Electronic controllers are designed for battery-powered, electric drive, commutator-based motors and electronically commutated brushless motors with permanent magnets as well as induction motors. They are designed for various drive systems and are built with MOSFET technology. How they operate is adapted to the purpose of the type of motor. As controllers are designed according to the processors, a wide range of functions is possible. They are built for nominal voltages ranging from 12 V to 80 V and control up to 800 A of current.
