The invention provides a method for preventing a motor from stalling, a motor and a steering gear, relates to the technical field of motors, and solves the technical problems that existing DC motors have defects in anti-blocking design, which easily increases hardware costs or reduces product stability. The method includes the following steps: S1: monitor the battery voltage during the working process of the motor, and obtain the original voltage monitoring signal through the ADC module; S2: perform notch and filter processing on the original voltage monitoring signal to obtain the processed voltage Monitoring signal; S3: Calculate the first-order differential of the processed voltage monitoring signal to obtain the first-order differential curve of the voltage monitoring signal; S4: Calculate and judge the differential value of the first-order differential curve to obtain the judgment of motor stall . The present invention can accurately and timely capture the time point of motor stalling, does not need a travel switch, can reduce structural requirements, makes the product portable and miniaturized, and realizes a low-cost and stable solution to motor stalling.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a method for preventing a motor from stalling, a motor and a steering gear. Background technique [0002] A motor refers to a device that can convert electrical energy into mechanical energy. It has the characteristics of simple structure, convenient control, small size, high efficiency, variable power, and no pollution. Motors are divided into DC motors and AC motors according to the type of working power supply. Among them, DC motors are motors that convert DC electric energy into mechanical energy. They have a wide range of applications, such as electric toy cars, electric shavers, electronic door locks, electronic padlocks, and electronic luggage locks. Wait. When the DC motor is rotating, no external force is allowed to forcibly stop the motor from rotating. If the motor is blocked for a long time, it is easy to burn the DC motor, power supply and motor drive circuit. At the...
