Rotor of motor

Abstract

The invention discloses a rotor of a motor. The rotor comprises circular end faces on the two sides and a circular shaft in the middle, wherein the surface of the circular shaft is the rotor surface of the motor; a plurality of grooves are formed on the surface of the circular shaft along the direction of the shaft, and the shapes of the grooves are matched with those of magnets to be fixed; and Ep-138 glue for fixing the magnets is coated on the surfaces of the grooves, and the magnets are correspondingly adhered in the grooves, so that a good fixing effect can be achieved under the working condition that the magnets operate at a high speed for a long term, and the magnets are difficult to slip. The rotor of the motor has a skillful structural design; and by forming the grooves on the rotor surface of the motor to fix the magnets, the magnets are firm and reliable, and the phenomenon that the magnets covering an iron core can be moved because of 70 or more percent of high temperature generated by the motor during long-term operation is avoided. A common iron core has a circular surface integrally, and the rotor of the motor has the grooves for separate fixation, so that the magnets are difficult to move.

Description

technical field [0001] The invention relates to motor components, in particular to a motor rotor. Background technique [0002] Most of the servo permanent magnet motors commonly used in the prior art adopt an integral rotor structure. The current motor rotors are all round, and then the magnetic sheets are glued to the rotor with resin dipping glue. The motor generates kinetic energy through the magnetic field of the magnetic sheets. , and further converted into the required mechanical energy. [0003] The defect of the motor rotor is a round surface is that it only sticks the magnetic sheet to the round surface of the rotor through resin dipping, and the fixation is not firm. When the motor is running, it will generate a temperature of about 70 degrees, which will soften the dipping glue. May dislodge the magnet covering the surface of the shaft as a whole. [0004] When the rotor is running at high speed, the magnetic sheet is easy to be thrown off or fall off under the...
