2. in the injection-molded insulating framework, the front side and the back side of the stator are provided with a plurality of insulating frameworks, so that the assembly efficiency is low, neglected assembly is easy, and the insulating frameworks are easy to fall off;

3. the traditional micromotor stator core stamping mode is that a stator and a rotor core are stamped in a complete set, but the outer diameter of the stator core of a part of direct current motor is large, the rotor core is used less or not, so that the waste of partial materials of the rotor core is caused, and the cost of the stator core is increased.

The utility model has the following contents:

the utility model aims at prior art's defect, provide a structural design is reasonable, practice thrift cost, the few novel flywheel generator of assembly process is with the whole stator core that moulds plastics of concatenation formula and have the whole generator of moulding plastics stator core of concatenation formula for novel flywheel generator.

The utility model discloses a realize through following technical scheme: the utility model provides a novel flywheel generator is with whole stator core that moulds plastics of concatenation formula, includes stator and the insulating skeleton of cladding outside the stator, the stator includes a plurality of stator pieces, the stator piece makes up into whole annular stator through joint structure end to end, and the stator piece includes the arc piece and evenly fixes a plurality of tooth posts on the arc piece outer wall, two tooth post formation are used for holding the tooth's socket of coil, insulating skeleton passes through injection moulding on the outer wall of tooth post and arc piece.

In order to firmly fix two adjacent stator blocks, the clamping structure comprises a dovetail groove and a dovetail pin corresponding to the dovetail groove, the dovetail pin is fixed at one end of the arc-shaped block, the dovetail groove is formed in the other end of the arc-shaped block, and the arc-shaped blocks are connected end to end in an inserting mode through the dovetail groove and the dovetail pin to form an annular stator.

In order to facilitate winding of the winding, limiting piece groups are symmetrically fixed at two axial ends of the insulating framework and comprise first limiting pieces and second limiting pieces, the first limiting pieces are located at the tops of the tooth columns, and the second limiting pieces are located at the roots of the tooth columns.

The utility model also provides an install foretell novel flywheel generator is with the whole generator of moulding plastics stator core of concatenation formula.

The utility model has the advantages that: through the surface at the stator setting injection moulding's insulating skeleton, a plurality of insulating skeletons are placed to the tow sides of stator that compare, are difficult for droing, and the steady quality improves production efficiency, reduces the error rate, through the stator piece that sets up the pin-connected panel, can improve the material rate of utilization of punching press silicon steel sheet, practices thrift the cost.
