How many motors are there?
Permanent magnet DC motor is used in electric vehicle motor. The so-called permanent magnet motor, refers to the motor coil using permanent magnet excitation, and do not use coil excitation mode. In this way, the electric energy consumed by the exciting coil is eliminated, and the electromechanical conversion efficiency of the motor is improved, which can reduce the traveling current and prolong the continuous mileage for the electric vehicle with Limited vehicle energy
The working voltage of the electric motor is different from the machine manufacturer and model, and the working voltage is different. There are 48 volts, 50 volts, 60 VOLTS, 64 volts, 70 volts, 75 volts, and so on. Usually, the speed of the electric vehicle depends on its working voltage and current. That is to say, the working voltage and the working current are in direct proportion to the speed.
According to the general form of electric motor electric motor to points, can be divided into brushless motor and brushless motor two categories; according to the mechanical structure of the motor assembly points, generally divided into "teeth" (high speed motor, need to go through the gear) and "toothless" (without motor torque output any reduction in two categories).
