Product Description:

The PMB33F-10100-02 is a brushless servomotor manufactured by Pacific Scientific for the PMB Brushless Servomotors series. This unit converts three-phase electrical input from a matched servo drive into controlled rotary motion, providing precise speed and torque regulation for automated equipment. Its design suits positioning axes, indexing tables, and other motion-control tasks that require repeatable response with low maintenance. Because it is brushless, the motor avoids commutator wear and supports sustained operation in demanding servo applications.

At the mechanical interface, the motor frame conforms to NEMA Size 34, allowing installation on standardized size-34 mounting patterns. Electrical requirements include a nominal stall current of 11.0 ARMS at 240 VAC maximum, which helps match the motor to a suitable servo amplifier. Rotor position feedback is provided by a Resolver, which returns angle signals that remain reliable in electrically noisy and high-temperature environments. Power and feedback wires exit the stator as flying leads with AMP connectors, allowing connection without opening the housing. Motion is transmitted through a round shaft, making the motor compatible with common clamp or set-screw couplings for light to moderate loads. These features support accurate operation in closed-loop motion systems where stable feedback and predictable torque response are required.

Additional features address thermal protection and torque output. A PTC thermistor is installed in the winding and increases in resistance as temperature rises, allowing the drive to reduce current before insulation is overstressed. Output is increased by the motor's stack length multiple 3, which uses three lamination stacks to raise torque while keeping the same frame size. The motor also uses standard mounting geometry, which helps it fit brackets and mechanical interfaces commonly used with this frame.
