Motor rotor core convenient to package by plastics

Abstract

The invention discloses a motor rotor core convenient to package by plastics. The motor rotor core comprises a core body. A rotary shaft hole is formed in the core body, a plastic package layer slidably sleeves the outer side of the core body, a plurality of first T-shaped grooves are formed in the outer side of the core body, an opening is formed in a side of each first T-shaped groove, a plurality of second T-shaped grooves are formed in the inner side of the plastic package layer, the first T-shaped grooves are in one-to-one correspondence to the second T-shaped grooves, H-shaped reinforcing rods are clamped in the second T-shaped grooves and are slidably connected with the corresponding first T-shaped grooves, clamp column holes are formed in the H-shaped reinforcing rods, two symmetrical clamp columns are slidably mounted in each clamp column hole, and two clamp grooves are formed in the side walls of each first T-shaped groove. The motor rotor core has the advantages that the motor rotor core is high in practical performance, simple in structure and convenient to operate, the clamp columns are convenient to move, the H-shaped reinforcing rods can be fixedly positioned, and the plastic package layer can be stably mounted on the core body.

[0002] The plastic-encapsulated motor adopts plastic packaging technology to encapsulate the stator core and winding of the motor as a whole with engineering plastics, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. Machines, air conditioners, washing machines and other household appliances and instrument fans, the patent document CN206180721U provides a plastic-encapsulated EPS brushless motor rotor, the additional groove of this structure blocks the EPS brushless motor rotor magnetic steel leakage The magnetic path improves the main magnetic flux of the motor and the operating efficiency of the motor. The special-shaped additional groove ensures the adhesion of the plastic sealing material and makes the motor rotor have high mechanical strength. However, this structure is not convenient for the plastic sealing material. fixed, and the position of the plastic sealing material cannot be reinforced, so we propose a motor rotor core that is easy to plastic seal to solve the above problems
