## Abstract

A modular device that can operate as an electrical generator. First and second coil support plates are arranged in parallel orientation relative to each other forming a gap between the first and second coil support plates. Removable C-cores, each having wire coils, are removably attached to the first and second coil support plates. A rotor disc having selectively arranged magnets is disposed in the gap between the first and second coil support plates and is permitted to rotate about an axis that is perpendicular to the rotor disc and the parallel first and second coil support plates; a drive motor can power rotation of the rotor disc. As the disc rotates, electrical current is generated. The C-core assemblies can be interchanged, checked, removed and/or replaced while the electrical generator remains in operation without requiring cessation of such operation.

## Claims

### Claim 1

An apparatus for generating electricity comprising:
a) a first coil support member having an outer surface and an inner surface;
b) a second coil support member having an outer surface and an inner surface, wherein said second coil support member is spaced apart from said first coil support member to define a gap between said first coil support member and said second coil support member;
c) a rotor disc having a center point, wherein said rotor disc is rotatably disposed in said gap between said first coil support member and said second coil support member;
d) a plurality of magnets disposed in said rotor disc;
e) a first plurality of coil assemblies removably mounted to said first coil support member, wherein said first plurality of coil assemblies further comprises a first plurality of wedge-shaped members arranged in a circular pattern, and wherein at least one of said first plurality of wedge-shaped members is configured to be selectively removed and replaced without interrupting generation of electricity;
f) a second plurality of coil assemblies removably mounted to said second coil support member, wherein said second plurality of coil assemblies further comprises a plurality of wedge-shaped members arranged in a circular pattern, and wherein at least one of said second plurality of wedge-shaped members is configured to be selectively removed and replaced without interrupting generation of electricity; and
g) a power source for rotating said rotor disc.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein each of said plurality of coil assemblies further comprises a C-core having a first leg and a second leg.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein said C-core comprises square tubing.

The apparatus of claim 2, wherein said coil assemblies further comprise:
a) a first wire coil disposed on said first leg; and
b) a second wire coil disposed on said second leg.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein said magnets are disposed in at least two concentric circular patterns positioned around said center point of said rotor disc.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the polarities of said magnets alternate around each of said circular patterns.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein a first circular pattern of magnets is aligned with said first wire coil and said second circular pattern of magnets is aligned with said second wire coil.

### Claim 9

A method of producing electricity comprising:
a) providing a generator comprising:
i) a first coil support member having an outer surface and an inner surface;
ii) a second coil support member having an outer surface and an inner surface, wherein said second coil support member is spaced apart from said first coil support member to define a gap between said first coil support member and said second coil support member;
iii) a rotor disc having a center point, wherein said rotor disc is rotatably disposed in said gap between said first coil support member and said second coil support member;
iv) a plurality of magnets disposed in said rotor disc;
v) a first plurality of coil assemblies removably mounted to said first coil support member, wherein said first plurality of coil assemblies further comprises a first plurality of wedge-shaped members arranged in a circular pattern, and wherein at least one of said first plurality of wedge-shaped members is configured to be selectively removed and replaced without interrupting generation of electricity;
vi) a second plurality of coil assemblies removably mounted to said second coil support member, wherein said second plurality of coil assemblies further comprises a plurality of wedge-shaped members arranged in a circular pattern, and wherein at least one of said second plurality of wedge-shaped members is configured to be selectively removed and replaced without interrupting generation of electricity;
b) rotating said rotor disc within said gap about an axis of rotation that is oriented perpendicular to said rotor disc; and
c) generating electrical current in said coil assemblies.
