Autonics Stepper Motors


Autonics stepper motors are precision-engineered electromechanical devices designed to convert electrical pulses into precise mechanical motion. These motors offer accurate positioning and control capabilities, making them ideal for applications that require precise and repeatable movement.

Autonics stepper motors consist of a rotor and stator arrangement. The rotor is a permanent magnet, while the stator contains multiple sets of electromagnetic coils. When electrical pulses are applied to the coils in a specific sequence, a magnetic field is generated, causing the rotor to move in a step-wise manner. The number of steps per revolution determines the motor's resolution.

One of the key advantages of Autonics stepper motors is their ability to achieve precise positioning. By controlling the number of pulses applied to the motor, it can be accurately moved to a desired position or angle. This level of control makes them well-suited for applications such as robotics, CNC machines, 3D printers, and automated equipment.

Autonics stepper motors offer various features and options to meet specific application requirements. These may include different step angles, torque ratings, holding torque capabilities, and shaft configurations. Some models may also incorporate additional features like built-in encoders for improved position feedback.

Autonics stepper motors are known for their reliability, durability, and long lifespan. They are designed to withstand demanding operating conditions and provide consistent performance over extended periods. Additionally, they are generally easy to integrate and control, thanks to their compatibility with standard motor drive systems and interfaces.
