Abstract
A locking assembly for a propeller rotor includes an electric machine having a first mode to energize the electric machine to produce torque and a second mode to deenergize the electric machine to stop production of the torque. A magnetic assembly includes a first component coupled to a first wall via a pivot point, and a second component attached to a second wall. The first component and the second component align proximal to each other when the first component is in a locked position such that the first and second components create a magnetic attraction therebetween to lock the first wall in a stationary position when the electric machine is in the second mode. The first component moves away from the second component to an unlocked position due to rotation of the first wall when the electric machine is in the first mode.
