Function description
The KLIBO start brake system is designed for the direct starting and braking of cage rotor motors and single-phase motors with starting capacitors. The integrated power electronics (inverter) generate a direct current that creates a stationary magnetic field in the motor winding and brakes the rotor. The magnetic field strength and thus the braking force is determined by the magnitude of the adjustable direct current. The module allows for stepless adjustment of the braking time and the braking current. A controller manages and monitors the operating condition, ensuring safe re-engagement even during the braking process. The start relay and the brake relay are safely switched via two independent output relays. The brake relay switches the braking current to the motor winding. To achieve the maximum braking torque, the braking current can be switched over 2 or even 3 windings depending on the wiring and motor type.
Motor heating during braking operation:
The motor heating during braking due to direct current supply corresponds to the heating during motor start-up. If motors are frequently started and braked with high currents, the motor temperature should additionally be monitored by a thermistor (temperature sensor).
