UL Listed and UL Recognized markings are not the same. UL Listed indicates that the product meets industry and safety standards and has passed UL’s full battery of tests for the product’s intended use. Products that are certified to safety-related standards were evaluated against reasonably foreseeable safety-related hazards including fire, electrical shock, and mechanical issues. Typically, a...

Brushless DC motors achieve the best performance when paired with a drive that matches the motor characteristics. A poorly optimized drive paired with a BLDC motor will adversely affect motor performance and potentially shorten motor life. This article covers several issues related to a non-optimized drive. The initial selection process of a proper drive for...
