Function description
The KLIBO phase brake module is designed for decelerating cage rotor motors and single-phase motors with start capacitors. The integrated power electronics generate a direct current that creates a stationary magnetic field in the motor winding, thereby braking the rotor. The strength of the magnetic field, and thus the braking force, is determined by the magnitude of the continuously adjustable direct current. The module allows for the continuous adjustment of the braking current as well as the active braking time, which can be controlled via the SP input (optional). The KLIBO phase brake module is directly switched to the motor winding via contactors, which are controlled by the KLIBO star-delta module.
Motor Heating During Braking Operation
The motor heating during braking by direct current supply corresponds to the heating during motor start. If motors are frequently started and braked with high currents, the motor temperature should additionally be monitored by a thermistor (temperature sensor).
