Electric Car use electric motors instead of fuel engines and are driven by electric motors without the need for automatic transmissions. Compared with automatic transmissions, motors have simple structures, mature technologies, and reliable operation.
Traditional internal combustion engines can limit the speed when efficiently generating torque to a narrow range, which is why traditional internal combustion engine vehicles require large and complex transmission mechanisms; while electric motors can efficiently generate torque in a fairly wide speed range, and do not require gear shifting and transmission devices during the driving of
New Car. They are easy to operate and have low noise.
Compared with hybrid vehicles, Electric Car use a single source of electricity, and the electronic control system greatly reduces the internal mechanical transmission system of the vehicle, has a simpler structure, and also reduces the energy loss and noise caused by the friction of mechanical parts, saving space and weight inside the vehicle.
The motor drive control system is the main executive structure of Electric Car during driving. The drive motor and its control system are one of the core components of Electric Car (battery, motor, electronic control). Its driving characteristics determine the main performance indicators of vehicle driving, and it is an important component of Electric Car.
The three major categories of Electric Car, fuel cell vehicles (FCVs), hybrid Electric Car (HEVs) and Electric Car (EVs), all use electric motors to drive the wheels. Choosing a suitable electric motor is an important factor in improving the cost-effectiveness of various Electric Car. Therefore, it is extremely important to develop or improve an electric motor drive method that can simultaneously meet various performance requirements during vehicle driving and has the characteristics of durability, low cost and high efficiency.
