Definitions
- This invention is about the electrical motor, compare to the traditional motor, this invention has a powerful output.
- Fig 1 shows the A-view of one section about this invention
- the rotor's diameter and the cavities of silicon steel sheets are flexible, depends on the power needed, see fig 3..
- the bearings are very close, so the diameter can be larger.
Abstract
This design of powerful motor has axial permanent magnets,both ends of the magnets are useful. And because the two bearings are very close,so the diameter of the motor could be bigger; the cavities on the silicon steel sheets could be more bigger than traditional motor,so more coils can go through the cavities then bigger current,which makes the motor has a higher power output; and maybe more than one stage if needed.
Description
A DESIGN OF POWERFUL ELECTRIC MOTOR
Technical field
This invention is about the electrical motor, compare to the traditional motor, this invention has a powerful output.
Background
For traditional motor, if you want a powerful output, there are 3 ways:
1 . Prolong the rotor and add more silicon steel sheets, but if the rotor too long, the axis will deformation because of the weight.
2. Enlarge the diameter of motor, after the rotor's diameter is defined, because of the magnet permeability, so the power is defined, no mater how big the cavity or current.
3. Way1 and way2 together, still not very powerful.
Summary of the invention
Fig 1 shows the A-view of one section about this invention
1 .motor coils, shows 1 phase
2. silicon steel sheets
3. permanent magnet
4. rotor
5. bearings
6. shaft
Brief description of the invention
Basic theories are same, but not like traditional motor, the magnetic line is axial, both ends of the permanent magnet are useful.
The rotor's diameter and the cavities of silicon steel sheets are flexible, depends on the power needed, see fig 3..
The bearings are very close, so the diameter can be larger.
If possible more stages connect together to ensure enough power output.
Claims
1 . This design of powerful motor characterized by, the permanent magnetic line is axial.
2. This design of powerful motor characterized by, the silicon steel sheets has a 'C shape.
3. This design of powerful motor characterized by, the rotor's diameter and the cavities are flexible, which depends on the power needed.
4. This design of powerful motor characterized by, could has more than one stage if needed.
