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 ...

This application note presents BLDC motor control using sensor sinusoidal PWM modulation with Z32F128 microcontroller. It also discusses ways on how to implement sinusoidal PWM modulation and ...

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 ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

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, ...

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 ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...
