AMETEK's next generation, Eternity Brush motors are an example of how we contribute toward new motor technology. This family of motors was designed to provide on average twice the life of traditional straight brush counterparts. The value to the user can be seen in less downtime, less maintenance and a better overall cost and value.
Longer brushes mean more life. Traditional brush length is limited by the effectiveness of the spring. AMETEK gets around this obstacle by creating curved brushes. The curved brush allows us to increase the brush length by as much as 2/3. The result is 2-3 times more life over traditional straight brushes. In some lower amp motor applications, like 8 amps or fewer, motors can run as long as 5,000-8,000 hours.
Applications that can take advantage of this technology range from:
- car washes
- Pneumatic Tubes
- Air Plenum/Air Sampling
- Pet Grooming
- Hand Dryers
- Hood or Welding Exhausts
If the application requires 5,000-10,000 hours of use, then a brushless motor makes sense (click here for brushless motors). The price differential between the two can be as much as $150-175. The allows the Eternity brush motor to be very cost effective.
