High power rotary device
A high power rotary device includes a stator comprising a plurality of wire coils each surrounding a non-magnetizable core; a rotor with permanent magnets embedded therein, the rotor being disposed adjacent to the stator, the rotor being mounted on a rotatable drive shaft; a position sensor operably connected to the rotor; and a control circuit operably connected to the position sensor and the wire coils to activate the wire coils. In this motor the control circuit transfers electrical charge from a first coil to a second coil.
1. A stator comprising:
a plurality of wire coils, wherein the wire coils are wound around a non-magnetizable core and attached to a corresponding mounting bracket; and
a plurality of stator frame components;
wherein each mounting bracket is coupled to a stator frame component to form a stator frame assembly having a series of wire coils mounted in a circle such that the wire coils are in a plane parallel to a plane of rotation of a rotor; and
wherein each wire coil can be removed from the stator independently of other wire coils.
2. The stator of claim 1 , wherein the series of wire coils is a first series of wire coils spaced apart along the stator frame components from a second series of wire coils so as to leave room therebetween for the rotor.
3. The stator of claim 1 , wherein the wire coils are molded with a resin.
4. The stator of claim 1 , wherein the stator frame components are aluminum longitudinal strips.
5. The stator of claim 1 , wherein the stator frame components comprise a series of notches formed therein for locating the wire coils at predetermined positions and in a predetermined orientation.
6. The stator of claim 1 , wherein ends of the stator frame components are attached to end plates.
7. The stator of claim 1 , wherein wire leads from each of the wire coils are led through the corresponding mounting bracket.
8. The stator of claim 1 , wherein the stator frame components are longitudinal strips having a wire channel formed therein; and wherein wire leads from each of the wire coils are fed through a corresponding slot formed on a long edge of the longitudinal strips.
9. A method of manufacturing a stator, the method comprising:
providing a plurality of wire coils, wherein the wire coils are wound around a non-magnetizable core and attached to a corresponding mounting bracket;
providing a plurality of stator frame components; and
coupling each mounting bracket to a stator frame component to form a stator frame assembly having a series of wire coils mounted in a circle such that the wire coils are in a plane that is parallel to a plane of rotation of a rotor and such that each wire coil can be removed from the stator independently of other wire coils.
10. The method of claim 9 , wherein the plurality of wire coils is a first plurality of wire coils, the method further comprising:
providing a second plurality of wire coils wound around corresponding non-magnetizable cores and attached to corresponding mounting brackets; and
coupling the mounting brackets corresponding to the second plurality of wire coils to the stator frame components at positions spaced apart from the first plurality of wire coils and along the stator frame components so as to leave room between the first plurality of coils and the second plurality of coils for the rotor.
11. The method claim 9 , wherein providing the plurality of wire coils comprises forming a plurality of wire coils molded with a resin.
12. The method of claim 9 , wherein providing the plurality of stator frame components comprises providing aluminum longitudinal strips.
13. The method of claim 9 , wherein providing the stator frame components comprises forming a series of notches in the stator frame components for locating the wire coils at predetermined positions and in a predetermined orientation.
14. The method of claim 9 , further comprising attaching ends of the stator frame components to end plates.
15. The method of claim 9 , further comprising feeding wire leads from each of the wire coils through the corresponding mounting bracket.
16. The method of claim 9 , further comprising forming a wire channel in the stator frame components; forming slots along a long edge of the longitudinal strips, each slot corresponding to one of the plurality of wire coils; and feeding wire leads from each of the wire coils through the corresponding slot into the wire channel.
