Product Description:

The PMB33C-10201-02 brushless servomotor is built by Pacific Scientific within the PMB Brushless Servomotors series. It uses a permanent-magnet rotor and electronic commutation so a matched servo drive can regulate phase current for accurate torque and velocity control. This arrangement supports repeatable motion in light-duty automation such as indexing tables, packaging equipment, inspection systems, and electronic assembly stations. The motor is intended for applications where compact size and controlled response are more important than heavy-load output.

The motor uses a NEMA Size 34 frame, which corresponds to a 3.4-inch square mounting face and fits equipment designed for that bolt pattern. When operated on a 240 Vac bus, the winding reaches a nominal stall current of 3.8 ARMS, which helps set current limits and thermal protection under locked-rotor or stall conditions. Commutation timing comes from an onboard Hall Sensor, so the drive receives rotor position information without requiring an external resolver. Motor power and feedback signals exit through Flying leads with MS connectors, which allows the unit to be disconnected quickly and routed easily in compact machine layouts.

Load coupling is handled by a Round shaft, allowing torque transfer through clamp-style hubs or set-screw couplings without a keyed interface. Overtemperature monitoring is provided by an integrated PTC Thermistor, whose rising resistance can be used by the drive to trigger a controlled shutdown when internal heat climbs too high. The electromagnetic stack uses a multiple of 3, which increases copper capacity and supports higher torque density without changing the mounting footprint. The unit is a Brushless Servomotor, so it fits motion systems built around permanent-magnet AC servo operation and closed-loop drive control.
