Product Description:

The Pacific Scientific PMB Brushless Servomotors series includes the PMB33F-00100-00, a brushless servomotor for closed-loop position and speed control in automated machinery. It converts electrical input into rotary motion and, when paired with a compatible drive, maintains accurate torque delivery for indexing tables, gantries, and packaging axes. The motor is intended for applications that need repeatable speed regulation and stable positioning without the brush wear associated with brushed motor designs. This makes it suitable for motion systems where rapid starts, stops, and direction changes are part of normal machine operation.

The motor uses an ANSI frame in NEMA Size 34, so it matches gearboxes and mounting patterns commonly used with stepper units of the same footprint. At 240 VAC, the winding has a nominal stall current of 11.0 ARMS. Power and feedback leave the housing through flying leads with AMP connectors, which provide a direct cable exit and keep the connection hardware outside the motor body. Rotor position is measured by a resolver, allowing the drive to track shaft angle for commutation and closed-loop speed control across the operating range.

The motor uses a flat shaft end, providing a simple drive surface for set-screw couplings when a keyway is not required. It is supplied as a standard motor, so it follows the regular winding and mechanical configuration rather than a custom build. The active magnetic length uses a stack length multiple of 3, which gives the motor a longer lamination stack than the smallest version in this frame while keeping the same outside diameter. That longer stack increases the available magnetic path and supports higher continuous torque within the same mounting envelope. The shaft form also simplifies coupling selection in compact assemblies that do not need keyed torque transmission.
