Direct current motor forward and backward rotation detection method
There are several ways to detect the positive and negative rotation of a direct current motor: 1. ** Using sensors to detect **: install one or more Hall sensors or proximity switches on the outside of the direct current motor. When the direct current motor turns, the sensors will transmit the rotation information to the processor to determine the direction of the direct current motor. 2. ** Detection by voltage comparison **: By comparing the voltage at both ends of the motor, it can determine the positive and negative rotation of the motor. 3. ** Based on special circuit detection **: - A positive and negative reversal detection circuit is adopted. The circuit includes a first circuit and a second circuit, and the two circuits are respectively provided with a one-way conducting device. The two ends of the first circuit are connected with the two ends of the direct current motor. When the direct current motor is rotating forward, the one-way conducting device of the first circuit is conducted, and when the direct current motor is rotating backward and at rest, the one-way conducting device of the first circuit is cut off. The two ends of the second circuit are also connected with the two ends of the motor. When the direct current motor is rotating backward, the one-way conducting device of the second circuit is conducted, and when the direct current motor is rotating forward and at rest, the one-way conducting device of the second circuit is cut off. - Using a circuit structure similar to the H-bridge, the current circuit was changed by controlling the on-off of different switches in the circuit (such as the H-bridge circuit consisting of a MOS tube or a triode instead of a mechanical switch), so as to realize the forward and backward rotation of the motor. The forward and backward rotation state of the motor could be judged according to the control logic of the circuit and the current flow direction. 4. ** Mechanical structure detection device **: The device is provided with an upper support seat and a lower support seat, the lower support seat is provided with a rotating linked rotating shaft, the upper end of the linked rotating shaft is provided with a loading mechanism, the lower end of the linked rotating shaft is provided with a motor shaft fixing sleeve for fixing an output shaft of a motor to be tested, a stop mechanism is arranged near the linked rotating shaft and corresponds to the loading mechanism, a sensing mechanism is arranged at one end of the upper support seat and corresponds to the loading mechanism, a display seat is extended upwards from the upper support seat, and an indicator light group which is connected with the sensing mechanism is arranged on the display seat. The rotation direction of the load bearing mechanism was used to determine the forward and backward rotation of the motor, and the sensing mechanism and the indicator light group displayed the judgment result.
