① Some power hybrid ISG application instances.
The position of the motor and the constituent structure of the motor are shown . The ISG motor uses a permanent magnet synchronous motor, which is composed of coil stator 2. permanent magnet rotor 3 and middle shell. The motor stator 2 is fixed on the transmission shell through the stator 7, and the permanent magnet rotor 3 is connected to the end of the engine crankshaft. When the ISG motor starts the engine, it is used as an electric motor to drive a crankshaft; other operating conditions are used to rotate the generator with the crankshaft and transmission input shaft.

The main functions of ISG motors: engine starting, regeneration braking, and providing engine assistance; the output power of the motor is 15kW and the mass is 20kg, which can generate a three -phase AC power with a rated voltage 124V; the speed is not generated when the speed is less than 100R/min.
Because the automotive power system and the energy storage system are different from the ISG motor working system, the two sets of high -voltage storage devices are required. The high -voltage electricity generated by the generator needs to be used by the power control system to control the inverter (AC/ AC/ DC) Save the high -voltage lithium battery after conversion, and part of the energy converted into DC is converted through high and low voltage (DC/DC).
At the beginning of the car, the power control system controls the power of the high -voltage battery to convey the DC/AC according to the request, and supply the ISG motor to the ISG motor. When the ISG motor is used as an electric motor, it provides the required starting torque for the crankshaft rotation.
When the automotive engine or transmission system provides power, the ISG motor enters the power generation mode, and the three -phase AC electricity generated is converted from the power control device inverter (AC/DC) to DC electricity to charge the high -voltage battery, and passes through the DC/DC converter to the 12V vehicle. Electric system power supply.
When the car taxi or deceleration, the kinetic energy of the vehicle will be converted into electrical energy by the ISG motor. This process is called energy regeneration.
In the power generation mode, the promoted electric opportunity generates AC power, which is affected by the amount of power generation. During the deceleration, the power management system will control the deceleration torque and the engine of the engine according to the slope of the pavement and the speed of the taxi.
② All -hybrid ISG application instance.
The Honda IMA hybrid system consists of 4 parts: engine, motor, CVT gearbox, and IPU intelligent power unit. Among them, the engine of the hybrid system is basically the two naturally aspirated four -cylinder engines, 1.3L and 1.5L, and the motor is a three -phase ultra -thin DC brushless motor. In the middle of the box.
