Sometimes, when a brushless motor is powered on, the motor equipment does not respond, so users want to ask what the reason is. Therefore, today, the editor will talk about this issue in order to help you quickly solve this situation when using brushless motors.
1. Loose or detached wire connectors, damaged wire sheaths, and grounding can cause a short circuit in the brushless motor.
2. The fan pulley is too loose or has oil slipping.
3. Wear, burn or oil stains on the motor commutator, open or short circuit in the magnetic field coil, open or short circuit in the armature coil, short circuit in the commutator, and grounding of the insulated carbon brush holder.
4. The contacts of the regulator or throttle are burned or contaminated, the balance resistor is broken, the bridge wire of the voltage regulator is burned, the spring tension of the voltage regulator is weak, the air gap is too small, the limit voltage adjustment of the voltage regulator is too low, the closing voltage of the circuit breaker is too high, or the parallel coil is broken.
If the brushless motor is not powered on, it must be checked in a timely manner, otherwise it may not only affect work efficiency, but also cause certain damage to the equipment, so it needs to be repaired in a timely manner.
