Product Description:

The PMB33F-10200-00 brushless servomotor is produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. It converts electrical power into controlled rotary motion for axes that must start, stop, and hold position precisely in packaging, electronics assembly, and light material-handling equipment. Permanent-magnet excitation and three-phase drive electronics give the motor quick response during repeated indexing, short acceleration ramps, and frequent reversals. The brushless format also avoids commutator wear, which supports low-maintenance operation over repeated duty cycles. When paired with compatible feedback and drive electronics, it serves as a primary actuator for positioning and speed control in compact automation systems.

Physical dimensions follow the NEMA Size 34 frame code, so the mounting face measures 3.4 inches square and accepts standard flange hardware used on many small machine axes. Power and feedback leave the housing through flying leads with MS connectors, which helps when harnesses must be routed through narrow panel spaces or around moving assemblies. At standstill, the winding can draw up to 11.0 ARMS from a 240 VAC rated drive, supporting continuous torque production at zero speed. Rotor position is reported by a resolver, an analog sensor that tolerates heat and vibration well while providing angle feedback to the controller. Motion is transferred through a round shaft, so couplings or pulleys are mounted with clamp or press-fit methods instead of keyways.

Within the PMB Brushless Servomotors range, this model uses a stack length multiplier of 3, so three laminated stator sections are combined to raise torque while preserving the Size 34 footprint. It is supplied as a standard motor, which means no special winding or sealing option changes the basic thermal arrangement of the unit. The design used by Pacific Scientific allows the same mechanical package to cover multiple torque points, which helps keep adjacent mounting and coupling geometry consistent across similar axes. This approach preserves mounting space where cabinet depth and machine clearances are limited.
