Melexis has introduced a 40W driver with four half bridges and field-oriented control to operate three-phase brushless motors and four-wire stepper motors. A CPU is included and both sensor-less and ...

Variable-speed drives for three-phase motors are ubiquitous components of industrial systems that help save energy and optimize performance. Traditional, scalar control techniques for variable-speed ...

With the new InstaSPIN™-FOC (field-oriented-control) solution from Texas Instruments Incorporated (TI) designers can identify, tune and fully control (through variable speeds and loads) any type of ...

This application note presents the Field Oriented Control (FOC) of a 3-phase AC induction motors. It demonstrates the use of Zilog’s Z16FMC ZNEO! 16-bit microcontroller to implement Vector Control of ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Texas Instruments has optimised a pair of DSPs for field-oriented motor control in domestic appliances such as washing machines, vacuum cleaners and lawn mowers. “Their capabilities, including ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

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, ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
