Studies on the Variation of the Process Parameters when Braking DC Motors with Shoe Brakes

摘要

The paper aims to present some studies on the influence of mechanical braking systems with shoes on separately excited DC motors, intended to change the regime speeds. The researches were carried out by braking a 5 W DC motor with a maximum speed of 700 rpm, intended for special drives, with the help of a polyamide half-shoe brake, when measuring the variation of some process parameters: speed of the motor under the braking conditions, the temperature inside the shoe and the electrical parameters of the motor - voltage, current, power and energy consumed.
