One of our customer was using a geared motor for shaker application. Shakers are used in very silent environment. It needs a low speed of 20 to 200 rpm. Gear box used to achieve low speed of 200 rpm. However cost of achieving low noise level in a gear box is very high. Moreover shakers are used 24 hours a day and 365 days a year. There will be heavy wear on the gears. Considering all these requirements, we designed a very special motor of a very low speed of 500 rpm. Customer was suggested to use timer belt and pulley to reduce the speed to 200 rpm by using a ratio of 2.5:1. |
