Compared with a household blower, the commercial blower has the characteristics of high power, large air quantity, high air pressure and the like, and also has the characteristics of large volume and large weight to meet the requirements, so that the commercial blower motor is generally installed by adopting a circumferential suspension method, namely, a shell is arranged outside a stator core, 4 supporting ribs are uniformly distributed in the circumferential direction of the shell, and then the supporting ribs are installed in the whole machine. The installation mode has strong universality, and has the defects of large volume, heavy weight and high cost.

As shown in fig. 1, the conventional mounting structure of a commercial blower motor has the following disadvantages:

1. 4 mounting plates 100 perpendicular to each other are needed, and most of the mounting plates 100 are made of steel plates, so that the size is large, and the material consumption is high.

2. The motor needs a case 200, the mounting plate 100 needs to be welded on the case 200, the process is complex, the processing cost is high and the precision is low, and meanwhile, the case 200 also prevents the heat dissipation of the motor, so that the temperature rise of the motor is increased.

3. The mounting plate 100 is to be fixed in the housing, the screw holes 110 of the mounting plate are not positioned, the mounting plate is difficult to align with the mounting holes of the housing, the mounting plate needs to be repeatedly moved to calibrate the mounting holes, and the assembly efficiency is low.

Disclosure of Invention

In order to solve the problems, the utility model realizes the characteristics of small volume, light weight and low cost on the basis of firmness and reliability, and greatly saves social resources. The following technical scheme is adopted:

the mounting structure of the blower motor comprises a motor and a bottom supporting seat, wherein two sides of the bottom supporting seat extend struts and are fixed on an end cover of the motor through screws;

the bottom support seat is used for supporting and fixing the motor, and a hanging plate is arranged on one side of the motor, which is opposite to the bottom support seat.

Optionally, the contact surface of the bottom supporting plate and the motor is an arc surface, and the radian of the arc surface is the same as that of the matching surface of the stator core of the motor.

Optionally, a mounting surface of the bottom support plate is configured as a plane, and the mounting surface is configured to be mounted and fixed on an integral housing of the blower.

Optionally, the mounting surface is provided with a plurality of screw holes for screw locking and fixing.

Optionally, the suspension plate is screwed to an end cap of the motor.

Optionally, the suspension plate is welded to the end cap of the motor.

In summary, the utility model has the following beneficial effects:

1. the utility model adopts a split type stamping mounting structure structurally, realizes the characteristics of small volume, light weight and low cost on the basis of firmness and reliability, and greatly saves social resources.

2. The utility model adopts the bottom supporting seat and the hanging plate, and a shell is not required to be arranged outside the stator core of the motor, so that the utility model has simple process, low cost, quick heat dissipation and low temperature rise.

3. Compared with the traditional motor, the motor mounting structure designed by the utility model is lighter by more than 30% in weight, and the motor performance is more optimized.
