Product Description:

The PMB33F-10114-02 is a brushless servomotor manufactured by Pacific Scientific as part of the PMB Brushless Servomotors series. Designed for closed-loop motion platforms, the motor supplies precise rotary power so that industrial axes can accelerate, hold position, and reverse with repeatable accuracy. It is commonly used with digital drives in packaging lines, material handling equipment, and semiconductor tools where compact size, consistent torque, and low maintenance are important.

The housing follows the NEMA Size 34 standard, giving a 3.4-inch square mounting face that simplifies interchange with other frame-34 devices. Position feedback is supplied by a 2048 ppr incremental encoder, and this resolution lets the drive command very small shaft movements when the application uses suitable gearing. At 240 V AC, the motor can withstand a continuous stall winding current of 11.0 ARMS, which is the steady-state current the drive must deliver for maximum holding torque without overheating. Power and signal terminations exit the stator through flying leads with AMP connectors, so wiring can be routed without a separate junction box. Commutation and incremental feedback are combined in a digital encoder with commutation, allowing the controller to sense rotor position every electrical cycle for smooth sinusoidal drive.

Thermal protection is built in through a PTC thermistor, which changes resistance sharply near the insulation limit and prompts the drive to reduce current before winding damage occurs. A round shaft permits direct coupling with belts, pulleys, or flexible couplings without the fit issues sometimes associated with keyed or flat designs. The electromagnetic section uses a stack length multiple of 3, which increases active magnetic length while keeping the same frame size. The motor belongs to the PMB Brushless Servomotors series, so it follows the product line used for compact brushless motion applications.
