constant-forcecarbonmotor

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. Please work through the product specifications list below, submit your information to Ming Tai. We will create an optimized motor carbon brush spring to meet your demand. Single Coil Type 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) - Twin Coil Type
