There are many products with built-in motors around us, such as air conditioners, vacuum cleaners, and electric fans. As robots, drones, and electric vehicles, which are expected to make a big change ...

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 ...

How brushless DC motors use electronic commutation to maximize efficiency and ensure smooth and stable motion. Compare trapezoidal, sinusoidal, and sensorless commutation techniques, including key ...

A robotic manipulator is programmable on three or more axes that specify the movements of a robot, either the robotic arms or body. These robotic manipulators are automatically controlled and ...

In this article, I’ll dig into a couple of things you need to know when it comes to using salvaged hard disc drive spindle motors. Most electronics hobbyists think that such hard disc drive spindle ...

More power, torque, smarts, and battery life.

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.
