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

Greenville, DE —  PITTMAN Series GM8000 brush-commutated DC gearmotors from Servo2Go.com feature 11-slot skewed armatures to minimize magnetic cogging (or reluctance torque) and promote quiet and smooth operation.  

Pittman's GM8000 Series DC Servo Gearmotors


Series GM8000 gearmotors are available with a range of 11 standard reduction ratios from 6.3:1 to 187.7:1.  Peak torques up to 175 oz-in can be achieved with wide-face gear options. Armatures are skewed to minimize magnetic cogging, even at low speeds, and windings are resin-impregnated for greater reliability in incremental motion applications.  Two-pole permanent magnet stators are constructed of ceramic magnets enclosed in heavy-gauge steel return rings.  Diamond-turned commutators ensure maximum brush life.

GM8000 series gearmotors are available with and without encoder feedback, and are typically shipped in stock to 3 weeks.

Typical industry applications include data storage, medical/biotech, semiconductor, automation, commercial aviation, and others requiring high performance and reliability.
