Product Description:

Designed by Pacific Scientific, the PMB31D-10216-02 brushless servomotor is lightweight and compact in size. This motor’s shaft can be either downward or upward with its vertical mounting option. The product showcases a round design for its shaft. This device features four mounting holes on its shaft. The unit uses 10 socket-lead cap screws to help with its mounting. It portrays a NEMA mounting style. This motor delivers excellent results for high-volume applications.

The product’s magnets have high resistance to demagnetization and contribute to overall cost-effectiveness. This device’s permissible load limits shouldn’t be exceeded. The unit’s bearings have a long lifespan because of two shielding. It is highlighted by exposed laminations. This motor’s maintenance or repair must be done after disconnecting it from its power source. The product’s maximum static friction has been set at 0.09 Nm. This device isn’t intended to be used at a peak current and/or torque that is more than four times its continuous rating. The unit’s thermal resistance is 1.08 °C/W and its thermal time constant is close to half an hour. Its mounting holes have a 0.220-inch diameter with +/-0.005-inch tolerance.

This motor’s speed is lowered to 40% of the standard speed when it supports one-phase line operation at 120 VAC. The product supports only encoder feedback when used with a digital drive. This device has low power consumption. The unit also features efficient energy conversion. Its magnets portray the ability to withstand high temperatures. This brushless servomotor features a 8400 rpm speed when it is run without a load.
