Braking Card
Braking card for single-phase and three-phase asynchronous motors.
The braking card model LBZZ15301 with the aid of two external buttons and an external contactor (not supplied), is useful for electronically driving and braking single-phase and three-phase asynchronous motors. It shows all its effectiveness when, in emergency situations, it is necessary to stop the rotation of blades, burs and tools in general in a short time, which, if left alone, could damage people or things.
The braking can be activated after each ignition or in particularly dangerous conditions such as the opening of a protective casing.
In both cases, the shutdown occurs in the shortest possible time keeping the current injected in the motor under control in order not to overheat the windings too much.
Thanks to its use, it is possible to avoid using self-braking engines with the following advantages:
- - Do not support the maintenance of abrasive discs anymore;
- - Braking time not dependent on the state of the abrasive discs;
