Machine tools

Few sectors cover such a broad spectrum as mechanical tool building – with regard to materials, forms and technologies. Almost all applications stand out for their absolute precision and ever-increasing production speeds.

FRIZLEN resistors are therefore used as braking resistors in combination with the frequency converter and in the power supply of machines.

Secure emergency off function

To implement a machine's emergency stop function, three-phase braking resistors are often used. These braking resistors work in direct combination with the motor. Therefore, the resistor is connected to a contactor in the three-phase circuit of the motor.

The motor windings are therefore short-circuited in a controlled manner using resistors. The objective of this extremely robust switch is to ensure braking action independent of the chopper unit of the DC intermediate circuit.

Administer controlled braking to slow down movement

In operating conditions in which the motor acts as a generator (e.g. when lowering or braking), the generated energy must be discharged. This energy can be discharged by a chopper resistor or a braking resistor .
