Product Description:

The PMB33C-00216-01 brushless servomotor is manufactured by Pacific Scientific as part of the PMB Brushless Servomotors series. It is intended for servo axes that demand rapid acceleration, repeatable speed profiles, and tight position control in industrial automation cells. When paired with a compatible drive, the motor supplies controlled torque to conveyors, rotary indexers, and lightweight gantries without brushed contact, which reduces wear during continuous duty. Its brushless design also removes commutator maintenance and helps keep motion performance stable over long operating periods.

With a frame classified as NEMA Size 34, the motor fits standard 3.4-inch mounting patterns used on many machine axes. Its nominal stall current at 240 VAC reaches 3.8 ARMS, which is the current the amplifier must supply while the rotor is held stationary. Feedback is generated by a 4096 ppr optical channel count, allowing fine position updates for low-speed control and short indexing moves. The integrated feedback device is a Digital Encoder with commutation, so the drive receives rotor position data and phase alignment signals from one assembly. Power and signal connections use flying leads with MS connectors, which helps route cabling through tight cabinet spaces and around moving machine members.

The shaft end is machined with a flat so set-screw couplings can grip the output shaft with consistent alignment. A shaft seal is available to help block dust or splashed coolant from entering the front bearing area. Electromagnetic output is increased by a stack length multiple of 3, which uses three lamination sections to raise torque density without changing the motor diameter. That longer active stack increases torque capability for the same face size, which is useful where machine space is limited. The motor remains within the dimensional envelope associated with the PMB Brushless Servomotors series, helping it fit compact machinery layouts.
