What is steps per revolution in stepper motor?

2023-02-23 13:44:09

Stepper motors are electric motors that are designed to rotate in precise increments, or steps, rather than continuously. These motors are widely used in a variety of applications, including CNC routers, 3D printers, and other precision machines. One important characteristic of stepper motors is the number of steps per revolution, which determines the precision and resolution of the motor's movement. In this article, we will explain the concept of steps per revolution and how it relates to the operation of stepper motors.

So, what exactly is steps per revolution? Steps per revolution is a measure of the number of discrete steps that a stepper motor can take in one full rotation of the rotor. For example, a stepper motor with 200 steps per revolution will take 200 steps to rotate the rotor 360 degrees. The steps per revolution of a stepper motor is determined by the design of the motor and the specific application it is being used for.

The steps per revolution of a stepper motor determines the precision and resolution of the motor's movement. The more steps per revolution, the finer the resolution and the more precise the motor's movement will be. For example, a stepper motor with 200 steps per revolution will be able to position the rotor with greater precision than a motor with 100 steps per revolution.

So why is steps per revolution important in stepper motor operation? In many applications, the precise positioning of the rotor is critical. For example, in a CNC router, the rotor must be able to move in small, precise increments to cut intricate shapes and patterns. In a 3D printer, the rotor must be able to move with high precision to lay down thin layers of material. The steps per revolution of a stepper motor determines the level of precision and resolution that is possible, so it is an important factor to consider when selecting a motor for a specific application.

In conclusion, steps per revolution is a measure of the number of discrete steps that a stepper motor can take in one full rotation of the rotor. The steps per revolution of a stepper motor determines the precision and resolution of the motor's movement, and it is an important factor to consider when selecting a motor for a specific application. By understanding the concept of steps per revolution, you can choose the right stepper motor for your application and ensure that it operates with the desired level of precision and resolution.
