Claim 0:
1. An electric machine comprising a rotor, a stator, and a fluid-based brake arrangement for said rotor, said fluid-based brake arrangement having a fluid circuit for transporting a brake fluid, said fluid circuit comprising a fluid channel arrangement having at least one radial fluid channel segment extending radially through a part of said rotor so as to allow for directing brake fluid from an inner radial rotor side to an outer radial rotor side, such that, during rotation of said rotor about an axial center axis, acceleration of brake fluid in said at least one radial fluid channel segment causes a reaction force exerting a braking torque on the rotor.
