous torque, high torque and hybrid options to meet an array of app requirements. Our synchronous motors offer many advantages, like the ability to start Transmission Chain within 1-1/2 cycles of the used frequency and reach full synchronous swiftness within 5 to 25 milliseconds. They are able to also stop within 5 examples 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 available in each size. Resistor-capacitor kits are available for operating two-stage synchronous motors from a single-phase power supply. We also provide hazardous duty AC synchronous motors, qualified to UL Class I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX criteria.
