Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

This file type includes high-resolution graphics and schematics when applicable. Millions of small electrical devices with built-in motor-driven mechanisms, used daily around the world, rely on ...

Sensorless control of stepper motors, in which the speed of the rotor is determined through a virtual encoder within the controller, is possible, claims German firm Nanotec. “This enables the stepper ...

The amount of noise in a motor depends on the type of motor, environmental conditions, and the specific application. Permanent magnet and hybrid stepper motors are generally quieter, as they have a ...

AMI Semiconductor, a manufacturer of integrated mixed-signal and structured digital products, has introduced two single-chip stepper motor controller ICs. AMI Semiconductor, a manufacturer of ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ever more important. When selecting a motor for an ...
