Constant Force Cartridge Brush Holder®
US Patent No. 6,731,042 B1
| The Phoenix Constant Force Cartridge Brush Holder® is a "first of a kind" brush holder offering the traditional benefits of a cartridge style brush holder with the added advantages of a constant force spring. You benefit from the easy and convenient assembly, externally replaceable brushes, extremely tight tolerances, uniform brush wear, substantially longer brushes, accurate spring pressure and superior commutation. |
| A significantly longer brush in the same amount of space delivers more than double the brush life resulting in less frequent brush replacement. |
| Even, constant brush wear ensures superior commutation and less arcing. |
| Accurate spring pressure results in better motor performance for more consistent trouble free motor use. |
| The Phoenix Constant Force Cartridge Brush Holder ® provides a consistent high force over the entire life of the brush. With compression springs, you are required to specify a wide range of acceptable spring pressures. Now the Phoenix Constant Force Cartridge Brush Holder ® allows you to pick the optimal spring force with precision and delivers predictable, optimal force for superior motor performance over the extended life of the brush. |
