Product Description:
The PMB31D-20216-01 servo motor is ideal for use in factory automation systems. The servo motor is manufactured by Pacific Scientific. It performs reliably, is easy to control, and uses power efficiently. This servo motor is perfect for a variety of industrial applications due to its efficiency and lifespan features.
The PMB31D-20216-01 servo motor can operate at 8400 rpm when no load is applied, and the rated speed is 5000 rpm. It has an encoder with 4096 ppr for accurate position feedback. Because of its compact size and NEMA 34 chassis, this motor can be mounted in a variety of ways. Power delivery is effective under varied load situations due to the sustained stall torque of 2.1 Nm (18.7 lb.-in.) and peak rated torque of 6.2 Nm (54.7 lb.-in.). The motor guarantees long-term performance with its constant rated torque of 1.7 Nm (15.0 lb.-in.). For versatile integration and efficient application usage, the motor comes with flying leads with MS connections. The winding current of the servo motor is 5.4 A, and it maintains a stall current of 5.1 A continuously. Efficient motor performance is enhanced by its inductance line-line of 5.2 mH. The PC8x4 servo drive model is tailor-made for this particular motor.
The PMB31D-20216-01 servo motor comes with square key shafts in sizes 2 and 3, which ensure a safe connection in mechanical systems. The maximum stall torque of 6.2 Nm (55.0 lb.-in.) adds to the motor's capacity under heavy loads. This motor guarantees fast response times with an inertia of 0.14 × 10⁻³ kg·m² (1.21 × 10⁻³ lb.-in.-sec²). At maximum torque, the current is 15.3 A RMS, providing the necessary power for challenging tasks. The motor is cost-effective and durable, and it is designed to meet operational needs with minimal maintenance.
