Electronic brakes are used to brake asynchronous machines in squirrel-cage design and Single-phase AC capacitor motors within 10 seconds. Therefore an adjustable DC flows through one or more windings of the motor after operating supply is switched off. This current is generated by a thyristor phase control for a fixed time. High currents are induced in the counter-field rotating squirrel cage, resulting in an accordingly high brake torque.
Protection of the brake
We equip all switches with a patended switch adapter (circuit breaker) to protect the electronic brake from short-circuits and voltage peaks particularly in the event of restarts during the braking operation.
Motor heating during brake operation
The motor heating during braking with DC correlates with the heating during motor start. If a motor is frequently started and stopped a temperatur should be mointored by a thermistor.
Adjusting brake current
The braking current depends on the motor and flywheel mass. It can be adjusted with a potentiometer. Our experience from several projects in the past shows that it is reasonable to test the motors and its flywheel mass in our development centre when production quantities warrants this additional effort to ensure the optimum adjustment of the brake. On request external adjustment of the brake can be realised for all our available switches.
We have profound experiences in braking moduls for many years. That's why we are the right partner for electronic brakes.
