1. A locking system for an electric propulsor, the system comprising:
a magnetic lock comprising: a first magnetic component disposed on an inner surface of a cavity configured to house a motor of an electric aircraft, the motor including a rotor, wherein the inner surface is adjacent to a surface of the rotor; and
a second magnetic components fixedly attached to the surface of the rotor, and disposed about a central axis of the rotor; and
a controller communicatively connected to the magnetic lock and configured to engage the magnetic lock, in response to a control signal, to prevent a movement of the electric propulsor while the electric aircraft is in flight, wherein magnetic directions of the first magnetic component and the second magnetic component are orthogonal to a thrust direction of the electric propulsor.
