FR Drake engineers have always been proactive about meeting their customers’ needs, including the need for sanitary machines that can tolerate rigorous and frequent machine washdowns. Since standard servo motors cannot withstand high-pressure, caustic washdown processes, FR Drake engineers historically addressed the situation by building stainless steel covers in an effort to protect the motors.
Unfortunately, food particles often caught and collected on seams and rivets surrounding the housing. Also, washdown fluids eventually worked their way into the housing and made contact with the motor. Finally, the caustic chemicals damaged the point where cables connected to the motors, and potentially corroded the housing itself.
