Motor Design Reduces Heat

N Series motors run at operating speeds up to 100,000rpm to provide more power with less heat in a smaller package than comparable motors, says the vendor. The operating temperature of a 0.9-inch (22mm) 50,000rpm running motor has been reduced by 25ºC, for example, over previous models. Features include maximum efficiency of up to 80%, and an internal design that minimizes torque ripple for extremely smooth operation throughout the motor’s operating range.
