Product Description:

The PMB33C-00116-00 is a brushless servo motor manufactured by Pacific Scientific and supplied within the PMB Brushless Servomotors series. In automated machinery, this motor converts electronically commanded currents into precise rotary motion, allowing closed-loop positioning and velocity control for pick-and-place heads, indexing tables, and similar axes. Its design aligns with typical servo drive architectures in which a feedback device signals rotor position to a compatible amplifier, allowing repeatable movement and stable speed regulation during continuous machine cycles.

Electrical and electromechanical data show how the unit fits into a drive system and how its connections are arranged. An onboard digital feedback device delivers an angular reference of 4096 ppr, giving controllers fine interpolation for smooth motion profiles. With the shaft locked, the windings can hold a continuous load at 3.8 ARMS from a 240 VAC bus, and this value is used to size the power stage and cabling. The frame conforms to NEMA Size 34, so the bolt circle and pilot diameter match standardized mountings commonly found on small gantries. Power and feedback exit through flying leads with AMP connectors, so the connection points arrive pre-terminated. Internal commutation signals come from a digital encoder with commutation, eliminating the need for separate Hall boards.

The motor uses a flat shaft to transmit torque without relying on keyways, which can help reduce backlash in compact couplings. The electromagnetic package uses a stack length multiple of 3, which extends the active iron and increases torque density while keeping the outer frame outline unchanged. Because it is supplied as a Standard Motor, no special windings or seals are added. It is also listed as a PMB Series Brushless Servomotor for use with compatible Pacific Scientific drives.
