Schragen.

/ˈʃrɑːɡə/

Etymology: < the name of H. K. Schrage (fl. 1914), Swedish engineer.

Used attributively and in the possessive to designate a type of three-phase a.c. motor invented by Schrage, in which a commutator motor is combined with an induction motor to provide speed variability at high torque.
