avr - linear copper strip wounded regulators in differential winding, plus minus type with negligible losses due to differential winding as regulator part is out of ckt on minimum amd maximum conditions. this regulator is wounded with copper strip where as in market the series type regulator are made of copper wire with highest losses due to series winding. the losses of our regulator are 118th in comparison to others. self lubricating carbon roller assemblies. carbon roller: we are giving self lubricating carbon roller assemblies with working life of 1 lakh track meters instead of carbon brush used by others. our rollers are point contact with least wear and tear as surface area in contact keeps on changing during the motion and heat is dissipated through out the body resulting in very high working life on maximum temperature rise with spring tension be red phase to keep the roller intact with coil for trouble free operation for ages.
