Abstract

A direct current dynamo control apparatus of electromobile with sensor but brush built-in analogue/digital converter, pertains to the application of single chip computer in the domain of direct current dynamo control. It includes a single chip computer with A/D converter and a rotor magnet steel address sensor. It is characterized in that the single chip computer is connected to the rotor magnet steel address sensor, reversed door circuit and discharge circuit respectively. Commutating control realizes by detecting three rotor magnet steel address sensor information provided by Hall element via the single chip computer; controlling start current realizes by controlling the output level of discharge circuit; controlling rotation rate realizes by controlling transmission voltage of the built-in analogue/digital converter. The invention can control various types of brushless direct current motor with a plurality of interfaces that can be functional expanded, which overcomes the shortcomings of high cost, bad compatibility and unable to expand function of external analogue/digital converter, application-specific integrated circuits controller. It can be used for controlling commutate, rotation rate and start current in various types of electromobile with Hall sensor.

Description

The electric vehicle brushless DC motor with sensor control setup of built-in D/A converter
Technical field the invention belongs to singlechip technology in the DC MOTOR CONTROL Application for Field.
Before background technology the invention applying date, special IC is adopted in the control of attached brushless DC motor of electric vehicle, but has the cost height, the defective that capacitive difference and function can't be expanded.
Certainly the electric vehicle brushless DC motor with sensor control setup that provides a kind of built-in D/A converter of summary of the invention the invention.
The invention solves the technical scheme that its technical matters adopts: comprise micro controller system, the rotor magnetic steel position transduser of being with A/D converter; Micro controller system is connected with rotor magnetic steel position transduser, reverse gate circuit and discharge circuit respectively, commutation, speed governing and the current limliting of control brushless direct current motor.Input port is used to measure the signal from the rotor magnetic steel position transduser; The rotor magnetic steel position sensor signal of three band Hall elements is connected with the single-chip processor i/o input end respectively; The single-chip processor i/o mouth is connected with discharge circuit with the reverse gate circuit respectively, and the mouth of reverse gate circuit is connected with the control end of 6 power respectively, and built-in A/D converter is connected with the op amp input end.The state of the rotor magnetic steel position sensor signal of three band Hall elements and the relation between 6 power tube conductings are left among the EPROM of micro controller system with tabulated form.Whether micro controller system is controlled the power tube conducting by the output control word by detection rotor magnet steel position sensor signal.
The beneficial effect of the invention is: the invention realizes the control to all kinds of brshless DC motors, and leave a plurality of interfaces for function expansion, overcome the defective that external A/D converter, special IC controller cost height, poor compatibility, function can't be expanded.Be widely used in the control of commutation, rotating speed and starting current of the brshless DC motor of all kinds of battery-driven car band Hall elements.
Appended drawings 1 is the electrical schematic diagram of the invention.
The specific embodiment is consulted Fig. 1.The invention micro controller system adopts U.S. MICROCHIP company 8-bit microcontroller, and present embodiment adopts the micro controller system PIC16C711 of built-in four road A/D modular converters.Delivery port comprises I/O (1), I/O (2), I/O (3), I/O (4), I/O (5), I/O (6), and the input end with 7406 reverse gate circuit is connected respectively.7406 mouth is six MOSFET power tube VF respectively 1, VF 2, VF 3, VF 4, VF 5, VF 6Control end be connected; Input port comprises I/O (7), I/O (8), I/O (9), respectively with three rotor magnetic steel position sensor signal H of the counter electromotive force of taking from the motor stator winding 1, H 2, H 3Be connected.Delivery port comprises that I/O (10) is connected with an input end of LM324 op amp by resistance.An input end of LM324 op amp passes through resistance eutral grounding.The invention is by three rotor magnetic steel position sensor signal H of the counter electromotive force of detection motor stator winding 1, H 2, H 3, and by i.e. three the rotor magnetic steel position sensor signal H of the commutation table among the EPROM that leaves micro controller system with tabulated form in 1, H 2, H 3State and 6 power tube VF 1, VF 2, VF 3, VF 4, VF 5, VF 6Relation between the conducting, by the control word that delivery port is sent, difference conducting VF 1, VF 2VF 2, VF 3VF 3, VF 4VF 4, VF 5VF 5, VF 6VF 6, VF 1Promptly realize the commutation of brshless DC motor.In the process of the normal operation of brshless DC motor, by controlling the output voltage of built-in D/A, i.e. the electric current of may command brshless DC motor, and then control rotating speed of motor.Micro controller system calculates rotating speed of motor by taking from the cycle of motor stator winding back-emf signal, and it with given rotating speed relatively, as be higher than given rotating speed, and then reduce output numerical value, reduce the electric current of motor, reduce its rotating speed to reach.
