Tough Jobs: Focus on Customized Motor Design for Medical Equipment OEM

From Groschopp, Inc.
 

 

Long motor life to achieve tough specifications such as 50,000 hours of continuous operation requires a quality product and a detailed understanding of the application. When this OEM faced expensive product recalls and field retrofits with another vendor's motor, he stepped back from his application and with the classic engineer's approach, asked the objective question "what affects the life of the motor?"

A manufacturer of positive displacement pumps and leak testing equipment, this OEM prides themselves in performance, flexible and innovative design, and gear pump engineering excellence. After failures with the other manufacturer's motor that prompted recalls, they came to Groschopp to determine what could be done to extend motor life and achieve higher reliability.

The design team had a simple response to that question-"temperature". Starting with their standard motor design, they identified three areas that could lead to failure in this particular application before 50,000 hours.
