Description
Technical field
The utility model electric motor car power motor relates to be a kind of have electric functions and an AC and DC electricity generate function the brush permanent magnet DC motor arranged.
Background technology
Be wound with direct current drive winding and AC synchronous generating winding on the armature core of electric motor car power motor, electric functions, AC and DC electricity generate function are integrated in one, but this structure cause carbon brush easy to wear, useful life is short, changes difficulty.
Summary of the invention
The utility model provides a kind of electric motor car power motor at above-mentioned deficiency, and it is integrated in one electric functions and AC and DC electricity generate function, and continual mileage is long, and is easy to maintenance.
A kind of electric motor car power motor of the utility model is realized by the following technical solutions: it has motor housing, motor permanent magnet is fixed on the motor housing inwall, device has brush holder on the end cap of motor housing, device has carbon brush on the brush holder, stage clip, armature core is fixed on the motor shaft, coil windings is wound on the armature core, coil windings comprises the direct current drive winding, AC synchronous generating winding, engine commutator is by commutator segment, the power supply copper ring is formed, the motor commutation apparatus at the motor housing internal fixation on armature core, power supply copper ring device is at the side of commutator segment, be provided with the carbon brush conveying end with the stage clip corresponding position on the end cap, the carbon brush conveying end is sealed by closeouts.
When the power supply copper ring is the single supply copper ring, can install any side at commutator segment; When the power supply copper ring was divided into positive and negative power supply copper ring, positive and negative power supply copper ring can install in the commutator segment both sides or install simultaneously at the either side of commutator segment or the device back side at commutator segment; Described permanent magnet is fixed on the inwall of motor housing by the permanent magnet magnetic guiding loop; Described motor housing can directly adopt electric vehicle hub; Between positive and negative power supply copper ring and commutator segment and commutator segment each other device insulating barrier is arranged.
Electric motor car power motor operation principle is: this motor is when being used as power motor, and battery feed imports commutator segment by positive and negative power supply copper ring and carbon brush respectively, electric current is provided for the motor powered winding, makes motor housing (wheel hub) rotation, and electric motor car is advanced.This moment alternative electric generation winding synchronous generator.When electric motor car when cruising medium velocity controller returns zero, motor powered winding no-voltage, electric current input, electric motor car slides voluntarily, motor housing (wheel hub) continues rotation, the reverse pumping of motor powered winding goes out direct voltage, be wound on alternative electric generation winding output AC voltage on the armature through nonshared control unit, it is additional to electromobile battery to regulate the back through rectification again.When bicycle use is made in electric motor car, pedal electric vehicle advances, drive motor housing (wheel hub) rotation, the reverse pumping of motor powered winding goes out direct voltage, be wound on alternative electric generation winding output AC voltage on the armature through nonshared control unit, regulate the back to the electromobile battery charging through rectification again, also connect with the direct voltage that electronic winding reverse pumping goes out behind the ac voltage rectifier that the alternative electric generation winding can be exported and after voltage stabilizing, charge to electromobile battery.
A kind of electric motor car power motor armature winding comprises direct current drive winding and AC synchronous generating winding, two groups of winding techniques are on same armature core, armature core is made stator, motor housing (wheel hub) is made rotor, and device has commutator, electric functions, AC and DC electricity generate function can be integrated in one, separate during work, do not disturb mutually, the energy energy savings has improved continuous distance travelled simultaneously.The utility model end cap is provided with the carbon brush conveying end, after the carbon brush wearing and tearing, can take out closeouts, opens the carbon brush conveying end, takes out stage clip and carbon brush and changes, and is easy to maintenance.When adopting the single supply copper ring, can effectively reduce production costs.
