Ming Tai Industrial Co., a total solution of steel strip spring, has developed a wide range of Constant Force Springs, which can be widely used in rail vehicles and wind power turbine.

In rail vehicle, constant force springs designed for carbon brushes can be applied to alternators; auxiliary motor, blower motor, traction motor, slip ring and earth return current units. In wind power turbine, it can be applied to grounding system, motor commutator as well.

Constant force springs ensure that the carbon brush works consistently by dependably exerting constant pressure to increase brush life and to reduce electrical wear. Carbon brushes can also be used for earth return current units to divert static and induced electric currents in a motor shaft away from the bearings, and to protect them from pitting and damage.

Constant force spring keeps carbon brush to rub against the outside wall of a rotating slip ring. As the metal ring turns, the electrical current or signal is conducted through the brush to the metal ring making the connection.

Ming Tai offers a number of different constant force springs for carbon brush application. It can be classified in two types, the Single Coil Type and the Twin Coil Type. Ming Tai also offers variety mounted clips for different occasion need.

We strongly suggest you contact us for more detail information in the design phase. Even it is just a simple idea; Ming-Tai will develop optimized solution of springs to fulfill your product innovation.
