Ming Tai offers high quality constant force spring, which can be applied to all types of brush motors, generators and alternators, slip ring and grounding systems. Constant force spring  makes carbon brush reliable, having long life cycle and reduced maintenance.  Furthermore, any length of brush is available to be hold by constant force spring, and to reduce spark, and to lower influence by electromagnetic interference.

Constant force spring designed for carbon brush is suitable for all types of brush motors, generators and alternators, slip ring and grounding systems of a turbine generator, electrical engineering, hydro-electric, and railway grounding systems.

Large constant force springs with clip can push large carbon brushes that applied to huge slip ring of generator, in which the current between the rotor and external circuit is periodically reversed. In wind turbine, constant force spring can be applied to slip ring, grounding system, lightning arrestor brush as well. The picture shows the application of yaw drive motor in wind turbine.
