Fig. 1 is a schematic structural view of a starter-equipped motor of the present invention.

In the figure: 1. a motor body; 11. a flywheel housing; 2. a starter; 3. a driving gear; 4. a driven gear; 5. a connecting plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

As shown in fig. 1, a starter-equipped motor includes a motor body 1 and a starter 2.

In particular, the starter 2 is a mechanical device that is mature and widely used in the prior art, and the specific structure thereof is not the point of the invention, so the specific structure and the operation principle thereof are not described in the present embodiment.

The starter 2 is fixedly arranged on one side of the motor body 1, an output shaft of the starter is arranged in parallel with the output shaft of the motor body 1 in the same direction, a driving gear 3 is fixedly arranged on the output shaft of the starter 2, a driven gear 4 is fixedly arranged on the output shaft of the motor body 1, and the driving gear 3 and/or the driven gear 4 are/is connected with corresponding shafts through keys or splines. The driving gear 3 and the driven gear 4 are mutually meshed, and the tooth number of the driving gear 3 is smaller than that of the driven gear.

The motor body 1 is connected with a mains supply, the starter 2 is connected with a storage battery, when the motor body 1 is started, the starter 2 is electrified and enables the driving gear 3 to be meshed with the driven gear 4 through a transmission mechanism of the starter 2, so that the generator is driven to rotate, and after the generator reaches a normal rotating speed, the starter 2 is powered off and stops rotating and separates the driving gear 3 from the driven gear 4.
