Product Description:

The PMB33E-00101-00 is a brushless servomotor manufactured by Pacific Scientific and assigned to the PMB Brushless Servomotors series. As a compact rotary actuator, it delivers closed-loop speed and position control for pick-and-place gantries, packaging axes, and other motion modules that demand rapid acceleration with repeatable accuracy. The motor integrates windings, rotor magnets, and feedback devices into a single frame so it can be coupled directly to gearheads, lead screws, or timing belts. Its compact format also helps it fit axes where available mounting space and moving mass are both limited.

This unit uses a NEMA Size 34 frame, so it fits mounting patterns commonly used with standard reducers and brackets. The motor has a nominal stall current of 7.4 ARMS at 240 VAC, which indicates the current level associated with high torque output at standstill. Rotor position is derived from a three-phase set of Hall sensors, allowing low-speed commutation before a higher-resolution feedback device is available. Power and signal conductors exit the housing as flying leads with AMP connectors, which simplifies connection to the drive and feedback harness. The motor uses a flat shaft end so clamping hubs can transmit torque without requiring a keyed coupling.

It is supplied as a standard motor, so the configuration follows the regular production option set rather than a special build. The magnetic stack is extended by a multiple of 3, which increases available torque within the same mounting face and helps when the driven load has higher inertia. That longer stack can reduce the need to move to a larger frame when moderate torque gains are needed in the same mechanical envelope. Within the Pacific Scientific product range, this motor is part of the PMB Brushless Servomotors line and uses the compact packaging typical of that series. This arrangement suits motion axes that need repeatable rotary control in limited installation space.
