Product Description:

Pacific Scientific manufactures the PMB33F-00216-02 Brushless Servomotor for industrial automation systems. The motor provides dependable performance under variable duty cycles. It addresses demanding positioning and torque control tasks.

The PMB33F-00216-02 servomotor uses a NEMA Size 34 frame. The frame size provides standardized dimensions that simplify integration into existing machine layouts. The design has a stack length multiple. The extended stack length increases active material volume which supports higher torque density in a compact form. The motor nominal stall current equals 11.0 Arms. The defined current rating enables continuous torque generation without overheating under rated conditions. The continuous stall torque is specified at 5.42 Nm. The torque value secures accurate output for repetitive industrial cycles where constant torque is required. The peak torque reaches 16.1 Nm which accommodates rapid load changes. The rotor inertia is 0.404 kgm²x10-3 this low inertia value provides stable rotation with minimal overshoot during high-speed transitions. The static friction is measured at 0.169 Nm. The low friction level reduces resistance at start-up which allow smooth response at minimal drive input. The viscous damping coefficient equals 0.038 Nm/kRPM. It facilitates the effective conversion of energy for mechanical motion. Through oscillation control, the damping parameter stabilizes functioning under dynamic speed ranges.

The PMB33F-00216-02 servomotorhas a flat shaft design and this flat geometry ensures secure coupling with clamping hubs which prevent slippage under torque transfer. The output shaft includes compatibility with sealing arrangements. The sealing capability safeguards against contamination from external particles. The motor uses flying leads with MS connectors which allows reliable electrical interfacing with modular wiring assemblies. The construction eliminates integrated holding brakes. The Pacific Scientific brushless servomotor integrates defined mechanical and electrical attributes for consistent industrial automation applications.
