NEWS: Rotero has a new supplier
At ROTERO, we offer an extensive range of stepper motor drivers, designed to provide optimal control and efficiency in drives and industrial processes.
A stepper motor driver, also known as a stepper motor amplifier, is an electronic device that supplies current and voltage to the stepper motor, allowing it to be controlled precisely. The driver receives pulse signals from a controller and converts them into a power signal that moves the stepper motor. Each pulse received by the driver corresponds to an angular rotation, ensuring controlled and repeatable positioning.
Various types of stepper motor driver are available, each designed for specific applications. The standard drives often feature microstepping settings and receive a pulse and direction signal that controls the rotational speed, position and acceleration in an open-loop system. The advanced drivers often incorporate closed-loop control via a feedback encoder signal. This enables torque and position control. These drives often also offer communication protocols, such as EtherCAT and CANopen, making them suitable for industrial applications.
One of the key features of a simple stepper motor driver is open-loop position control without encoder feedback. Closed-loop systems do incorporate encoder feedback and are often equipped with bus–communication. The encoder feedback also allows torque control.
Stepper motor drivers are used in a wide range of applications where precise position and speed control are required. In 3D printers, stepper motor drivers play a crucial role in moving the print head, enabling it to lay down the layers of the printed object with high precision.
