Product Description:

The PMB31D-10116-02 is a small, powerful and extremely reliable product designed by Pacific Scientific for a lasting and reliable operation of state-of-the-art machines. This motor unit is a rugged brushless motor with an anti-cog design that makes it possible for it to maintain smooth and low-speed operation. The design of this industrial motor is according to the IP40 classification, although this protection class is low compared to conventional series, the PMB31D-10116-02 makes up for it in its ability to support a high volume of applications and its improved cost effectiveness. The operation of this industrial motor is relatively easy for properly trained personnel; the motor is delivered with a document containing information on the proper operating conditions for it.

The PMB31D-10116-02 does not produce a high amount of heat during operation; however, there is a thermistor installed at its winding to help drive controllers to detect any risk of overheating and shut down the motor before any damage happens. The size of this servo motor is classified under NEMA Size 34; it is also equipped with a digital encoder with commutation and the ability to operate at a high-resolution level.

The PMB31D-10116-02 has a low cost of ownership since customers do not have to carry out frequent maintenance operations on it. The unauthorized modification of this motor is also prohibited; any attempt to do this will void the warranty covering it and can cause accidents. The inertial level of this servo motor unit during operation is about 0.14 kilograms per meter square. There is no air blower directly attached to this motor; however, its design makes temperature regulation relatively easy through natural convection.
