Abstract

A control for an electromagnetic holding brake with a coil for releasing the holding brake and maintaining it in the released position, which requires a minimum brake coil voltage to maintain it in the released position, having a DC-DC converter with an input and an output, the DC-DC converter being designed to convert a variable input voltage pre-sent at the input into a predetermined switch-on voltage provided at the output and a predetermined holding voltage provided at the output, the holding voltage corresponding to the minimum brake coil voltage, the DC-DC converter being designed to implement a 2-stage voltage control and, in a first stage, to maintain the switch-on voltage as a regulated DC voltage for a predetermined time, to downregulate the voltage from the switch-on voltage following a predetermined voltage curve to the holding voltage as regulated DC voltage, and to maintain it in a second stage.

Description

technical field [0001] The invention relates to a control device for an electromagnetic holding brake, an electric motor with an electromagnetic holding brake controlled by such a control device, and a method for controlling an electromagnetic holding brake with such a control device . Background technique [0002] Various safety brakes with corresponding control devices are known from the prior art. The task of safety brakes is usually to brake moving substances or loads from motion or to hold them safely at rest. The braking torque or braking force is usually produced by a preloaded spring. In the prior art, safety brakes are generally used as holding brakes and are generally not designed to brake movement, but only to hold substances at rest. In most cases, the regulated drive takes over the braking of the movement, so safety brakes or holding brakes are usually also designed for emergency braking. [0003] Therefore, in normal operation, the holding brake only needs ...
