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 ...

The motor and motor control markets are thriving in a number of areas, particularly medical and robotic applications. Also, there is a rich demand for small, efficient, high- and low-torque, and high- ...

Where K'EOO is the peak value of the back-emf waveform, measured phase-to-phase (o- o). Since in metric, the voltage constant KE (volt/radian/second) equals the torque constant KT (N-m/amps), the ...

We may receive a commission on purchases made from links. People looking to get the best performance out of their tools typically gravitate toward brushless motors as those are typically more durable ...

In the world of power tools, brushless motors are all the rage. While the technology isn't exactly new, it has gained traction in recent years due to some high-profile releases by Makita, Milwaukee, ...

The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

Hard drives work by spinning platters full of magnetized data while a read/write head very quickly harvests or changes bits as needed. Older (or perhaps cheaper) drives spin at 5400 RPM, better drives ...
