A stator permanent magnet high-speed motor

The invention provides a high-speed electric machine with a stator and permanent magnets. The high-speed electric machine consists of two stator end magnetic rings, the permanent magnets, a stator back yoke, a stator core, a winding coil, a rotor core, rotor shafts and rotor end magnetic rings, wherein the permanent magnets are arranged in the two stator end magnetic rings, and the rotor end magnetic rings are arranged in the permanent magnets; gaps are reserved between the permanent magnets and the rotor end magnetic rings, so that shaft end air gaps can be formed; the stator back yoke is positioned between the two stator end magnetic rings and is internally provided with the stator core, the winding coil is arranged on the teeth of the stator core, and the stator core is internally provided with the rotor core; gaps are reserved between the stator core and the rotor core, thus forming shaft hollow air gaps; and the rotor shafts are arranged in the rotor core and the rotor end magnetic rings and is used for providing magnetic paths for rotor laminated layers and the rotor end magnetic rings. The high-speed electric machine provided by the invention has the advantages of high rotor mechanical strength, less permanent magnet loss, good permanent magnet heat dissipation condition, convenience in processing and manufacturing, and the like.
