Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motors ...

The 3/4hp induction motor on my Rockwell mill is OK, but it has a bent shaft and mismatched step pulley. I'm upgrading the motor to use a 4kW brushless hobby motor, which is roughly 5hp peak.

Let’s face it—seeing a good tool go to waste is heartbreaking. So when his cordless drill’s motor gave up after some unfortunate exposure to the elements, [Chaz] wasn’t about to bin it. Instead, he ...

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 ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

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- ...
