magslip
/ˈmaɡslɪp/Engineering
noun
A kind of electric motor designed so that, when it is operating as a receiver, the angular position of its rotor is maintained the same as that of the rotor of a similar motor electrically connected to it and operating as a transmitter. Originally: a particular design of receiver in which the rotor is a simple magnetic member without windings polarized by a fixed coil and moved by a three-phase stator.
Origin
1940s; earliest use found in Electronic Engineering. Probably from mag- + slip.
