We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more appliances which we make use of, are operated by DC. This is a project used to control ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can ...

The TC665 is an SMBus PWM fan speed controller with fan fault detection intended for use with brushless DC motors. This device permits temperature proportional speed control and therefore accomplishes ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

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, ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Motors are everywhere—from air conditioners and vacuum cleaners to power tools and industrial equipment. As globalisation and ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

Aerotech’s XC4 PWM digital drive is a single-axis motor drive designed for brushless DC, brush DC, voice coil, and stepper motors at up to 340 VDC operating voltage and 30 A peak current. All versions ...

1. Field-oriented control (FOC), also known as vector control, maintains a constant stator field in quadrature with the rotor field irrespective of any bandwidth limitations presented by the PI ...
