What is the speed of an electric car? Many customers will ask this question and give you a professional answer:
1: It is related to the current limit of the controller. Usually, the controller has 28A, 30A and 33A current limit. The larger the current limit, the faster the speed.
2: It is related to the magnetic steel piece of the motor and the winding method. The standard motor in the market is 30 mm magnetic steel. The longer the length and the quality of the magnetic steel sheet, the greater the effect energy obtained after the current is input. The good copper wire is a layer 1 copper winding with 5 layers. The speed varies depending on the winding method. There are usually two kinds of phase angle motors on the market, one is 60 degrees and the other is 120 degrees. Among them, the 60 degree starts slightly faster and the thrust is slightly larger, and the 120 degree is no more than 60 degrees. Large, the start is relatively soft and slow, but at full speed, 120 degrees will be faster than 60 degrees in speed.
