Dear sir, Basically we are designing a tractor engine control system. The engine shaft of dia 30 mm is rotating with a speed of 3000 to 6500 rpm.The palce availability is 88 mm circular dia and length of 200 mm(cylindrical shape).In that are we are suppose to fix an DC alternator/generator which should produce 28v Dc with 75/100 Ampsfor the operation of the sensors and controls. We need brushless alternator for sucha system. We a re making a proto type . If this gets clicks we have atie-up with mahindra who is no.1 in tractors manufacturing in india,they are interested to buy our system. dear sir, we need a Brushless generator produces 28v dc 75/100ampwhere our engine shaft rotates with a rpm in between 3000 to 6500 and the shaft dia is 30mm.In between these speeds we need to produce a 28v dc 100amps. please give us a solution and quote your price. size should be 80 mm dia and length is 200 mm. quantity:6 no's krishnamohan M/s Technosonics 49=47-4/3,NGGO colony,akkayyapalem visakhapatnam Hence we need a dc Generator/ALternator which should give 28 v DC 75/100 Amps. thnaking u sir Krishnamohan
