Description

Ventilation fan motor Technical Field The utility model belongs to the technical field of motors, and particularly relates to a ventilator motor. Background The ventilator is an air-conditioning electric appliance which drives fan blades to rotate by a motor to drive air flow, so that indoor and outdoor air exchange is realized, and the ventilator is mostly applied to a relatively closed space. The existing ventilator motor is generally coated with the stator by the two half-shells, so that internal heat is not easy to radiate outwards, and the normal operation of the motor is affected due to high temperature. The prior art patent document (bulletin number: CN 216111396U) discloses a ventilating fan motor, and the technical problems are also existed. Disclosure of Invention The utility model aims to solve the technical problems in the prior art and provide the ventilating fan motor which is novel in structure, high in heat dissipation efficiency, positioning and butt joint, simple to assemble and high in practicability, and a stator is designed in an exposed mode. In order to solve the technical problems, the utility model adopts the following technical scheme: A ventilator motor comprises a motor body and is characterized in that the motor body comprises a stator, a first end cover and a second end cover, a first lug seat is arranged on the peripheral wall of the first end cover, a second lug seat is arranged on the peripheral wall of the second end cover, the first lug seat is in contact with one end face of the stator, the second lug seat is in contact with the other end face of the stator, so that the first end cover is positioned and sleeved at one end of the stator, the second end cover is positioned and sleeved at the other end of the stator, and a fastener is connected between the first lug seat and the second lug seat, so that the first end cover is matched with the second end cover to clamp the stator. The motor is novel in structure, the stator is of an exposed design, the heat dissipation efficiency is high, the positioning and the butt joint are achieved, the assembly is simple, and the practicability is high.
