The most basic definition of a stepper motor is an electromechanical device that converts electrical energy into mechanical energy. Specifically, it is a brushless motor that can divide the entire rotation into equal steps, and when adjusting the motor according to the size of the application, it can be precisely controlled without a feedback mechanism.
The main types of stepping motors include permanent magnet stepping motors, variable reluctance stepping motors and hybrid synchronous stepping motors. Although the operations of these three methods are different, they all have many advantages over their servo motors in some applications.
The advantage of stepper motors:
Not every application will benefit from a stepper motor, but a stepper motor may be the ideal choice in the right environment. First, the stepper motor has full torque when it is stationary, and the rotation angle of the motor is proportional to the input pulse. Essentially, stepper motors have excellent speed control, precise positioning and repeatability of motion.
In addition, since there are no contact brushes in the motor, the stepping motor has high reliability. This can minimize mechanical failures and maximize the service life of the motor. Since the speed is proportional to the frequency of the pulse input, many different rotation speeds can be achieved, so these motors can be used in a wide range of environments.
The application of stepper motor
There are many uses for stepper motors, but the most common ones include:3D printing equipment, textile machines, printing machines, medical imaging machinery, small robots, CNC milling machines, welding equipment.
Although these applications are the most common, they are only a small part of what stepper motors can use. Generally speaking, any application that requires high-precision positioning, speed control and low-speed torque can benefit from the use of stepper motors.
Servo motors have a place in the industry and have many advantages, and stepper motors are an ideal solution for many applications. Stepper motors are a powerful motion control technology that can be found in many common machines and equipment.
