A brand new microcar
It is driven by an electric motor, the smallest in the market with an external diameter of 1.9 mm and longitude of 5 mm, a stator coil wound with 30 µm diameter wire and a rotor with permanent magnets. This micromotor is run off a 12 V d.c. supply and has speed variation of between 0 and 100,000 rpm. The transmission of movement, conceived, manufactured and assembled by TEKNIKER Micro Machining (TMM), is done by a three-stage reduction which reduces spin speed and increases the outlet pair. The 1st and 3rd stages are identical and consist of a 42 µm-module drive pinion-crown pair with 12 and 60 teeth respectively. The 2nd transmission stage consists of a planet gear speed reducer made up of an 18-toothed (inlet), an fixed external ring with 64 teeth, and three planet gears (outlet) with 23 teeth, all 12 µm module. The final result is a vehicle weighing 1.25 grams and with 20 x 10 mm dimensions the new microcar.Photograph and video availuable in:,http://www.fundaciontekniker.com
