Product Description:
The PMB33C-10216-01 is a brushless servomotor produced by Pacific Scientific and positioned in the PMB Brushless Servomotors series. In automation cells, it supplies closed-loop rotary motion, allowing drives to position loads accurately without gear reduction and to maintain repeatable movement during frequent start-stop cycles. An internal permanent-magnet rotor works with electronic commutation so that commanded torque follows the control loop in real time, making this unit suitable for indexing tables, pick-and-place axes, and similar duty cycles.
The motor frame matches the NEMA Size 34 envelope, so its 3.4-inch square face fits common mounting plates while leaving space for feedback and power cabling in compact machine layouts. A nominal stall current of 3.8 ARMS at 240 VAC indicates the required drive rating and the continuous heat that must be removed from the stator during sustained load. Position feedback is delivered through a 4096 ppr optical encoder, giving 12-bit resolution for velocity and position loops while supplying three commutation tracks so that the drive always knows the electrical angle for stable low-speed control. Power and feedback exit the housing through flying leads with MS connectors, which shorten installation time because crimping or soldering is unnecessary. The sensing element is a digital encoder with commutation; digital outputs eliminate drift and simplify wiring by sending differential signals directly to the controller.
A round shaft permits direct clamping couplings and reduces alignment errors that occur with keyed designs. The fitted shaft seal restricts oil or coolant ingress at the output journal, extending bearing life in washdown or lubricated environments. Magnetic stack height is set to a multiple of 3, increasing torque without altering the cross-section. The motor is intended for use with Pacific Scientific drives that provide matched current, encoder power, and commutation signals, keeping the feedback and power interfaces consistent across the axis.
