This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Precision movement and positioning systems used in industries such as automated manufacturing using the advanced single-chip digital motion controllers announced by STMicroelectronics. Precision ...

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 ...

The 0.72° unit needs no wiring between controller, driver and motor, with no need for a pulse generator. A positioning function is built in, ensuring that the traveling amount, speed, and other ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.
