Problems solved by technology

[0002] In order to dissipate the heat continuously generated during operation, modern general-purpose AC asynchronous motors often adopt an open structure to solve the internal heat dissipation problem in some relatively clean environments, but the motors used in most occasions generally do not allow the use of open structures. Only rely on the wind teeth attached to both ends of the rotor to stir the air flow inside the body to dissipate heat for the rotor, and at the same time install an external fan at one end of the closed body to dissipate heat for the motor as a whole

Embodiment 1

[0015] Figure 4 is in image 3 On the basis of adding an electromagnetic valve controlled by the electromagnet to open and close, the overall structure of the inner shielding assembly with the electromagnetic valve is formed. When the motor is not working, the valve 4 closes the passage of the shielding plug 1 due to the pressure control of the spring 6; when the motor is started, the electromagnet pulls the valve 4 to open the passage of the shielding plug.

Abstract

The invention relates to an electromagnetic-operation internal shielding assembly for a motor with an internal shielding ventilation opening. An internal shielding component comprises a shielding plug provided with a plurality of inclined ventilation guide plates arrayed parallelly and a position-adjustable installation clamp plate. The electromagnetic-operation internal shielding assembly comprises the component and an electromagnetic valve.

Description

technical field [0001] The invention relates to an electromagnetic opening and closing inner shielding assembly for a motor with an inner shielding vent. Background technique [0002] In order to dissipate the heat continuously generated during operation, modern general-purpose AC asynchronous motors often adopt an open structure to solve the internal heat dissipation problem in some relatively clean environments, but the motors used in most occasions generally do not allow the use of open structures. Only rely on the wind teeth attached to both ends of the rotor to stir the air flow inside the body to dissipate heat for the rotor, and at the same time install an external fan at one end of the closed body to dissipate heat for the motor as a whole. The patented technology "High Efficiency and Energy Saving Motor with Inner Shielding Vents" has greatly enhanced the internal cooling capacity of the motor due to the function of the vents, and improved the cooling capacity of th...
