AC Synchronous Stepper Motors
AC Synchronous Motors from Haydon Kerk
AC Synchronous Motors from Haydon Kerk, are stepping motors that are run on AC (Alternating Current). With synchronous motor technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply use gearing or a belt- or chain-drive system to achieve the desired load speed. Other motor technologies (Ie. induction, DC, servo and step motors) either need gear reducers, or electronic drives to match the fixed speed of synchronous motors.
AC Synchronous from Kollmorgen
Kollmorgen offers two families 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-phase synchronous motors from a single-phase power source. We also offer hazardous duty AC synchronous motors, certified to UL Class I, Division 1, Group D; UL Class 1, Division 2, Groups E, F and G; and ATEX standards.
ST and SN Series synchronous motors provide high performance in three frame sizes, NEMA 23, 34 and 42 (60, 90 and 110 mm). Resistor-capacitor kits are also available.
These high-torque synchronous motors are available in NEMA 23, 34 and 42 frame sizes (60, 90 and 110 mm), providing up to 1,500 oz-in (1,059 N-cm) of torque.
Providing torque up to 1,500 oz-in (1,059 N-cm), these synchronous motors are available in UL Listed versions suitable for use in Class I, Division 1, Group D hazardous locations. Frame sizes are NEMA 42 and 66 (110 mm and 170 mm).
AC Synchronous Linear Actuator Configurations
AC Synchronous Motors are also available in AC Synchronous Linear Actuator configurations from Haydon Kerk. In the case of a linear actuator the linear speed produced is dependent on the resolution per step of the motor. For example, if 60 hertz is supplied to a .001-in/step motor the resulting speed is .240-in per second (240 steps per second times .001-in/step). Many of the Haydon Kerk™ stepping motors are available as 300 or 600 RPM AC synchronous motors.
