relaxed length Extreme extension annmmnmnn www/mwq Long extension capibility for constant load CONSTANT FORCE SPRING FOR CARBON BRUSH Feature: Advantages of Twin Coil Comparing with Single Coil Motor brush springs are constant force springs that are specially constructed to provide the ideal method of ensuring consistent, dependable pressure to electric motor commutators, we can provide you both single coil constant force springs and twin coil constant force springs for carbon brush. Advantages of Constant Force Spring for Carbon Brush: 1. Constant pressure for commutator in any brush length. 2. Increases brush life, reduces electrical wear. 3. Compact design for overall motor size. 4. Allows longer brushes. 5. Allows larger commutators. 6. Reduces spark, lower influence of electromagnetic interference (EMI) There are a number of different spring design possibilities for a given application, we strongly suggest you to consult with a Ming-Tai engineer early in the design phase. 1. To afford maximum brush lengtth and double the load of single coil. 2. To allows a minimun motor size. 3. To offer better load for its symmetry.

HOW TO CHOOSE SUITABLE CONSTANT FORCE SPRING FOR CARBON BRUSH 1. Width of carbon brush (A) : O.D (D) must smaller than Spring width(A) 2. Height of carbon brush (B) : Spring width must smaller than brush height 3. Wearing length of carbon brush (C) : Stoke must bigger than brush wearing length 4. Pressure on commutator : The load of the spring (L) 1. Width of carbon brush (A) 2. Height of carbon brush (B) : Spring width must smaller than brush height 3. Wearing length of carbon brush (C) : Stoke must bigger than brush wearing length 4. Pressure between commutator and carbon brush (L) : The...
