Product Description:

The PMB33E-10214-02 is a brushless servomotor produced by Pacific Scientific and delivered within the PMB Brushless Servomotors series. In automated machinery, it functions as a torque source that responds precisely to commanded current from a compatible drive, allowing closed-loop position or velocity control on conveyors, pick-and-place gantries, and indexing tables. Because it uses brushless operation, the motor avoids brush wear and supports stable motion performance in applications that require frequent starts, stops, and direction changes. Its compact format also suits equipment where available mounting space is limited but repeatable servo response is still required.

The motor uses a NEMA Size 34 frame, which gives it a standardized mounting pattern for this motor class. Its magnetic circuit uses a stack length multiple of 3, adding active material to support higher continuous torque within the same basic frame size. At rated line voltage, the winding draws a nominal stall current of 7.4 ARMS, which is useful for matching the motor to a compatible amplifier and setting current limits within the drive. Rotor position feedback is provided by a 2048 ppr optical code wheel, and the integrated digital encoder with commutation supplies both shaft position and commutation information so the control system can maintain accurate current phasing during motion and at standstill.

Power and signal cabling exits as flying leads with MS connectors, which allows the motor body to pass through tight machine openings before final electrical connection is made. For thermal protection, a PTC thermistor is embedded in the stator winding, giving the control circuit a clear indication when motor temperature rises beyond its normal range. The output shaft is round, which supports coupling arrangements that rely on clamping or press-fit attachment methods. The motor is part of the Pacific Scientific product line, and its combination of encoder feedback, thermal monitoring, and standardized mounting makes it suitable for compact servo axes that require controlled acceleration, stable low-speed operation, and consistent repeatability over long production cycles.
