The electric motor commonly used in electric tricycles is a direct current motor, and there are two types of permanent magnet motors and series excitation 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 enameled wire wound wire packages. The electric motor of the electric tricycle, also commonly known as "motor", refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Power motor, permanent magnet motor saves power compared to 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 through a chain to the rear axle of the electric tricycle to drive the large gear. The contactor on the car is used to control the advancement and reversing of the electric tricycle. 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, safe and convenient.
