AC synchronous motors are the workhorses of sector. With synchronous electric motor technology, speed is directly proportional to AC insight frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by different the frequency, although the majority of applications simply make use of gearing or a belt- or chain-drive system to achieve the desired load speed.
We offer a comprehensive selection of AC synchronous engine products including continuous torque, high torque and hybrid options to meet an array of application requirements. Our synchronous motors offer 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 are able to also stop within 5 levels 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 framework sizes, with two- and three-phase models available in each size. Resistor-capacitor kits are for sale to operating two-stage synchronous motors from a Leaf Chain single-phase power supply. We also provide 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.
