Further described, the transistor Q4 and the transistor Q5 are N-type MOSFET transistors.
It should be noted that, the motor speed regulation chip U6 is a half-bridge gate driving circuit integrated circuit chip, and is used for driving the N-type power MOSFET transistors Q4 and Q5 electrically connected to the high side HO and the low side LO respectively.
Specifically, a PWM signal with a frequency of more than 20KHZ is input from the pwm_pls1 end, when the signal is high, the triode Q4 is turned on, the triode Q5 is turned off, and +24v_mot output by the rectifying and filtering module is filtered by the triode Q4 through the inductor L4 and the polar capacitor C42 and output to the motor; when the signal is at a low level, the triode Q5 is conducted, the triode Q4 is closed, the +24V_MOT output by the rectifying and filtering module is disconnected, and the current of the inductor L4 is reversely output to the motor through the continuous current of the triode Q5 and the filtering of the polar capacitor C42.
This is because the characteristic that the current of the inductor L4 can only gradually rise and fall but cannot be suddenly changed realizes the voltage regulation, and the larger the signal duty ratio is, the higher the output voltage is, thereby realizing the speed regulation.
To further illustrate, the forward and reverse rotation driving module includes a relay K1, a relay K2, a driving chip D4, an inductor L25, a capacitor C68, and a connector J3;
the model of the driving chip D4 is DB107, and the connector J3 is used for being electrically connected with the motor;
the 1 end of the relay K1, one end of the inductor L25 and the 2 end of the connector J3 are electrically connected with the 1 end of the driving chip D4, the other end of the inductor L25 is electrically connected with one end of the capacitor C68, the 1 end of the relay K2, the other end of the capacitor C68 and the 3 end of the connector J3 are electrically connected with the 3 end of the driving chip D4, and the 2 end of the driving chip D4 is electrically connected with the rectifying and filtering module;
the 2 ends of the relay K1, the 2 ends of the relay K2 and the 4 ends of the driving chip D4 are all grounded, the 3 ends of the relay K1 and the 3 ends of the relay K2 are all electrically connected with the motor speed regulating module, the 4 ends of the relay K1 and the 4 ends of the relay K2 are all electrically connected with the BDOUT ends of an external power supply, and the 5 ends of the relay K1 and the 5 ends of the relay K2 are all connected with 12V working voltage.
It should be noted that, the BDOUT terminal of the external power supply provides the working power supply for the relay.
Specifically, when the relay K1 is electrically connected, i.e., the 1 end and the 3 end of the relay K1 are electrically connected, and the relay K2 is not operated, i.e., the 1 end and the 2 end of the relay K2 are electrically connected, the power supply of the motor speed regulating module is conveyed to the motor from the drive_back end, i.e., the 3 end to the 1 end of the relay K1, and the power supply passes through the normally closed end, i.e., the 1 end to the 2 end, i.e., the power supply cathode, of the relay K2, thereby realizing the forward rotation of the motor.
When the relay K2 is electrically operated, namely the 1 end and the 3 end of the relay K2 are electrically connected, and the relay K1 does not act, namely the 1 end and the 2 end of the relay K1 are electrically connected, the power supply of the motor speed regulating module is conveyed to the motor from the DRIVER_BACK end, namely the 3 end to the 1 end of the relay K2, and the power supply passes through the normally-closed end, namely the 1 end to the 2 end, namely the power supply cathode of the relay K1, so that the motor reverse rotation is realized.
When the relay K1 and the relay K2 do not act, the 1 end and the 2 end of the relay K1 and the 1 end of the relay K2 are electrically connected, so that the 2 end of the connector J3 electrically connected with the motor is grounded, and the motor brake is enabled to be motionless.
Further, the driving chip D4 is configured to freewheel the reverse current and absorb the high voltage generated when the motor is stopped.
