Product Description:

This PMB31D-20114-02 brushless servomotor crafted by Pacific Scientific features exposed laminations. The motor uses ten cap screws for its mounting. This product uses shielded cables for the connection. The device’s continuous torque is set by its maximum temperature. This unit operates in a closed loop with a supporting servo drive. Its encoder feedback depicts a high resolution rate. The motor is safeguarded against overloading or overheating by the integrated thermistor.

This product weighs 5.5 kg without its encoder. The device is best intended for light-industrial applications. This unit isn’t meant to be operated for residential use. Its storage should be done in a dry and dust-free place. The motor delivers smooth operation with low noise. This product depicts high synchronization. The device can function for a long period and a high speed. This unit’s servo drive assesses the performance of the motor using the feedback. It comprises a high torque-to-inertia ratio.

The motor’s encoder is fitted onto its shaft. This product delivers consistent torque throughout its complete speed range. The device is put into operation in industrial automation systems in robotic arms, CNC machines, and pick-and-place equipment. This unit portrays no cogging while it is operated. The brushless servomotor-related servo drive makes real-time adjustments by comparing the actual position and command. This product’s permanent magnets tend to get demagnetized because of overheating. The unit’s high power as well as torque at the same time is a result of the exposed laminations. Its mating connectors are intended to be bought as separate sub-items.
