Abstract

The invention provides a rotor iron core and a motor with the same. The rotor core includes: a rotor punch, on which there are multiple installation grooves for installing magnetic steel, and at least one of the multiple installation grooves is provided with a connecting groove on the wall of the groove. A connecting groove is provided on the groove wall of the mounting groove on the rotor punch, so that when the magnetic steel is installed in the mounting groove, whether it is dipped in paint or glued, the magnetic steel can be firmly installed on the magnetic steel. installed in the slot. Due to the arrangement of the dipping tank, the installation tank of the magnetic steel will not hold air during the installation process, so that the technical solution of the application is used to install the magnetic steel, and the magnetic steel can be installed in place without knocking on the magnetic steel. The stability and reliability of the rotor core are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, and 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, which are rotor punching pieces, magnetic steel installation grooves, installation grooves, and magnetic steel. The magnetic steel installation groove has different cross sections, and the gap between the magnetic steel and the installation groove is between 0.03mm and 0.1mm. After the rotor is assembled, the whole needs to be dipped in paint or fixed with magnetic steel glue during the assembly process. This is due to the high speed of the high-speed motor and the large centrifugal force, so the magnetic steel inside the rotor core needs to be fixed to prevent Magnetic steel flying out by centrifugal force. [0003] Using the method of dipping, after the rotor is dipped in paint, t...
