Embodiment
(embodiment 1)
See Fig. 1, the power drill motor speed-regulating switch circuit of the present embodiment, including the first bipolarity Hall switch 1, switching molding
Block 2, the second bipolarity Hall switch 3, rotating module 4, linear Hall switch 5, speed adjusting module 6 and battery 7.
The input of the output end connecting valve module 2 of first bipolarity Hall switch 1.The output end of switch module 2 connects
Connect the power supply circuit of the second bipolarity Hall switch 3, rotating module 4, linear Hall switch 5 and speed adjusting module 6.Second is bipolar
Property Hall switch 3 output end connection rotating module 4 first input end.The second input connection of rotating module 4 is adjusted
The output end of fast module 6, two output ends of rotating module 4 are connected with power drill motor 8.Linear Hall switch 5 it is defeated
Go out the input of end connection speed adjusting module 6.Battery 7 is bipolar Hall switch 1, switch module 2, the second bipolarity Hall are opened
3, rotating module 4, linear Hall switch 5 and speed adjusting module 6 is closed to power.
First bipolarity Hall switch 1 and the second bipolarity Hall switch 3 are switched using bipolarity latch Hall, type
Number it is DH41F.The model S49E of linear Hall switch 5.Speed adjusting module 6 uses Pwm controller, model
TL494.Linear Hall switch 5 can realize the linear change of output voltage, Pwm controller according to the size in magnetic field
Receive the voltage of linear change, PWM DC voltage is exported after amplifying by internal circuit modulation rectification, so as to control power drill
Rotating speed.Pass through linear Hall switch 5 and the collective effect of speed adjusting module 6, it is possible to achieve power drill rotating speed 0-2000rmp is electrodeless
