Groschopp Fractional HP Gearmotor & Motor Whitepaper

Groschopp Fractional HP Gearmotor & Motor Whitepaper

For electrical and mechanical design engineers in the process of developing applications, choosing a gearmotor can be a tricky and arduous process. Can motors and gearboxes be purchased separately and then matched for an application? Is it better to specify a pre-engineered gearmotor? What are the differences?

Focusing on how to choose the right motor/gearbox combination for your OEM application; Engineering Manager, Seth Hulst and Design Engineer, Loren Kamstra explain cost optimization, performance and other critical application considerations. Outlining the basic motor and gearmotor types and the advantages of each choice will help a designer more easily calculate and choose the best gearmotor for the required application. Even if a new gearmotor is not needed immediately, many of the ideas presented will help audit a current gearmotor’s performance within an application.

Learn how to:

  • Interpret ratings and characteristics of various gearbox types as a “total picture”
  • Select the right motor based on gearbox ratings
  • Identify key application and performance characteristics (beyond speed, torque and life) such as yield strength, operating speed, mounting position, and loading
  • Avoid common mistakes such as selecting a motor that is too large, problems with overheating, and miscalculating yield torque
  • Why thermal and mechanical factors limit gearbox efficiency and performance
  • Understand the effect of torque density on the heat and life of a motor
  • Tips for selecting the correct gearbox ratio
