Commutation replaces traditional mechanical commutation, reliable performance, forever low without abrasion, failure rate, and the service life improves about 6 than brush motor
Times, it ensure that the service life of luggage truck power resources.As shown in Fig. 2, motor-drive circuit 3 is mainly by driving chip and metal-oxide-semiconductor etc.
Peripheral circuit composition, the Hall sensor of brushless motor is connected by master controller 1, is detected by the Hall sensor of brushless motor
To the position of rotor, further according to detecting that the position of rotor sends corresponding signal to driving chip to be turned on or off phase
The metal-oxide-semiconductor circuit answered, by control the turn-on time of upper and lower bridge arm of each phase can control electric current in every phase and voltage from
And achieve the purpose that control motor.Three metal-oxide-semiconductor Q above1、Q3And Q5Respectively it is referred to as bridge arm, and following three Q6、Q4With
Q2It is referred to as lower bridge arm, when metal-oxide-semiconductor conducting, electric current flows through the armature of brshless DC motor, the current direction and magnetic flowed through
Field direction is at 90 degree, thus the original magnetic field phase separation in magnetic field and brushless direct current motor inside generated by electrical-coil,
Motor rotation is pushed, but this can not be rotated down always.Therefore, it just needs to change when motor rotates a certain angle
The turn-on sequence of metal-oxide-semiconductor continues to make hot-wire coil and fixed-field at 90 degree.The metal-oxide-semiconductor be connected under normal conditions is one group of bridge arm
Upper bridge arm and another set lower bridge arm, but cannot absolutely simultaneously turn on two bridge arms up and down of one group of bridge arm.Because this
Sample can make power supply short circuit occur, burn out component.
As shown in figure 3, luggage truck energization starts to start, self-test is carried out to drive part circuit in start-up course, if detection
To the abnormal then warning note of drive part circuit, otherwise self-test passes through and carries out self-test to the control handle of luggage truck, if hand
Handle is in abnormal condition then warning note, and otherwise normally then system starting is finished in waiting operation shape operation handle state
State.User the luggage that carries will be needed to put after can operating control handle transport, system is controlled during traveling
System reads handle data operated by user in real time and judges whether it is effective operation, if effective operation, then in driving motor
Environment evaluation is carried out before, and the highest travel speed of luggage truck is limited if there is barrier in direction of travel 2.5m and is prompted,
If there is barrier in 1.5m warning note and stop advance until Environmental security, if environment is determined as safety, will obtain
The handle operation data got carries out calculation process in the processor to which motor control order to be transferred to the electricity of drive part
Road drives luggage truck to advance.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
