Ceiling fan motor

Abstract

The invention discloses a ceiling fan motor, comprising a stator iron core, a coil and a shaft core; the coil is arranged in the stator iron core; the shaft core is arranged on the middle part of the stator iron core; the peripheral of the stator core is uniformly provided with magnets; the stator iron core is provided with fixing racks for fixing positions of the magnets; grooves re arranged inside the fixing racks; and the magnets are arranged inside the grooves. The beneficial effects of the ceiling fan motor are that: the fixing racks and the grooves are adopted for fixing magnets, which simplifies the structure, and the motor is light, which is easy to produce and transport by the current logistics; the ceiling fan motor adopts the magnets without the magnetic-conducting magnet yoke, which saves the energy and solves the problem that the prior art adopting the coil lacks of the excitation; the retaining screw is fixed on the outside of the magnet, which does not affect the magnetic path, the motor conversion rate is high and the operation is smooth; the groove structure is adopted to simplify the motor driving device operation processing; and the plastic fixing rack is adopted to enhance the security.

Description

technical field [0001] The invention relates to the technical field of a ceiling fan, in particular to a ceiling fan motor. Background technique [0002] A ceiling fan is a fan that is fixed on the ceiling and has a good cooling effect. The ceiling fan generally includes a ceiling fan motor and three fan blades fixed on the ceiling fan motor. The ceiling fan motor is used as a power source to drive the fan blades to rotate and generate a large The wind is used to cool off the heat, so the ceiling fan motor is the most important part of the ceiling fan. [0003] At present, the structures of existing ceiling fan motors are basically the same, and the principles are also basically the same. For example, the invention patent with the authorized notification number CN102163888A discloses a ceiling fan motor, whose components basically include the motor upper casing, the motor lower casing, the motor shaft, the motor stator, the motor rotor, the upper bearing, the lower bearing,...

For example, the invention patent with the authorized notification number CN102163888A discloses a ceiling fan motor, whose components basically include the motor upper casing, the motor lower casing, the motor shaft, the motor stator, the motor rotor, the upper bearing, the lower bearing, the motor upper casing and the motor A cavity is formed in the middle of the lower shell, the motor shaft runs through the upper shell of the motor and the lower shell of the motor and the motor stator, upper bearing and lower bearing are installed on the motor shaft from top to bottom, the upper bearing is fixedly connected with the inner wall of the upper shell of the motor, and the lower bearing is connected to the inner wall of the motor upper shell. The inner wall of the lower shell is fixedly connected, and the motor rotor is in interference connection with the inner walls of the upper motor shell and the lower shell of the motor at the same time. The motor rotor is located on the periphery of the motor stator and the inner wall of the motor rotor is attached to the outer wall of the motor stator. After power on, the motor stator is not fixed. The motor rotor rotates around the periphery of the motor stator and drives the motor upper shell and the motor lower shell to rotate. This motor structure is the common structure of most motors on the market. It basically meets the basic requirements of ceiling fans used in daily life. The effect of relieving heat, but this kind of motor is too traditional, so it cannot meet the requirements of modern society for low energy consumption, high efficiency, and high benefit. However, this ceiling fan motor still has some shortcomings. 1. The motor structure is complex and inconvenient to disassemble. The overall internal space is loose, resulting in a large and uncompact motor; 2. Due to the large overall volume of the motor, the weight of the motor is relatively large, so the energy consumption of the motor is high during operation, and the cost of use increases; 3. Due to the structure Complexity leads to complex production process of the motor and low overall production efficiency; 4. The motor structure and production process are complex, resulting in loss of raw materials, high production energy consumption and high production cost
