Cost Effective IP rating of brushless DC motors.

Often the cost of IP rated brushless DC motors is not justifiable in an application.

A full IP rated brushless DC motor is often required for open operation in a food or pharmaceutical manufacturing facility. When all of the factory automation equipment is mounted in an open environment with the manufactured product, a full washdown capability, sealed or even motors with full food grade lubricants is required. However, there is a current trend to over specify a motors IP rating requirement when designing an automation device for use in these environments. For example, a brushless motor might only be a single part of a complex device being used in the environment. It could be a Gripper, automated guide, check weighing device or even a complete robotic arm. All these devices usually contain their drive motors in a casing that is itself a sealed housing. The only exposed part of the motor outside of its protective mounting flange is the shaft and the bearing. This is where this new style of brushless motor excels. A brushless DC outrunner style motor taking full advantage of a conventionally cooled winding that gives unprecedented power per volume characteristics combined with a completely sealed flange, rubber sealed bearing and stainless steel shaft. This style of brushless motor construction can provide an effectively sealed unit at a fraction of the cost of a full IP rated motor and also provide a much higher power to volume ratio.

Pictured here is a version of this style of brushless DC motor in 90mm diameter achieving up to 0.5 Nm with a custom configured winding to suit the speed requirements of direct drive joint actuations.
