Description
Technical field
The present invention relates to a kind of motor driver, specifically a kind of driver of disc type electric machine.
Background technology
Axial magnetic flux disc type electric machine has the feature of high power density and high pulling torque, is particularly suitable for carrying out electrically driven (operated) occasion at needs and applies, but does not still have comparatively special digit driver at present.Tradition permagnetic synchronous motor adopts servo-driver mostly, be not suitable for the power drive system needing to carry out speed governing repeatedly, according to the type of drive of brushless, permanently, motor has good speed adjusting performance, but the torque pulsation of motor is larger, bring the vibrations of motor and noise comparatively large, affect the overall performance of power drive system particularly electric automobile etc.Particularly when disc type electric machine adopts iron-core-free structure, because the inductance of motor is very little, the output current fluctuation of driver is very large, and noise and the traveling comfort of motor are all greatly affected, and also can shorten the useful life of power device; Therefore for the disc type electric machine of high-power axial magnetic flux, especially the disc type electric machine of iron-core-free, need special high-grade drives device, simultaneously because the power drive system of electric automobile is all progressively to digital development, be thus also badly in need of having high performance digit driver supporting with it.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has good driveability and digital interface, can be integrated in the central control system of the equipment such as electric automobile, and the driver of disc type electric machine that the independence that can realize motor speed and torque controls.
In order to solve the problems of the technologies described above, the driver of disc type electric machine of the present invention, comprises acquisition testing signal, receives control command, carries out processing to collection signal and can export the digital signal processing module of control signal; Be provided with between digital signal processing module and motor and motor rotor position and size of current and phase place detected and the photoelectric encoder and the current sensor that detect the signal obtained and pass to digital signal processing module; Also comprise one can input control order and control command is transferred to the keyboard operation module of digital signal processing module and one can receiving digital signals processing module collection signal and the collection signal received is outputted to the digital interface of host computer; Described digital interface also can receive the control signal of host computer output and control signal can be transferred to digital signal processing module; Digital signal processing module being connected with one can the power circuit of control signal that exports of receiving digital signals processing module; Power circuit is provided with and can be the electrokinetic cell that power circuit provides power supply; Power circuit output is connected to the adjustment of inductance module that can regulate electric machine operation state; Described adjustment of inductance model calling is to the control input end of motor.
After adopting above-mentioned structure, due to digital signal processing module and the system supporting with digital signal processing module of setting, effectively can reduce the motor oscillating and noise that use legacy drive to bring, improve the performance of power drive system and even electric automobile entirety, the requirement of market to the power drive system digital development of electric automobile can be met simultaneously.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the driver of disc type electric machine of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the driver of disc type electric machine of the present invention is described in further detail.
As shown in the figure, the driver of axial magnetic flux disc type electric machine of the present invention, comprise acquisition testing signal, receive control command, carry out processing to collection signal and the digital signal processing module of control signal can be exported, TMS320F2812DSP chip can be adopted as the central control chip of digital signal processing module, be provided with between digital signal processing module and motor and motor rotor position and size of current and phase place detected and the photoelectric encoder and the current sensor that detect the signal obtained and pass to digital signal processing module, also comprise one can input control order and control command is transferred to the keyboard operation module of digital signal processing module and one can receiving digital signals processing module collection signal and the collection signal received is outputted to the digital interface of host computer, digital interface also can receive the control signal of host computer output and control signal can be transferred to digital signal processing module, digital signal processing module being connected with one can the power circuit of control signal that exports of receiving digital signals processing module, power circuit is provided with one and can be the electrokinetic cell that power circuit provides power supply, power circuit is connected with can the adjustment of inductance module of voltage and current that exports of received power circuit, and described adjustment of inductance model calling is to the input of motor.
Operation principle is as follows:
First, photoelectric encoder and current sensor is adopted to detect motor rotor position and size of current and phase place, and pass to central control chip detecting the signal obtained, control chip passes through vector calculus, the rotating speed inputted according to user and torque are specified and are exported corresponding control signal to power circuit, power circuit exports powerful voltage and current, and these voltage and currents are added to the input of motor after adjustment of inductance module, thus drive motors running; Secondly, central control chip detects the running status of motor simultaneously, and testing result is delivered to host computer by digital interface, then, operation keyboard is also directly received in central control chip, keyboard has starting and stopping, acceleration, deceleration, increase moment of torsion, reduce torque button, user just can realize acceleration and deceleration to motor, increase and decrease moment and start-stop control by pressing button, and same operation also can be realized in the mode of instruction by digital interface by host computer.
