Abstract

The invention provides a rotor structure and a motor with the same. The rotor structure includes an inner rotor core; an outer rotor core assembly, the outer rotor core assembly is arranged at intervals along the circumference of the inner rotor core; a magnetic isolation bridge assembly, the inner rotor core is connected to the outer rotor core The components are connected, and the magnetic isolation bridge component is made of non-magnetic material. By setting the magnetic isolation bridge assembly in the rotor structure as a non-magnetic material, this setting can avoid magnetic flux leakage between adjacent magnetic poles, effectively improving the efficiency of the motor, and at the same time, the magnetic isolation bridge assembly can play a role in connecting the internal The function of the rotor core and the outer rotor core assembly effectively improves the strength and stability of the rotor structure.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure and a motor having the same. Background technique [0002] The motor is a device in which the circular current in the stator winding after electrification generates an induced magnetic field, and then attracts the magnetic steel in the rotor to drive the rotor to rotate, thereby obtaining power. The existing built-in rotor punching mostly adopts the structure with magnetic isolation bridge and magnetic steel limit. The role of tiles to increase the magnetic induction. However, it is found through electromagnetic simulation that although the magnetic isolation bridge effectively connects the poles of the rotor punch and separates the magnetic tiles, the magnetic flux leakage phenomenon is still relatively serious. Therefore, the existing rotor punch magnetic isolation bridge They are all designed to be as thin as possible in order to reduce magnetic flu...
