It is an object of the invention to provide a kind of rotor of disc type electric machine, solve that energy consumption is big, volume is necessarily large and bulky, can not
The problem of exporting constant nominal torque.
The present invention is achieved in that a kind of rotor of disc type electric machine, which includes yoke disk and positioned at the magnetic
Set of permanent magnets on yoke disk, the set of permanent magnets rounded distribution on the yoke disk.
The present invention further technical solution be：The yoke disk circle centre position is equipped with shaft hole, and the yoke disk is equipped with
Heat emission hole.
The present invention further technical solution be：The set of permanent magnets is by set of permanent magnets into the permanent magnet is fan-shaped.
The present invention further technical solution be：Interval between the permanent magnet is equal.
The beneficial effects of the invention are as follows：The consumption of conventional motors excitation field is substituted with permanent magnetism, here it is permanent magnet iron coreless
The real Ultra-High Efficiency of disc type electric machine, high energy saving core；It is high using the power of motor density of rotor of the present invention, for volume
With weight require place application and be to select well；Low noise；Controllability is strong；It can be exported in full active section constant
Nominal torque, direct heavy load starting.
Brief description of the drawings
Fig. 1 is a kind of structure chart of the rotor of disc type electric machine provided by the invention；
Reference numeral：1. yoke disk, 2. permanent magnets, 3. heat emission holes, 11. shaft holes.
Embodiment
Fig. 1 shows a kind of rotor of disc type electric machine, which includes yoke disk 1 and on the yoke disk 1
Set of permanent magnets, the set of permanent magnets rounded distribution on the yoke disk 1；1 circle centre position of yoke disk is equipped with shaft hole 11,
The yoke disk 1 is equipped with heat emission hole 3, plays the role of heat dissipation to using the motor of the rotor；The set of permanent magnets is by permanent magnetism

The permanent magnet 2 is sector, has been to select well for the place application that volume and weight requires；The permanent magnet 2
Between interval it is equal.
The present invention substitutes the consumption of conventional motors excitation field with permanent magnetism so that permanent magnet iron coreless disc type electric machine high efficiency,
It is high energy saving；Permanent magnet 2 is designed as fan-shaped and there is interval, and on yoke disk 1, above-mentioned permanent magnet 2 is set 2 planar design of permanent magnet
Meter adds magnetic flux so that power of motor density is high, and constant nominal torque can be exported in full active section, and direct heavy duty is opened
It is dynamic, so that energy-efficient；Yoke disk 1 is equipped with heat emission hole 3, and certain work is played for the heat dissipation problem of high power density motor
With.
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
