Some friends in the use of brushless DC motor, found that can not start, can not be energized, a moment also do not know what the reason, more headache, so what is the reason can not start it?Vacuz give you an analysis! Hope it can help everyone!
1. The power supply voltage may be insufficient, the voltage is too high and unstable, or the line may have poor contact joints loose or off or even short circuit, the wire skin has damage, resulting in DC brushless motor can not start.
2. The load of DC brushless motor is too large, exceeding its own load torque, resulting in failure to start.
3. Hall components out of order, will also lead to DC brushless motor can not start.
4. The controller control line is not connected or less connected, resulting in the motor can not start.
5. Demagnetization or demagnetization of motor rotor magnets, resulting in unstable magnetic field, will also affect the motor start.
6. Brushless DC motor rectifier wear, burned or oiled, magnetic field coil disconnection or short circuit, etc., will cause the motor can not start.
DC brushless motor does not energize can not start, must be timely check, otherwise it will affect the efficiency of work, can be based on the above-mentioned points of the reasons to investigate and repair, to ensure the normal use of the motor.
