Product Description:

The PMB33F-00114-00 is a brushless servomotor built by Pacific Scientific for closed-loop motion control. In automated systems, it delivers regulated torque and position control for pick-and-place arms, indexing tables, and similar axes that require repeatable rotary motion. The motor converts electrical input into controlled shaft movement so the connected drive can follow programmed speed and position commands while maintaining synchronized feedback to the controller. That arrangement suits positioning and indexing duties where stable response is needed over repeated operating cycles.

This model uses NEMA Size 34 mounting, so its faceplate and pilot diameter match common 3.4-inch frame installations. Power conductors exit as flying leads with AMP connectors, which allows flexible cable routing through machine frames and enclosed assemblies. Position feedback is delivered by an incremental encoder rated at 2048 ppr, allowing the drive to resolve fine angular movement for accurate control. At rated stall on a 240 VAC bus, the motor draws up to 11.0 ARMS, which is useful when matching the motor to a compatible amplifier. The motor has a flat shaft end, so a setscrew coupling can seat against the machined surface without keys or splines.

The feedback package uses a digital encoder with commutation, so rotor position and commutation signals come from one device. The motor uses a stack length multiple of 3, which increases active magnetic length without changing the frame outline. It is supplied as a standard motor, indicating a standard winding and sensor arrangement rather than a custom configuration. Combining commutation and position feedback in one device reduces the number of separate feedback components at the motor. The longer magnetic stack also adds torque-producing material within the same mounting envelope, which is useful where available machine space is limited.
