WOUND-ROTOR MOTORS (SLIP RING ROTOR MOTORS)
Key Features & Benefits
ASYNCHRONOUS MOTOR BRUSHES
Mersen’s metal-graphite and electrographite brushes are suited for wound-rotor motors (slip ring rotor), which are increasingly used, especially in process industry.
Mersen offers a wide range of brush grades, of electrographite and metal graphite type, such as CG677, to cover all operating conditions of asynchronous motors with wound rotor.
Electrographitic grades are prepared from carbon powders and a specific binder; they are then subject to high temperature thermal treatments (>2500 °C) to transform the basic amorphous carbon into artificial graphite, and enhance the physical properties of the grades.
