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
