Product Description:

The PMB33E-00200-00 brushless servomotor is produced by Pacific Scientific within the PMB Brushless Servomotors series. It is installed in automated assemblies to transform drive-controller output into accurately regulated rotary motion. This supports position or speed control for material-handling axes, indexing tables, and coordinated multi-axis gantries where repeatable motion is required. In closed-loop systems, the motor responds to amplifier commands with controlled acceleration and stable running behavior during changes in load.

This motor occupies the NEMA Size 34 frame class, which uses a face-mount pattern and shaft height common in compact machinery. During locked-rotor conditions, it draws a nominal stall current of 7.4 ARMS at 240 VAC, which helps with servo amplifier sizing and thermal planning. Rotor position is returned to the drive by a resolver, allowing sine-cosine feedback over wide temperature and vibration ranges. This feedback method suits servo systems that operate near vibration sources or in areas where electrical noise can affect sensitive control signals. The output shaft is machined with a flat, which simplifies torque transmission with simple hub clamping rather than keyed couplings. Power, feedback, and ground conductors emerge as flying leads with MS connectors, allowing direct termination into harnesses while retaining the sealing of military-style circular connectors and supporting compact cable routing.

A stack length multiple of 3 increases active copper and iron within the frame so higher continuous torque can be achieved without changing external dimensions. The unit is supplied as a standard motor, which means that no special winding or flange modifications have been applied. This keeps the configuration straightforward for installations that use standard mechanical interfaces and standard drive matching. It is a PMB Series Brushless Servomotor and works with drives that deliver trapezoidal or sinusoidal current commutation.
