The precautions for use of the permanent magnet brushless DC motor

Nov 18, 2017

In general, the permanent magnet brushless DC motor is not allowed to anti-phase braking operate at rated voltage, because it will cause demagnetization of the permanent magnet. However, if you must do this, it is not impossible, but need to take some necessary protective measures, such as installing the current-limiting resistance to limit the current, so as to avoid excessive flow to prevent the permanent magnet brushless DC motor being damaged.
