What is?
is divided according to different principles of operation of the motor, in order to distinguish.
2
You know what?
divided by the power supply type: can be classified into DC motors and AC motors.
by the DC motor structure and working principle can be divided into: a brushless DC motor and brush DC motors.
AC motor can be divided into: single phase and three-phase motor.
According to the structure and working principle of division: can be divided DC motor, induction motor, synchronous motor.
rotor speed asynchronous motor always slightly less than the synchronous speed of the rotating magnetic field. Synchronous motor rotor speed regardless of load size remains the synchronous speed.
By Use: a drive motor and a control motor.
divided by the speed of operation: high-speed motor, low-speed motor, the motor speed and constant speed motor.

electric vehicle drive motor needs to have 4-5 times the overload in order to meet short-term acceleration or climbing requirements; the motor industry requires only 2-fold overload it. Maximum speed of electric vehicles requires 4-5 times the basic speed when cruising on the highway, and industrial motors only need to reachConstant power is two times that of the base speed. Electric vehicle drive motor vehicles and driving habits need to design a driver, but only according to typical industrial motors operating mode. The electric vehicle drive motor require a high power density (typically required to achieve 1kw / kg or less) and FIG good efficiency (over a wide speed range and have a higher efficiency torque range), thereby reducing weight and prolong driving range; while the industrial motors are usually power density, efficiency and cost into account, to optimize efficiency at rated operating point. Electric vehicle drive motors work required high controllability, high steady-state accuracy, good dynamic performance; and industrial motors is only a certain kind of performance requirements. Electric vehicle drive motor is mounted on a motor vehicle, a small space, at high temperatures, bad weather, and the frequent vibration, etc. harsh environments. And industrial motors typically operate at a certain fixed position.
