Difference between stepper motor and speed-regulating motor

1. What are stepper motors and speed-controlled motors?
A stepper motor is a motor that outputs speed and angle. It controls the position and speed of the rotor by continuously switching the circuit. The rotation step length of a stepper motor is fixed, and it is usually used in situations where position and speed need to be controlled, such as CNC machine tools, 3D printers, etc.
A speed-controlled motor is a motor that can automatically adjust the speed according to load requirements. It controls the motor speed through devices such as frequency converters and speed regulators. Speed-controlled motors are usually used in situations where the speed needs to be automatically adjusted, such as fans, water pumps, etc.
2. What is the difference between the control methods of the two motors?
The control method of the stepper motor is to continuously switch the circuit so that the motor rotor rotates according to a fixed step length. Therefore, the control accuracy of the stepper motor is very high, but the speed cannot be automatically adjusted.
The control method of the speed-controlled motor is to control the voltage and frequency of the motor through devices such as frequency converters and speed regulators, so as to achieve automatic speed adjustment. Therefore, the control accuracy of the speed-controlled motor is relatively low, but the speed can be automatically adjusted according to load requirements.
3. What are the differences in the application scenarios of the two motors?
Stepper motors are usually used in situations where position and speed need to be controlled, such as CNC machine tools, 3D printers, etc. Speed-regulating motors are usually used in situations where speed needs to be automatically adjusted, such as fans, water pumps, etc.
4. What are the differences between the advantages and disadvantages of the two motors?
The advantage of stepper motors is that they can control position and speed, but the disadvantage is that they cannot automatically adjust the speed. The advantage of speed-regulating motors is that they can automatically adjust the speed, but the disadvantage is that the control accuracy is relatively low.
5. What is the difference in price between the two motors?
Since stepper motors need to control position and speed, the technical requirements of their controllers and drivers are relatively high, and the price is also relatively expensive. The controller and driver of speed-regulating motors are relatively simple and the price is relatively cheap.
Stepper motors and speed-regulating motors are two different motors with different control methods, application scenarios, advantages and disadvantages, and prices. The choice of motor should be based on specific needs and occasions.
