The electrodynamic brake type BR 380... allows for wear and tear free braking of three phase and AC asynchonous motors which is achieved by feeding a direct current onto the motor coil.
Upon expiration of the braking time, the braking operation is ended after machine has come to a standstill.
Switching the motor off will introduce the fully automatic braking cycle.

synchronized machines includes numeric control.Dynamic menu page by page and auto-learning menu make easy its use. For the machines with more than 4 axes and with graphic version we set up the programmer Cybelec, bi or tridimensional, monochromatic or with colours.
Parallelism : bending accuracy is assured by two proportional cocks controlled by CNC; they control the oil flow from the industrial cylinders and from two optical linear transductors placed on the shoulders on the gap level. Such a system, which can control step by step the ram's position and parallelism errors due to the side depth throats, make it possible to obtain the maximum parallelism accuracy.
A large series of options improve the features of this machine.ontrol |

PETER electronic has added the compact type series VersiBrake 230/400-25 L (LP) to its tried and tested product line of electronic DC brakes. The device, which features an upgraded power section designed for a rated device current of 25 A, is available either as a housing version or as a circuit-board version for rated motor currents up to 12.5 A. In preparation for the certification by the German Trade Association (Technical Committee for Wood), VersiBrake 230/400-25L (LP) already now meets the association's requirements for category 2 acc. to EN 954-1. VersiBrake 230/400-25 L (LP) features double safety protection: i.e., control via motor contactor and motor voltage detection. In addition, a surge suppressor circuit and a braking current infinitely variable between 0 and the rated device current reduces the failure probability of the braking device and thus indirectly that of the machines, too. An integrated overload monitoring function, which, if the braking frequency is too high, prevents motor restart, provides safety both for the VersiBrake and the operator. The integrated and adaptable motor standstill detection gives the user flexibility with regard to the motor types available.

The soft start and braking device of the VersiComb series from PETER electronic, for motor ratings up to 11KW, represents an alternative with a good cost-performance ratio in order to replace star-delta starting in combination with a d.c. braking device.
The devices of the VersiComb II type enable soft start and wear-free braking of three-phase asynchronous motors. Their advantages in comparison with direct-on-line starting or star-delta starting are a torque increase without jerk and current reduction during the starting phase.
This gives the mechanical system and the drive components a longer life.
