New fan-cooled A28 motors are designed for applications that require longer duty cycles and even higher power outputs. Low profile leads enable more compact installations.
The fan-motors have ventilation holes in the front and rear aluminum plates to allow for flow-through cooling. The holes in the front plate are positioned so they are not blocked when mounting the motor to a flat surface. These motors also feature low-profile motor leads for better fit into smaller spaces.
