Carbon brush manufacturing

Carbon brush manufacturing
Increasing the energy efficiency and raising the dynamics of the press.
Situation

Approximately 500 million high-quality carbon brushes are manufactured per year. New electrically operated servo spiral presses are used to optimize the process.

Problem

The brake energy is wasted as heat. The dynamic of the machine is pushed to its limits.

Goal

Increasing the energy efficiency and raising the dynamics of the press.

Solution

Use of 2 PXTFX via “Plug & Play”. Stabilizing the DC link by storing brake energy and providing it again once needed.

Advantages

Increasing energy efficiency

The energy efficiency is increased because the brake energy is temporarily stored and made available as required.

Increasing productivity

Productivity is increased by increasing dynamics

Recovering brake energy

The brake energy is fed back into the system.
