FAQ

What makes stepper motors ideal for precision positioning applications?

Stepper motors excel in precision positioning because they move in discrete, predictable steps without requiring feedback sensors for basic positioning control. Each electrical pulse corresponds to a specific angular movement, typically 1.8 degrees per step, allowing for precise positioning control. This inherent accuracy, combined with excellent holding torque when stationary, makes stepper motors perfect for applications requiring reliable and repeatable positioning without the complexity of closed-loop control systems.

How do stepper motors compare to servo motors in industrial applications?

Stepper motors offer several advantages over servo motors in specific applications, including lower cost, simpler control systems, and excellent low-speed torque characteristics. They provide precise positioning without feedback devices and maintain full torque at standstill. However, servo motors typically offer higher speeds, better efficiency at high speeds, and superior performance in dynamic applications. The choice between stepper and servo motors depends on specific application requirements including speed, torque, precision, and cost considerations.
