In the aspect of machining, the more accurate and better the coaxiality of the spigots at the two ends of the base is required, but due to structural limitation, the spigots at the two ends can be machined only by clamping twice during machining, the coaxiality of the spigots at the two ends is difficult to guarantee, in addition, the clamping positions are changed during the clamping twice, deformation in different degrees occurs, the site time that the form and position tolerance of the base is too poor occurs, and the subsequent work and the motor performance are directly influenced. Because the whole size is larger, large-scale equipment or special equipment is needed for processing, and the equipment investment cost is larger. 3. In the process of assembling the motor, a winding core is put into the base, the base needs to be heated firstly, and the base can be placed into the base for heating only by a large enough oven due to the large size of the base, so that the input cost of equipment is high, and the assembly efficiency is influenced.

The second machine base is a part needing to be provided with the stator core, and the stator core and the machine base are generally in transition fit or in small interference fit, so the second machine base needs to be assembled after being preheated. In fig. 2, the upper surfaces of the three bases are flush, and the lower surface of the second base is higher, mainly because the lower surfaces of the first base 1 and the third base 3 are used as a base plane for mounting the whole machine. The second housing 2 is slightly higher because the surface can not be used when the whole machine is actually installed.

Furthermore, the first base 1 and the third base 3 have the same specification and are symmetrically arranged at two ends of the second base 2. The first machine base 1 and the third machine base 3 are standard parts with the same specification, standardized production can be carried out, assembly errors are reduced, and machining precision and machining efficiency are improved.

Based on the technical scheme, because the first machine base 1, the second machine base 2 and the third machine base 3 are standard parts, the axle center coincidence of the three circular installation cavities 4 can be ensured through the accurate assembly of the spigot 5 without adjustment.

Further, the spigot 5 is arranged along an annular shape, and the connecting bolts 7 are uniformly arranged along the annular shape for a circle.

Further, first frame 1, second frame 2 and third frame 3 are formed by two end plates 8 and two curb plates 9 combinations, have the mounting hole that forms circular installation cavity on two end plates 8, and two end plates 8 are connected through the curb plate 9 of both sides, are provided with a plurality of connecting rods 10 between two end plates 8, and a plurality of connecting rods 10 set up along circumference.

Based on the technical scheme, each independent base is formed by welding, each base is positioned only through the seam allowance and connected through the bolts, and the seam allowance plane can play a sealing role. The number of bolts can ensure sufficient strength, and the connecting rod 10 plays a role of reinforcing ribs to increase the strength in each independent seat.

Further, the bottom of the two end plates 8 are connected by angular connecting ribs 11 at two sides. The stability of the connection between the two end plates 8 is ensured while the contact area with the assembly plane is increased.

The utility model discloses fall into the three with the motor cabinet, possess following advantage: 1. the welding part is formed by welding each independent machine base, and the machine bases are divided into three parts, the motor is arranged at the same center, the first machine base and the third machine base are basically the same and can be used universally, the two parts are designed into standard parts, pre-production can be carried out in advance, and the production efficiency is improved. And the overall dimension becomes little, and welding operation is simple, needs auxiliary assembly less. 2. In the aspect of machining, because every part size is less, can process with more processing equipment, reduce the processing degree of difficulty, the assurance that machining precision can be higher also guarantees motor performance simultaneously. The motor can work normally and the motor can run normally. 3.
