How to quickly determine two rounds of brushless dc motor of motor is 60 degrees or 120 degrees of motor?
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 have 3 lamp hall light is bright or are destroyed at the same time, at the same time, that is 60 degrees motor. Without these two conditions state that the motor is 120 degrees.

48 v and the following motor as early as a few years, mostly in the motor at 60 degrees. In recent years, 60 v20ah basically is 120 degrees of motor vehicle.
brushless motors and brushless controller, a total of 36 kinds of connection. In accordance with the original method is a kind of a try is more troublesome, as many as 36, try best to do mark, otherwise easy to repeat. But there is only one is 60 degrees of motor and a state of inversion. No response for other connection, motor. 120 degrees motor has three kinds of forward and three reverse, that is to say, there are 6 kinds of state motor can turn.
but turn positive, though it is, 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 the no-load current is not more than 1. 2A。
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, 120 degrees of motor and controller hall line without the line, direct on line. Whether 60 degrees electric motor or 120 degrees, hall line b phase, in the middle of the 6 pin plug in a single span. We can adjust the order of the three phase line to find the right one. Motor smooth operation when the connection is right, there is no noise. The stator
if appear, the motor reverse, there is a quick way: we can use, hall switch wire line 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 connection again for up to six times, to realize the adjusting motor running direction.
