Smoke Curtain

July 5, 2011

When it comes to safety, having a motor that is reliable is a must. After testing motors from several different manufacturers, an automated smoke curtain OEM trusted Groschopp to do the job. A top concern for this OEM was the reliability of the motor after prolonged periods of inactivity.

Because the motor would rarely be operating, cost was also a big concern. Groschopp engineers worked extensively with a cast composite material manufacturer to build a strong and inexpensive reducer housing. This, combined with a non-replaceable brush card, provided a cost-effective DC motor solution.

Challenges

  • Adaptable in a range of curtain configurations
  • Highly reliable, especially after prolonged periods of inactivity
  • Low cost
  • Small package to fit in tight space
  • Right angle configuration to work with product design

Solution

  • Composite reducer housing for strength at low cost
  • Right Angle PMDC gear motor with reduced length (compact design)
  • Brush card design (non-replaceable brushes)
  • Intermittent duty allowed a smaller motor to be used

How to use the Motor Search Tool

Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

Select a dominant variable: choose one of the three parameters to narrow your search. The selected variable determines which slider bar you will be able to manually move.

Use the slider corresponding to your dominant variable to further narrow your motor selection. The other sliders will automatically move to show available ranges based on the range of your selected variable.

Results will upload as your search criteria changes. If you have any questions regarding your results or how to use the search tool, you can chat with us using the green tab on the left-hand side of your screen.

Note: Groschopp Universal motors are custom built to fit your application so no additional options are available to narrow the search. Selecting the Universal motor type will prompt a message taking you to the Universal product page.
