We know that the rated rotational speed of an industrial motor is based on two fixed factors: the number of poles and the supply frequency. So if you install a 4-pole, 480V motor in a 480V, 60Hz ...

The worst thing about a volume knob is that, having connected it to a computer, it might be wrong: if you’ve manually altered the volume settings somewhere else, the knob’s reading won’t be correct.

Whether you're a motor designer/builder or buyer/user, understanding how the efficiency of brushless DC motors is improved with the use of Hall-effect sensors is important to your building and/or ...

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 ...

Members can download this article in PDF format. At one time, designing products with motors was relatively easy. Brushed dc motors and single-phase ac induction motors didn’t require a lot of extra ...
