Abstract

The invention discloses a low-noise fan motor, which comprises a motor shell and an air guide sleeve, the air guide sleeve is arranged on the top side of the motor shell, the air guide sleeve is formed at a top end opening of the motor shell in an overhead mode from the motor shell, and a bearing positioning frame is arranged at the position, close to the bottom edge, of the inner side of the air guide sleeve, the bearing positioning frame is integrally formed in the air guide sleeve, a PCB main board is arranged on the top side of the bearing positioning frame, main board positioning rods are arranged at the corners of the PCB main board in the vertical direction, the main board positioning rods are positioned at the corners of the PCB main board in a penetrating mode, and an upper fixing bearing is arranged on the inner side of the bearing positioning frame and located at the circle center, and the upper fixing bearing is embedded into the inner side of the bearing positioning frame from the port of the bearing positioning frame.

Description

technical field [0001] The invention belongs to the technical field related to motors, and in particular relates to a low-noise fan motor. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy. It uses a energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force. The motor is divided into DC motors and AC motors according to the power supply used. The motors in the power system are large Part of it is an AC motor, which can be a synchronous motor or an asynchronous motor. The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line. [0003] The existing fan motor technology has the following problems: the existing fan motor is mostly based on passive heat dissipation to dissipate heat from the main body of the motor, so motor u...
