There are many control methods of stepping motor, among which DC control method is the most commonly used.
DC control method refers to inputting DC power to the corresponding phase of stepping motor to control the rotating direction and speed of the motor.
The advantages of DC control method are simple, compact structure, high control precision and accurate displacement control.
However, the DC control method also has some shortcomings, such as poor dynamic response of the motor, inability to realize fast rotation and high power consumption of the motor.
Another commonly used control method of stepping motor is analog control method.
Analog control method refers to inputting analog signals to the corresponding phase of stepping motor to control the rotating direction and speed of the motor.
The advantages of analog control mode are that the motor has strong dynamic response ability, can realize fast rotation and has low power consumption.
However, the analog control method also has some shortcomings, such as low control accuracy and inability to achieve accurate displacement control.
In addition, there is a relatively new stepping motor control mode, namely digital control mode.
Digital control method is to point to the corresponding phase input digital signal of stepping motor to control the rotating direction and speed of the motor.
The advantages of digital control mode are high control precision, accurate displacement control, strong motor dynamic response and fast rotation speed.
However, the digital control method also has some shortcomings, such as high power consumption of the motor.
In a word, there are many control methods of stepping motor, each method has its advantages and disadvantages, and the appropriate control method should be selected according to the actual application requirements.
The control method of stepping motor can not only meet the needs of industrial automation, household appliances, medical equipment and other fields, but also meet the needs of other fields and make contributions to social development.
