brushless motor manufacturer for you test the resistance of the brushless motor control for multimeter reverse diode or two brushless motor manufacturer test controller of the positive and negative power brushless motor factory in line with the motor three wire, the resistance value between normal measured resistance value should be the basic consistent, if the resistance of a wire, then the controller damage resistance under the condition of normal, line detection hall handle 5 v voltage is normal, otherwise the damage of brushless controller. How to detect the stand or fall of hall, a hall element is first one foot after 5 v power supply two brushless motor manufacturer feet grounded 3 feet by output, again, the power supply is connected with a multimeter with 3 feet following its output voltage measurement, reoccupy magnet poles nearer to the front of the hall component, observe the multimeter output voltage, and then switch to another near the magnetic poles, observe whether the voltage jump, jump, such as Spänning visar att hallelementet är bra, om ingen spänningsförändring visar att hallelementet är dåligt.
