AVR360: Step Motor Controller
This application note describes how to implement a compact size and high-speed interrupt driven step motor controller. Step motors are typically used in applications like camera zoom/film feeder, fax machines, printers, copying machines, paper feeders/ sorters and disk drives. The high performance

The Proper Kind Of DC Brushless Motor Controller
When making a DC brushless motor controller choice, there are several issues that have to be addressed so that the proper device is selected for a system. If the application is a simple fan or blower, a rather simple speed controller with just an over-current limit is all that may be necessary

More Controllers, Fewer Cables
, and allow interpolated movements between different stages. The bus interface, in turn, connects to the motor, encoder, and sensors through short, stationary cables. The bus interface is Controller Area Network (CAN) technology developed in 1983 for the automotive industry. CAN now also serves a broad range
