Product Description:
The PMB33E-10100-02 brushless servomotor is produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. As an actuator for closed-loop industrial automation, the unit converts drive current into continuous torque and speed that position axes or drive machine tools with precise electronic control. When paired with a matching servo drive, it delivers compact rotary power without the brush wear associated with brushed designs and supports the dynamic response needed for indexing tables, pick-and-place gantries, or packaging spindles. The motor is suited to equipment that requires repeatable motion and stable speed control in a compact installation space.
Mechanical form factor follows the NEMA size 34 standard, so the 3.4-inch square flange lines up with commonly available gearheads and mounts. Power is connected through flying leads with AMP connectors, giving preterminated conductors that shorten panel wiring and remove the need for soldering. Current demand at stall reaches 7.4 ARMS when the drive is supplied from 240 VAC, and this value is used to size the power stage and thermal protection. Rotor position is measured by a resolver, allowing analog sine-cosine feedback that remains accurate at high temperatures and under electrical noise. The motor uses a round shaft, so a clamp-style coupling or other custom hub can be added without a keyway. This combination supports installation on a wide range of machine axes that use standard mounting hardware and flexible coupling arrangements.
Thermal safeguarding is handled by a factory-installed PTC thermistor, which rises sharply in resistance as winding temperature approaches its limit and can be wired into the drive inhibit circuit. The lamination depth uses a stack length multiple of 3, adding active iron and copper without changing the external frame dimensions. The motor also uses a low inertia rotor, which supports quick acceleration and deceleration during repeated motion cycles. This rotor characteristic is useful in applications with frequent starts, stops, and direction changes.
