Product Description:
The PMB33E-00101-03 is a brushless servomotor produced by Pacific Scientific as part of the PMB Brushless Servomotors series. Designed for precision control in industrial automation environments, the unit couples to a matched drive to deliver commanded torque and speed so axes can follow programmable motion profiles with repeatable positioning over frequent start-stop cycles. The motor is intended for automated stations that demand responsive starts, stops, and short settling times during repetitive duty. Its brush-free electromagnetic design reduces maintenance while supplying quick response for indexing tables, pick-and-place heads, and other servo-controlled machinery that must repeatedly position loads with tight accuracy.
Mechanical interface begins with the NEMA Size 34 frame, allowing the housing to mount directly on equipment that already supports standard 3.4-inch square motors. Internally, a stack length multiple of 3 increases active lamination height, raising continuous torque without changing the face size. When powered from a 240 Vac bus, the winding draws a nominal stall current of 7.4 ARMS, a figure used to verify amplifier current capacity. Rotor position feedback is supplied by a three-phase Hall sensor, which allows six-step commutation or can serve as an index for higher-resolution encoders. Power and feedback conductors leave the stator as flying leads with AMP connectors, simplifying field wiring when cabinet space is limited and rear clearance around the motor is tight.
Application flexibility is expanded by a factory-installed shaft seal and PTC thermistor package. The seal helps limit lubricant migration at the shaft exit, while the thermistor reports winding temperature to the drive for thermal protection during sustained load. The output shaft is machined with a flat, providing a positive surface for set-screw couplings and reducing part count compared with keyed assemblies. This combination suits compact motion axes that require simple coupling hardware and monitored motor temperature during continuous cycling.
