Our Milwaukee headquarters houses a state-of-the-art, climate-controlled, 2500 sq. foot motor test lab. We can replicate field conditions or customer specifications to provide accurate results for load, environment and duty cycle.
Over 150 stock motors to couple with your motor for life testing.
In this lab, we test our products in many capacities to engineer them for the toughest environments. We also offer motor testing to customers to help develop application-specific grades to improve motor performance.
Our dedicated Wind Team provides problem diagnosis, installation guidance, part maintenance recommendations and
industry-leading brush & holder knowledge.
With lightning strikes being a major concern for wind turbines, Helwig Carbon offers brushes and brush holders that meet the rigorous demands of lightning protection. Our brush grades perform well in electrical surges and are not prone to wear. Low resistivity ensures that electrical currents are directed away from crucial components. Our brushes and brush holders are unsurpassed in quality and are a perfect safeguard for your renewable energy investment.
A lightning strike is the result of an electric discharge between the atmosphere and an object. Most cloud to ground strikes are concentrated to a physical location, which is referred to as a “termination”. Interestingly, the bright flash that we call a lightning strike is only about one inch in diameter, even though it seems to be much more significant to the naked eye, video, and photographs.
