Product Description:

The PMB33C-10114-02 brushless servomotor is produced by Pacific Scientific for the PMB Brushless Servomotors series. This permanent-magnet unit works with matched drives to deliver closed-loop rotary motion in assembly cells, labeling stations, and similar automation lines. By converting electrical energy into precisely controlled torque, it acts as the prime mover for axes that demand repeatable positioning and fast cycle updates. In packaging machinery, it indexes pallets, while on light conveyor sections it governs feed rates.

Mechanical integration is straightforward because the motor follows the NEMA Size 34 flange pattern, letting it bolt to existing brackets without redrilling. At locked rotor, the winding can handle 3.8 ARMS, so the companion amplifier must be sized for that continuous current to avoid saturation. Position feedback arrives from an optical code disk that delivers 2048 ppr, giving controllers sub-degree resolution. Service wiring terminates as flying leads with AMP connectors, which simplifies connection to the drive and feedback circuits. To guard against overheating, an embedded PTC thermistor monitors stator temperature and prompts a controlled shutdown when its resistance rises sharply. This intrinsic protection helps extend winding insulation life in 24-hour service environments.

Commutation data is carried on the same tracks as incremental counts through the integrated digital encoder with commutation, eliminating separate Hall devices. A round shaft exits the housing and is compatible with clamp or set-screw couplings where keyed geometry is unnecessary. The laminated core uses a stack length multiple 3 arrangement, boosting torque without altering the frame size. This combination suits medium-inertia loads that require smooth low-speed motion and rapid acceleration.
