A kind of disc type electric machine
Technical field
The present invention relates to motor field, more particularly to a kind of disc type electric machine.
Background technology
The disc type electric machine of high power density can not radiate at present;And also have crust outside outer rotor, not only bad for
Heat dissipation, and energy is not fully used.
The content of the invention
It is an object of the invention to provide a kind of disc type electric machine, solve motor radiating and what energy made full use of asks
Topic.
The present invention is achieved in that a kind of disc type electric machine, which includes rotor, stator and shaft, described
Rotor is divided into the first rotor and the second rotor, the stator between the first rotor and the second rotor, the shaft with
The stator is fixedly connected, and the shaft is connected with the rotor by bearing.
The present invention further technical solution be:The rotor is equipped with radiating groove.
The present invention further technical solution be:The diameter of the stator is smaller than the diameter of the rotor, described first turn
Sub to be connected between the second rotor outer circle week by heat dissipating ring, the heat dissipating ring is equipped with heat emission hole.
The present invention further technical solution be:The shaft upper end is equipped with connecting seat, and the shaft lower end is equipped with platen.
The present invention further technical solution be:The first magnet is equipped between the first rotor and the stator, it is described
The second magnet is equipped between second rotor and the stator.
The beneficial effects of the invention are as follows:Rotor axial Magnetic Field Design of the present invention so that the power density higher of motor, weight
Lighter, flat structure is more convenient for the installation of propeller, and by circumference heat dissipating ring, solve that high power density motor can not radiate asks
Topic, outer rotor designs add the torque arm length of propeller installation so that motor produces the pulling force of bigger.

Embodiment
Fig. 1-Fig. 2 shows a kind of disc type electric machine, which includes rotor 1, stator 2 and shaft 3, the rotor
1 point is 11 and second rotor 12 of the first rotor, and the stator 2 is described between 11 and second rotor 12 of the first rotor
Shaft 3 is fixedly connected with the stator 2, and the shaft 3 is connected with the rotor 1 by bearing 4;The rotor 1, which is equipped with, to be dissipated
Heat channel 5;The diameter of the stator 2 is smaller than the diameter of the rotor 1, the first rotor 11 and 12 excircle of the second rotor
Between connected by heat dissipating ring 7, the heat dissipating ring 7 is equipped with heat emission hole 71;3 upper end of shaft is equipped with connecting seat 8, described turn
3 lower end of axis is equipped with platen 6;Be equipped with the first magnet 13 between the first rotor 11 and the stator 2, second rotor 12 with
The second magnet 14 is equipped between the stator 2.
Shell is not added in the outside of the rotor 1 of the present invention, adds the torque arm length of propeller installation so that motor produces
The pulling force of raw bigger.
The design of the radiating groove 5 on heat emission hole 71, rotor 1 on heat dissipating ring 7, solving high power density motor can not dissipate
The problem of hot.
Fig. 3 shows a kind of heat dissipating ring of disc type electric machine, and heat dissipating ring 7 is located at the first rotor 11 and second rotor 12
Between excircle, the heat dissipating ring 7 is equipped with heat emission hole 71, and the design of the radiating groove 5 on rotor 1, solves high power density
The problem of motor can not radiate.
Fig. 4 shows a kind of external structure of disk type electric motor rotor, and the rotor 1 is equipped with radiating groove 5, solves high power
Shell is not added in the problem of density electrical machine can not radiate, the outside of rotor 1, adds the torque arm length of propeller installation, makes
Obtain the pulling force that motor produces bigger.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
