Related Calculations: In this example, the braking torque was obtained by
connecting a dc source to one phase of the motor after it is disconnected from the lines (Fig. 4a). With solid-state electronics, the problem of a separate dc source has been solved economically. The braking torque is low at the higher initial speed and increases to a high peak value as the motor decelerates; however, it drops rapidly to zero speed (Fig. 4b). The losses are approximately the same as that for a single start. Higher braking torque can be obtained by using higher values of dc voltage and by inserting external resistance in the rotor circuit for a wound-rotor motor.
Approximately 150 percent rated current (dc) is required to produce an average
braking torque of 100 percent starting torque.

Cálculos relacionados: Neste exemplo, o binário de frenagem foi obtido através
da ligação de uma corrente contínua a uma das fases do motor, com este
desligado da corrente de alimentação (Fig. 4a). Com a utilização de sistemas
electrónicos de estado sólido, o problema de dispor de uma fonte de alimentação de corrente contínua independente foi solucionado de forma económica. O binário de frenagem é reduzido durante a fase de maior velocidade inicial e aumenta até
ao seu máximo valor, à medida que o motor desacelera; no entanto, o binário cai rapidamente, quando a velocidade do motor se aproxima do zero (Fig. 4b). As
perdas são aproximadamente as mesmas verificadas num único arranque. No caso
de motores de rotor bobinado, podem ser obtidos binários de frenagem mais elevados através da utilização de correntes contínuas de tensão mais elevada e da introdução de uma resistência externa no circuito do rotor. Para a obtenção de um binário de frenagem médio igual a 100% do binário de arranque, é necessário uma corrente contínua com uma intensidade igual a 150% da intensidade nominal.
