Abstract

In the case of a brake for a motor, in particular an alternating current motor with a solenoid, in order to improve the dynamic characteristics without increasing the power loss it is proposed to divide the coil of the solenoid (2) into two part coils (3, 4), by means of an intermediate tap (6), one of these two part coils being located on a freewheel circuit. <IMAGE>
