Direct current motor with permanent magnet energy injection

This paper presents an original dc motor concept and prototype based on a permanent magnets injection. It was built as an experimental model and certified by a patent of invention in Romania. This motor can be controlled by an adjustable dc supplying voltage as electric input source and by another adjustable magnetic device based on permanent magnets. The main original aspect is the same as a part of the permanent magnets (PM) are situated inside of the dc motor rotor (as armature) and the other part of them is outside of the motor. The outside permanent magnets are connected and grouped, constituting a magnetic device as adjustable magnetic energy source. Both the PM parts (armature and magnetic device) are related between them. As first application field has been identified the automotive propulsion.
