ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a magnet generator, and more particularly to a magnet generator having multiple magnets received in a positioning seat of the stator and a plurality of faces each corresponding to one of the magnets. With such an arrangement, when the generator of the invention is in operation, the generated rotation torque is greatly increased so as to drive a working disk with more power.
2. Prior Art Description
With reference to
FIGS. 10
,
11
, a conventional magnet generator includes a shell
10
, a silicon steel magnet
11
(stator), a rotator
12
and a shaft
13
.
The shell
10
has a base
100
enabled to be mounted on a table (not shown), a compartment
101
defined in the shell
10
and a cover
102
engaged with the shell
10
to encase the rotator
12
and the shaft
13
in the compartment
101
and having a through hole
103
for the extension of the shaft
13
.
The stator
11
securely received in the compartment
101
and distributed around an inner periphery defining the compartment
101
has multiple T-shaped faces
110
extending out from a periphery of the stator
11
and a multiple sets of coils
111
each mounted around one of the faces
110
.
The rotator
12
is received in the compartment
101
and surrounded by the stator
11
. The stator
12
has multiple protrusions
120
each corresponding to one of the faces
110
of the stator
11
. A slit
121
is defined between two adjacent protrusions
120
and has a magnet
122
received therein. The rotator
12
further has an upper cover
123
with an central opening
123
′ and a lower cover
124
also with a central opening (not shown and numbered).
The shaft
13
extends through the central openings
123
′ of the upper cove
123
, the stator
12
and the central opening of the lower cover
124
. A lower distal end of the shaft
13
engages with a bottom face of the base
100
and an upper distal end of the shaft
13
extends through the through hole
103
of the cover
102
. A disk
130
securely formed on the shaft
13
is provided to securely engage with the upper cover
123
of the rotator
12
.
When the conventional generator is assembled and is controlled by the computer to work, the rotator
12
rotates around the shaft
13
. Each of the magnets
122
continuously or intermittently corresponds to one of the faces
110
. The generator generally drives a working disk (not shown) to rotate by the torque generated by the rotation of the rotator
12
.
Although, the torque does drive the working disk to rotate, the thickness of the shell
10
and the thickness of an outer periphery of the stator
11
to the face
110
cause the driving radius (d) not sufficient and effective, which leads that the rotation range of the rotator
12
not enough. The rotation torque generated by the generator is not able to meet the requirement.
To overcome the shortcomings of the above mentioned patents, the present invention provides an improved magnet generator so as to obviate the above mentioned problems.
SUMMARY OF THE INVENTION
The primary objective of the invention is to provide an improved other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
