Motors: what is a brake resistor, and what is it used for?

Adriana Glazer | 6. August 2021

Electric motors sometimes need a brake resistor. But what does the brake resistor do, and what advantages does it offer? Since a motor’s design is similar to a generator’s, motors always generate voltage. This is counterintuitive, since motors actually use electrical power to generate mechanical (rotor) movement, but it is a fundamental principle of electrical […]
