Product Description:

The PMB33F-00214-00 belongs to the PMB Brushless Servomotors series produced by Pacific Scientific. It is a three-phase permanent-magnet unit intended to generate controlled torque in automation cells, motion stages, and material-handling axes. When paired with a digital servo drive and encoder feedback, the motor supports closed-loop positioning for applications that need repeatable starts, stops, and speed changes. Its permanent-magnet design also supports efficient servo response during continuous-duty operation.

Mechanical fit is set by the NEMA Size 34 frame, so mounting uses a 3.4-inch square pilot common to many drive packages. Thermal loading is limited by a nominal stall current of 11.0 ARMS when the windings are energized from a 240 VAC bus, so the amplifier must supply that current continuously without exceeding motor insulation limits. Field wiring exits through flying leads with MS connectors, providing strain-relieved cabling that mates quickly to panel receptacles and supports straightforward routing inside the machine. Position feedback comes from a rotor-mounted digital encoder with commutation that provides an incremental output of 2048 ppr, giving the drive 12-bit angular resolution for phase advance, velocity regulation, and stable low-speed control.

A flat shaft terminates the rotor, allowing clamp-style couplings to grip the output without adding keyseats and helping preserve concentricity at the coupling. The electromagnetic core uses a stack length multiple of 3, which increases usable torque while keeping inertia appropriate for mid-mass loads that must reverse direction rapidly. The unit is supplied as a standard motor, so it uses the standard configuration for this model rather than a custom build. This arrangement supports general servo installations that use standard electrical and feedback features.
