Magnetic-electric automatic gearbox
A magnetic-electric automatic transmission (MEGA) is an electric transmission developed by Volkswagen and presented to the public in 2006 that has not yet been used in a series vehicle (as of 2020).
description
It differs from serial solutions for electrical power transmission ( diesel-electric drive and electric shaft ) in that the motor and generator form a unit and together use the copper windings of only one stator .
A MEGA integrates the electronic power control, drive rotor, output rotor and a sliding common stator in one housing. The design for high torque or high speed can be varied by changing the effective number of turns during operation by moving the stator. This achieves an efficiency of around 80 to 90 percent across all relevant gear ratios. Mechanical couplings are not required. According to the developer, fuel savings of around 10 percent are achieved compared to a manual transmission. The development to series production is still pending.
The combination to a hybrid drive was not a development goal , but would have been easy to achieve and was called a direct hybrid .
