The electric motor of an electric motorcycle, also commonly known as "motor", refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Commonly used motors are DC motors, and there are two types of permanent magnet motors and series-excited motors. The part of the motor that rotates is called the rotor, and the part that does not rotate is called the stator.
The rotor or stator of a permanent magnet motor has one permanent magnet and the other is an enameled wire wound wire package. The rotor and stator of the series-excited DC motor are all wrapped in enameled wire, and the permanent magnet motor saves power compared to the series-excited DC motor. The magnet of the permanent magnet motor is afraid of high temperature, and if the temperature exceeds 110 degrees, it will demagnetize. The series-excited DC motor has no permanent magnets and does not have this problem. The series-excited DC motor is mounted on the outside and is driven by a pinion to the rear axle of the electric motorcycle to drive the large gear.
The contactor is used to control the forward and reverse of the electric motorcycle, and at the same time, it must be completed with the button. The wiring principle is a double interlocking positive and negative control circuit to realize the positive-reverse-stop working principle, which is safe and convenient. It makes the user more convenient when riding an electric motorcycle. www.guoweimoto.com
