motor drive control ( 控制) Device

flow snack car motor drive control ( 控制) Device for electric vehicle speed and direction of the transformation Settings, such as its function is to control ( 控制) The motor voltage or current ( 电子流) , complete control of the driving torque of the motor and the direction of rotation ( 控制) 。

early electric cars, dc motor speed control using concatenated resistance or change motor magnetic field ( Definition: transfer physical interaction between magnetic field) Coil ( 绕组) The number of turns. Because of its speed is a stage, and will produce additional energy consumption ( consume) Or use the motor structure is complex, is now rarely used. Widely used, 广泛) The crystal brake ( zhá) Dc chopper flow pipe, through the uniform ( jūn yún) To change the terminal voltage of the motor, the control ( 控制) The current of the motor ( 电子流) To realize the stepless speed of the motor. In the continuous development of electronic power technology, it also gradually by other power transistor ( The GT

O, MOSFE

T, BTR and IGBT, etc. ) Chopper control device to be replaced. From the perspective of the development of technology, with the application of new type of drive motor, electric vehicle speed control ( 控制) Is transformed into the dc inverter technology application, will become the inevitable trend, 趋势) 。

in the drive motor rotate to transform control ( 控制) Relying on the contactor, dc motor, contactor) Change the armature or magnetic field ( Definition: transfer physical interaction between magnetic field) The current ( 电子流) Direction, realize the motor rotate to transform, which makes the circuit complexity, reliability ( 减少) 。 When driven by ac asynchronous motor, the motor to change need to transform the phase sequence of three-phase ac current magnetic field, can make the control circuit is simplified. In addition, the use of ac motor and the inverter ( 变频) Speed control technology, makes the control of the electric car braking energy recycling more convenient, more simple control circuit.

transmission, 传输) Device

the electric car transmission, 传输) Device is used to pass the driving torque of motor to automobile drive shaft, when the use of electric wheel drive, most parts of transmission device can often be ignored. Because the motor start on load, so the electric car without traditional internal combustion engine automobile clutch ( 离合器) 。 Because of the driving motor can rotate to control electric circuit, 控制) Realize the transformation, so the electric car auto transmission of reverse without internal combustion engine. When using motor stepless speed control, electric vehicles can be ignored the traditional car transmission. In the use of electric wheel drive, the electric car can also omit the traditional internal combustion engine vehicle drive system differential.
