Motor brush spring and wind turbine maintenance

Research shows that to get the greatest return from turbines, whether onshore or offshore, the bigger the turbine, the better. Wind turbines have proven to produce reliable and pollution-free energy, and as technology innovates, the cost of developing and manufacturing them will only become more affordable.

 Motor Brush Materials and Wind Turbine Maintenance

    Motor brushes are consumables, which means there is significant wear and tear over time and will need to be replaced. While proper wind turbine operation and maintenance requires moderate wear, excessive wear can create carbon dust in the slip ring cabinet, reducing internal isolation.

     Also, a useful tip to keep in mind is that motor brushes that are evenly worn indicate good performance.

Since reliability is critical in wind applications that generate electricity for industrial tasks and homes, businesses and schools, it is important to work closely with your engineers and parts manufacturers to determine the best motor brush materials. Two common options include: Copper carbon brushes are very common and affordable. They can be used for up to two years, but due to the high amount of carbon dust, they need a lot of maintenance. On the other hand, silver motor brushes are more expensive, but cleaner, can withstand harsh weather, and can be used for up to five years.

Slip ring compatibility and design is another component to consider. Although there is wear, your motor brush must maintain a stable surface finish to avoid overtime affecting the performance of the brush. Due to the high cost of repair or replacement of wind turbine electromechanical brushes and slip rings, it is important to consider how the size, location, use (affecting operating temperature) and potential performance of the wind turbine will affect the quality and maintenance level of the components you choose.

Our Qianye precision constant force motor brush spring provides constant pressure for the brush, makes the motor run longer, and enables your design to obtain accurate pressure in the whole life cycle of the motor. Using Qianye’s motor brush spring, you will prolong the running time of the motor or generator.
