How to quickly determine two rounds of electric motor is a motor or degrees? This method is very simple, we use the garage treasure to connect the hole plug of the machine. Then slowly turn the motor with the hand, both clockwise and counterclockwise. If there is a hole in light is bright or are destroyed at the same time, at the same time, that is the degree of motor. Without these two kind of state that is motor. A few years earlier to and including 450/750v motor, in the majority with degree of motor. In recent years, VAH motor vehicles are basically degrees. Brushless motors and brushless controller, total have a connection. In accordance with the original method is a kind of a try is more troublesome, as many as kinds, try best to do mark, otherwise easy to repeat. There is only one is not excessive motor and a state of inversion. No response for other connection, motor. Degree of the motor have a forward and reverse, that is to say, there is a state of motor can turn. But although is positive rotation, such as hearing voices feeling motor speed is very fast, but the motor sound very loud, a weird. It is not normal. In this state will need to adjust again. When we are connected correctly, the motor should be smooth operation, no obvious noise, and no more than idle current. A。 You may at the time of replacement controller, often motor reversal. Listen to the motor speed is normal, no noise, motor rotation speed is controlled by turning the, but the direction of rotation is opposite. So how do we quickly, make inversion of motor positive rotation? In general, the degree of motor and controller hall line without the line, direct on line. Whether electric motor or degrees, hall line b phase, in the middle of the hole plug in a single span. We can order by adjusting phase thread, find the right one. Motor smooth operation when the connection is right, there is no noise. If appear, the motor reverse, there is a quick way: we can use, switch lines to hall of a, c, coarse phase line switch a and B. Or another, relatively primitive method, the motor hole line switch a, c, motor and controller main line for the greatest number of connection, to realize the adjusting motor running direction.
