Description
Technical field
This utility model relates to vehicle technology field, particularly relates to a kind of motor of electric motor car regeneration braking control system.
Background technology
Three phase electric machine is after excision power supply, the rotor of motor just can stop after rotating a period of time always due to inertia, and in reality application, many times always want to motor can position accurately or stop with the fastest speed, now it is accomplished by motor is braked, the braking method of three phase electric machine substantially has two big classes: one is mechanical braking, and two is electrodynamic；
The effect of mechanical brake device is the braking method of rapid stall after motor is cut off the electricity supply, the such as electromagnetic brake such as electromagnetic brake, electromagnetic clutch, this braking method is extensively applied under hoisting machinery or motor are in halted state, it is a little to be accurately positioned, and can prevent the unexpected power-off of motor is that weight falls voluntarily and causes the accident.Its shortcoming is if the speed of electric machine rotation is the highest, uses the most suddenly mechanical braking, is easily damaged motor, and mechanical braking mode uses the mode of friction to make motor stalls sometimes, easily makes arrestment mechanism produce bigger abrasion；
Electrodynamic is the method making motor stop rapidly to the electromagnetic torque that one, motor and actual steering are contrary while motor is cut off the electricity supply, and most common method is: regenerative braking, dynamic braking and reversing braking.
Reversing braking is the power phase changing motor stator winding while motor cuts off normal operation power supply, it is allowed to reversal trend and produces bigger braking moment and carry out braking motor, the essence of reversing braking is to make motor be intended to invert and brake, reversing braking brake force is strong, braking is rapidly, but braking poor accuracy, in braking procedure, impulsive force is strong, is easily damaged drive disk assembly.
Dynamic braking is to apply a DC source to any two-phase of stator winding while motor is cut off the electricity supply, and to produce exquisite magnetic field, relies on the inertia of rotor to rotate and cuts the method that stationary magnetic field produces braking moment.Steadily, accurately, energy expenditure is little, needs DC source, and brake force is relatively weak in dynamic braking braking.
Regenerative braking is after motor cuts off normal operation power supply, now has kinetic energy due to motor, and controller makes motor be operated in generating state, and the electric energy that motor sends can charge the battery by motor driver, by electric energy feedback to energy storage device.The advantage of regenerative braking is the kinetic energy of motor can be converted into electrical power storage can improve its utilization rate in device, and defect is the voltage and current thresholding that the voltage of regenerative braking or electric current can exceed that energy storage device, thus burns out energy storage device.
