Functional description:
The KLIBO-Phase-Brake module has been developed for braking cage motors and single-phase motors with starting capacitor. The integrated power electronics element generates a direct current which induces a standing magnetic field in the motor coil and brakes the rotor. The magnetic field strength (and thus the braking power) can be set through the continuously adjustable strength of the direct current. This module supports continuous adjustment of braking current and of active braking time. These are controlled via the optional SP input. Power contactors controlled by the KLIBO-Star-Delta-Module switch the KLIBO-Phase-Brake Module directly to the motor coil .
Motor heating during braking:
When braking a motor by feeding a direct current, the same amount of heat is generated as during start-up. For motors that are frequently started and braked by high currents, the additional use of a thermistor (thermal sensor) to monitor the motor temperature is recommended.
