Problems solved by technology

However, after using a plastic-encapsulated motor, the plastic-encapsulated compound itself is insulated, and other components in the air-conditioning system cannot be grounded through the motor. Additional methods are required to achieve the purpose of grounding, which will increase the complexity and manufacturing cost of the air-conditioning system.

Embodiment Construction

[0023] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 A plastic-sealed motor with a mounting foot grounding structure shown includes a motor 1 , a mounting foot 2 integrally formed with the motor, and a grounding metal piece 3 . The motor 1 is a plastic-sealed motor with mounting feet 2, the motor is installed on the air conditioner body, and the bottom surface 21 of the mounting leg is in contact with the mounting plate 5 of the air conditioner body. The ground metal piece 3 is fixed on the bottom surface 21 of the installation foot 2, and is higher than the bottom surface of the installation foot. When the motor 1 is installed on the air conditioner body, the ground metal piece 3 is used as the installation plate between the bottom surface of the installation foot and the air conditioner body. 5 contacts. The grounding metal piece 3 has a groundi...

Abstract

The invention discloses a plastic packaging motor with a mounting foot grounding structure and belongs to the technical field of motors. At present, after using the plastic packaging motor, the molding compound is insulated, other components in an air conditioner system cannot connect with the ground through motors, the grounding should be realized through additional modes, and this would increase the air conditioner system complexity and manufacturing cost. The plastic packaging motor with the mounting foot grounding structure comprises a motor body and a mounting foot for mounting the motor body and is characterized in that the mounting foot is provided with a grounding metal piece, and the grounding metal piece realizes grounding through a ground wire connected with the same. According to the technical scheme, the grounding of the air conditioner system is realized through arranging the grounding metal piece at the mounting foot, the structure is simple, the plastic packaging motor has the consistent safety effect with a steel shell motor, and moreover, the mounting foot is provided with the grounding metal piece so that the connecting intensity between the plastic packaging motor and air conditioner body can be improved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a plastic-sealed motor with a grounding structure for mounting feet. Background technique [0002] The plastic-encapsulated motor itself has an insulating structure and does not need to be grounded. However, according to the safety requirements of 3C certification, the entire air conditioning system needs to be grounded. In the past, when steel-cased motors were used, the steel plates used in the steel case were metal parts and had their own grounding wires. Other components in the air-conditioning system that needed to be grounded were connected to the grounding wire through the mounting plate, the steel case, and formed a loop, so that the entire air-conditioning system grounded. After using a plastic-encapsulated motor, the plastic sealing compound itself is insulated, and other components in the air-conditioning system cannot be grounded through the motor. Additional methods...
