Problems solved by technology

[0004] The traditional drive motor currently on the market has a baffle at the end of the rotor, and the baffle is installed on the rotor bracket through bolts to block the magnetic steel and the punching plate. It is bulky and has the following obvious defects: 1) Waste of space, For the compact drive assembly of the whole vehicle, the baffle increases the space requirements for the engine compartment; 2) Waste of materials, because the rotor has magnetic steel, the baffle must be made of non-magnetic precious metal materials; 3) It is not conducive to the assembly of the rotor, which increases Assembly difficulty and process reduce assembly efficiency; 4) Bolts are easy to fall off and cannot be tightly fixed

Embodiment Construction

[0019] A new type of motor rotor structure, including a ring-shaped punch 20, a positioning key 21 is arranged on its inner circle, a keyway 31 matching with the positioning key 21 is provided on the outer ring of the rotor bracket 30, the punch 20 and the rotor The outer ring of the bracket 30 has an interference fit, and the punch 20 has a plurality of slots 22 for inserting the magnet 10 along its circumference. The magnet 10 and the punch 20 have an interference fit. Injection plastic 40 is filled in the slot 22 gap between punching sheet 20, as figure 1 , 2 , 5 shown.

[0020] Such as figure 1 , 4 As shown, the outer ring of the rotor bracket 30 is an annular retaining wall 32 arranged on the rotor bracket 30, the inner circular surface of the punch 20 is closely attached to the outer circular surface of the annular retaining wall 32, and is arranged on The positioning key 21 on the inner circle of the punching piece 20 matches with the keyway 31 provided on the annul...

Abstract

The invention relates to a novel motor rotor structure comprising a punching sheet with the circular shape, and the inner circumference of the punching sheet is provided with positioning keys. The outer circumference of a rotor frame is provided with positioning key grooves matching with the positioning keys, and the punching sheet and the outer circumference of the rotor frame are in fit clearance; a plurality of inserting grooves allowing a magnetic steel to insert are arranged on the circumference of the punching sheet, the magnetic steel and the punching sheet are in fit clearance, and plastic rubber is injected in the clearance between two ends of the magnetic steel and the punching sheet. Since the punching sheet and the rotor frame are in fit clearance, the punching sheet and the rotor frame can be fixed tightly while the punching sheet is free of being pressed by a baffle; the magnetic steel and the punching sheet are in fit clearance, the plastic rubber is injected in the clearance between the magnetic steel and the punching sheet to fix the magnetic steel, the ends of the magnetic sheets are free of being shielded by the baffle, the magnetic steel can be applied to the motor rotor assembly directly, the occupied space is small, the rotor structure is simple, the space of the motor is saved effectively, material cost is saved, and the assembling efficiency of the rotor is improved.

Description

technical field [0001] The invention relates to the technical field of motor rotors, in particular to a novel motor rotor structure. [0002] Background technique [0003] With the further increase of global car ownership, the energy crisis, environmental pollution and global warming are becoming more and more prominent. New energy vehicles, especially hybrid vehicles, have become the focus of the development of domestic and foreign automobile companies. No matter from the point of view of environmental protection or energy, hybrid electric vehicles need a big development in the future, and its development will be related to the rise and fall of many industries, and may become a new economic growth point in the future. In my country, hybrid vehicles have a unique market, and there are very serious traffic problems and vehicle exhaust pollution problems in metropolises. As a small energy-saving and emission-reducing daily means of transportation, hybrid electric vehicles ar...
