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 ...

If you’re an active shopper on RC websites, you’ll find tiny motors spec’ed at hundreds of watts while weighing just a few grams, like this one. Sadly, their complementary motor controllers are ...

In a DC motor, the stator is a permanent magnet and the rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by ...

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 ...

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.

Overview of the different components of brushless DC (BLDC) motor control from position control to PWM switching. Differences between torque, velocity, and position-control ICs for BLDC motors, and ...

Brushless DC (BLDC) motors are widely used in medical devices due to their high reliability, high efficiency, low maintenance and many other advantages. One of the most popular applications is a sleep ...

Electronic enthusiasts, developers and makers searching for a modular sensorless BLDC motor controller, may be interested in a new piece of hardware created by Igor Chekhovtsov and this week launched ...
