Abstract
A high-speed permanent-magnet motor rotor relates to the field of motors, and is used for solving problems that a high-speed permanent-magnet motor adopting a solid rotor leads magnetic steel to be separated from the rotor surface or fly off during a high-speed rotating process in the prior art. An inverted T-shaped fixing part is fixedly assembled at the center of an arc-shaped bottom edge of a wedge-shaped fixture block, the wedge-shaped fixture block is mounted at a gap between two adjacent trapezoid permanent magnets, a conical degree formed by two inclined surfaces of the wedge-shaped fixture block is identical to that of the gap between the two trapezoid permanent magnets, the bottom surface of the wedge-shaped fixture block is completely fit with an outer circumferential surface of a cylindrical rotor core at an opposite position, and an inverted T-shaped trough on the cylindrical rotor core is in splicing fit with the inverted T-shaped fixing part. The fixing clamp part is extremely high in fixing strength of permanent magnets, thereby preventing the permanent magnets from being separated from rotor surfaces or fly off when a motor is in high-speed rotation, and having extremely high reliability and safety.
