What are the driving technical requirements of hub motor

Considering the complexity of ev operating conditions and the characteristics of hub motor driving mode, the technical requirements for hub motor mainly include:

(1) Due to the limited vehicle weight and hub space, hub motor is required to have a high torque density;

(2) In order to meet the requirements of fast start, acceleration, hill climbing and frequent start and stop of the car, the hub motor should have a very wide speed range and strong anti-overload ability, and can maintain high efficiency in a wide speed and torque working area;

(3) Wheel motor should be able to withstand high temperature, low temperature, severe vibration and the influence of changeable weather, can work normally in a variety of harsh environment;

(4) In a variety of complex driving conditions, hub motor should have strong anti-interference ability and high control accuracy.
