Manual
Function description
Electronic brakes are used to decelerate squirrel-cage induction machines and single-phase AC capacitor motors after switching off within 10 seconds. For this purpose, a controllable direct current flows through one or more windings of the motor when the operating supply is switched off. This is generated by a thyristor phase control for a preset time and is then turned off. High currents are induced in the rotating squirrel cage against the field, resulting in a correspondingly high braking torque.
Protection of the Brake
To protect the electronic brake against short circuits and voltage spikes, especially during reactivation while braking, we implement all switches with a patented switching device (pre-switch opener) developed by us.
Motor Heating During Braking
The motor heating during braking due to direct current supply corresponds to the heating occurring during motor startup. If motors are frequently started and braked, the motor temperature should additionally be monitored by a thermistor (temperature sensor).
Braking Current Adjustment
The level of the braking current depends on the motor and the flywheel mass. It can be adjusted in height at a rotary potentiometer (phase control). Experience has shown that it is advisable to test the motors with flywheel mass in our facility for larger series to achieve the optimal brake setting. Upon request, an external adjustment option can be provided in all switch series.
