Product Description:

A brushless advanced servomotor from the PMB series, the Pacific Scientific PMB31D-10116-00 is appropriate for applications requiring precise motion.

The combination of NEMA Size 34 frame and single-length stack configuration provides it with a wide variety of uses in mid-sized automation systems, CNC machining, and robotics. It supports a digital position encoder, commutation with a resolution of 4096 pulses per revolution, providing feedback on position and speed, and closed-loop control. Its connector arrangement is flying leads, AMP connectors, which can provide flexibility of electric installation into a custom or OEM-compatible system. The PMB31D-10116-00 has a continuous stall torque of 2.1 Nm (18.7 lb-in) and has a maximum torque of 6.2 Nm (55.0 lb-in), so it can manage higher acceleration and deceleration requirements. The motor performs with a nominal of 5000 RPM, which makes it capable of meeting performance standards with robust applications.

It possesses an operating stall current of 5.4 ARMS and a maximum supply voltage of 240 VAC, which gives it reliable torque output under a load condition. It also has an electric capability of being able to run with up to 240 V AC, or 320 V DC on the bus, enabling it to be used with numerous servo drives. Rotor inertia is small at 0.14 kg·cm² (1.21 lb-in²), allowing fast dynamic response and smooth, high-speed control. The motor weighs about 5.2 kg and is constructed with the use of winding type D. With regard to its IP40 enclosure level, it offers very little protection against solid objects and should only be utilized in hygienic, regulated environments. It can be purchased at Wake Industrial with a one-year warranty.
