PMB21D-10116-00
The PMB21D-10116-00 from Pacific Scientific’s PMB Brushless Servomotors series is a high-performance synchronous brushless servomotor designed for precision motion control in industrial automation. Featuring a continuous stall torque of 0.64 Nm and a rated speed of 1,300 rpm, this NEMA Size 23 motor delivers consistent and reliable torque for a wide range of positioning and servo applications. Its primary function is to provide accurate speed and torque control in demanding environments, making it ideal for tasks requiring rapid response and repeatable performance, such as conveyor indexing, pick-and-place systems, and robotic joint actuation.
Built to exacting standards, the PMB21D-10116-00 is equipped with Class F winding insulation for superior thermal endurance and an exposed-lamination design that optimizes heat dissipation. The rotor contains high-energy neodymium iron-boron magnets for elevated torque density, enabling a peak stall torque of 1.27 Nm while maintaining a compact package. Feedback is provided by a precision digital encoder with commutation offering 4096 ppr, and the motor supports additional Hall sensors, resolver, encoder integration for advanced control schemes. With a shaft design of round steel, rotor inertia of 0.023 kg·m², and a motor length of 112.8 mm, this servomotor balances dynamic response with structural rigidity.
The PMB21D-10116-00 features flying leads with AMP connectors for secure, low-impedance power and signal connections, enhancing installation flexibility and serviceability. Its Class F insulation and robust bearing shielding ensure resistance to heat and particulate ingress, translating to extended maintenance intervals and high uptime. With a no-load speed of 3,600 rpm, the motor excels in applications requiring rapid acceleration and precise deceleration profiles. Its standardized stack length multiple of 1 simplifies system configuration, while compatibility with a variety of servo drives (PC8xx, SC9xx series) streamlines integration. In industrial settings, this motor delivers cost-effective solutions by combining high torque density, efficient cooling, and durable construction, ultimately improving process throughput and reducing total cost of ownership.
