Abstract

The invention provides a rotor iron core and a motor equipped with the same. The rotor iron core comprises a rotor punching sheet, wherein multiple mounting grooves used for mounting magnetic steel are formed in the rotor punching sheet; and a connecting groove is formed in the groove wall of at least one of the multiple mounting grooves. By forming the connecting groove in the groove wall of themounting groove in the rotor punching sheet, the magnetic steel can be firmly mounted in the corresponding mounting groove no matter a paint immersion mode or an adhesive pouring mode is adopted; by virtue of setting of a paint immersion groove, the mounting groove does not suffer from suffocation in the magnetic steel mounting process; and therefore, by virtue of the technical scheme disclosed inthe invention, proper mounting of the magnetic steel can be realized without knocking the magnetic steel, so that stability and reliability of the rotor iron core are improved effectively.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular, to a rotor iron core and a motor having the same. Background technique [0002] In the prior art, the existing high-speed motor rotor core structure is composed of four parts, rotor stamping, magnetic steel mounting groove, mounting groove, and magnetic steel. The cross sections of the magnetic steel installation slots have different cross sections, and the gap between the magnetic steel and the installation slots is between 0.03 mm and 0.1 mm. After the rotor assembly is completed, it is necessary to impregnate the whole rotor with paint or fix the magnet steel by filling magnet steel glue during the assembly process. This is because the high-speed motor rotates at a high speed and is subjected to a large centrifugal force, so the magnet steel inside the rotor core needs to be fixed to prevent The case where the magnetic steel flies out due to centrifugal force.
