This technical scheme is particularly useful for reducing the vibration and the noise when using, specifically: the one end of the casing that is connected with the connector sets up the tang, and the thickness of tang is very increased, can be accurate, level and smooth processing tang, reduces the degree that the connector is beated during the use, reduces motor vibration, also noise abatement.

As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure: the main body of the plastic package machine shell is cylindrical, and the inner annular surface of the spigot is positioned on the inner cylindrical surface of the main body of the plastic package machine shell. In general, in order to facilitate plastic packaging and demolding, the main body of the plastic package casing (i.e., the portion excluding the motor end cover) is cylindrical, the inner wall surface is cylindrical, and the radially inner end of the spigot extends to the inner wall surface of the main body of the plastic package casing. The radial thickness of the spigot is larger than or equal to or slightly smaller than the maximum radial thickness of the stator coil with the winding, the radial thickness of the spigot in the improved technical scheme is far larger than that of the spigot in the prior art, meanwhile, the plastic material is more convenient to process, the precision is better, the matching of the shell and the connection is better, and the vibration and the noise of the motor are effectively reduced.

The outer ring surface of the spigot is matched with the wall surface of the inner cavity of the connecting piece. I.e. the radial thickness of the spigot is adapted to the radial dimension of the inner ring cavity of the coupling.

The utility model discloses beneficial effect who has: 1. the stator coil with the winding is plastically packaged in the shell, so that the motor structure is more compact. 2. The motor end cover and the shell are of an integrated structure, motor parts are reduced, machining and assembling procedures are reduced, the length of the motor is reduced, cost is reduced, the distance between a fan arranged outside the motor end cover and a winding stator coil is closer, an internal heat dissipation effect is better, temperature rise is lower, and the motor is more reliable to use. 3. The one end of the casing that is connected with the connector sets up the tang, and the thickness of tang is very increased, can be accurate, level and smooth processing tang, reduces the degree that the connector is beated during the use, reduces motor vibration, also noise abatement. 4. The stator coil with the winding is plastically packaged in the shell, so that the waterproof and moisture-proof performance is greatly improved, and the service life of the motor is longer.
