CEDRIC LYNCH and his DISC ARMATURE MOTORS
Many years ago while attending a Battery Vehicle Society (BVS) event, our project manager, Nelson Kruschandl, met Cedric Lynch and Geoff Harding (famous for his electrically propelled human torpedo operations during the 2nd World War) and got a chance to talk batteries and see the electric cycle on which Cedric travelled from London to Birmingham on one battery, without stopping to re-charge.
Some years later in 1996 Nelson again met up with Cedric when a company called Refuelable Electric Vehicles was formed to develop Nelson's patent battery exchange system for road going cars, and they needed to consult an expert about motors.

Cedric built his first motor to enter a competition to see who could go furthest on one battery charge in a boat. The story goes he cut up old baked bean cans to fabricate the interleaves of his armature. The motor produced was mated to an outboard motor shaft and his boat covered many more laps than any other boat that day. Soon after this Richard Fletcher as London Innovation invested in Cedric's designs and later Powergen also invested in Cedric's idea, helping to finance the production of his motor.
The Lynch motor is an unconventional design with a disc armature. It marries the advantages of a conventional, wound armature motor with the benefits of a flat (printed circuit) motor. It is similar to a pancake motor, but is more powerful than any of these technologies. The disc armature has magnets on both sides, doubling the available flux density and shortening the magnetic path. It therefore packs more power per pound and per cubic inch than any other motor technology. Of course such a revolutionary motor is not for every application - it is not as cheap as wound field motors, but for many applications it is a far superior motor. It has a previously unheard of power to weight ratio and also power to volume ratio. It is also highly efficient because of the double magnet design and associated short magnetic path. It also includes integral fan cooling.
The Lynch motor is an important development which spurred other motor designers to improve their products to remain competitive, such as synchronus permanent magnet machines. As a result of the competition between manufacturers the cost of high performance motors and controllers has fallen dramatically. We hope the cost of solar cells also reduces to allow renewable transportation to develop as a viable alternative to carbon fuels.
ELECTRIC BIKE LEGEND
built his electric bike around a mid-drive configuration, also building one of the worlds most efficient light weight
electric motors to power his rig reliably at 60-MPH for significant distances. He would later set several world records with his axial flux motor and bring it to market as the Lynch / Agni motor. Briggs and Stratton would eventually buy this technology which would lead to the Etek motor, which is now famous for making high speed efficient electric hot rods.
zero-emission motorcycle, which has a top speed of 120mph, was shown in action winning the world’s first zero carbon race – the TTxGP in the Isle of
ETEK - US VERSION LYNCH MOTOR
The Etek motor is a brushed 25-pound pancake shaped motor that puts out enormous power for its weight. Depending on amperage and voltage the Etek can easily provide between 15-horsepower and 30-horsepower reliably and consistently (11-kW / 22-kW). A perfect platform for a powerful electric bike if you do not mind the weight. Although brushless motors are considered more modern, a brushed motor like the Etek allows the builder to use very affordable controllers.
Liveforphysics used a newer version of the Etek (the Agni motor), to achieve speeds of over 70mph, and dominate a recent hill-climb event.
Although originally designed by Cedric Lynch, virtually identical motors are now manufactured by separate companies. A variant design is also being manufactured in Germany:-
