Specifications: * 7.91" diameter / 5.64" length * 7/8" shaft with 3/16" keyway by 1.75" long (threaded center) * Torque constant: 1.14 in-lb/Amp (0.13 Nm/Amp) * 12V to 48V (has been run up to 96V / 45 sec. max. / 25 hp) * 72 RPM per volt (3456rpm @ 48V / continuous duty) * Can be used as a generator, makes power when turned (Requires 100 amp blocking diode) * Great for VERY low voltages at high amp loads (Perfect PMG for making hydrogen) * Perfect for building simple, cheap and dependable low voltage wind turbines. * A put-up and forget design! Expect decades of dependable service life. * Rain, ice and weather proof electronics. * Lithium/Graphite brushes last up to 275,000 hours (When used as electric generator in wind power systems) * 10 horsepower continuous duty at 48 volts. * Max motor currents: 330A for 2 minutes / 480A for 45 seconds. * 10 horsepower max at 48 volts continuous duty! * 14 horsepower max at 60 volts continuous duty with optional air cooling port. * 19 horsepower max at 72 volts for 2 minutes only! * 28 horsepower max at 96 volts for 45 seconds only! * Works for both CW or CCW rotations. * Epoxy/Lam rotor efficiency = 94% (Brushed motors convert more electricity into usable horsepower) * Weighs 12kg. / Dimensions - 8"X 9"X 9" well here is the rest of this story
In this motor the iron laminations are rectangular, which made it possible to have them commercially made from material intended for this purpose without the expense of a special stamping tool. Because the flux passes through the laminations along one axis only, it became possible to take advantage of grain-oriented material normally used in large transformers. This has much better magnetic properties along the grain orientation but worse properties in other directions, so in the traditional type of motor it gives little or no benefit.
This motor went into small-scale production in 1988 with the EV conversion firm London Innovation and later with the Lynch Electric Motor Company (LEMCO). In 1989 four of them powered the boat "An Stradag", driven by the Countess of Arran, to a world record speed for an electric boat of just over 80 km/h (50 mph). The motor was adopted by the Swiss company ASMO for use in its electric go-kart drive systems[3]. Its efficiency extends the life of the batteries and so improves the economics of running an electric kart track. The patents and license rights for the manufacturing of the Lynch motor are held by the Lynch IP company, which has sold a license to Briggs and Stratton to manufacture the ETEK motor. LEMCO continued to manufacture motors and now trades under the name of LMC (Lynch Motor Company) which now owns the Lynch IP company and therefore all rights and patents pertaining to the motor. In 2009, Cedric Lynch has parted company with LMC and is working for Agni Motors, which is producing similar motors. Lynch motors are mentioned as being a unique product in the documentary "The White Diamond" about a lighter than air ship: "This is actually an interesting motor. It is designed by somebody called Lynch in England. He never went to University and doesn't know any mathematics and stuff like that, but he taught himself electrical engineering. And it turns out the motor he made is one the world's leading in terms of power and mass. And he's developed his own kind of algebra to do that but no other academic can understand what he's doing. But he seems to know more than many academics in electrical engineering departments because this motor is very good performance ... Cedric Lynch
