Energy-saving motor for bath heater

Abstract

The invention discloses an energy-saving motor for a bath heater, and aims to provide a simple, reasonable, stable, reliable, energy-saving and noise-reducing energy-saving motor for a bath heater, wherein the motor comprises an upper casing, a lower casing, a rotating shaft fixedly arranged in the centers of the upper casing and the lower casing, a rotor assembly, a stator assembly, an upper bearing and a lower bearing; the upper casing and the lower casing are buckled with each other; the upper bearing and the lower bearing are matched at two ends of the rotating shaft; the stator assembly is sleeved outside the rotor assembly. The motor is characterized in that the two ends, corresponding to the upper bearing and the lower bearing, of the rotating shaft are concave inwards respectively to form arc connection grooves, an upper bearing seat matched with the upper bearing is arranged in the upper casing in a concave mode, and a lower bearing seat matched with the lower bearing is arranged in the lower casing in a concave mode; a wave-shaped gasket for fixing the upper bearing on the rotating shaft is arranged in the upper bearing seat, and a limiting gasket for fixing the lower bearing on the rotating shaft is arranged in the lower bearing seat.

Description

technical field [0001] The invention relates to the technical field of motors for bathroom heaters, in particular to an energy-saving motor for bathroom heaters. Background technique [0002] In the absence of heating, especially in the southern region, Yuba should be regarded as a must-have electrical appliance for every family. With the upgrading of heating technology, the functions and quality are becoming more and more perfect, and the ownership rate of Yuba in Chinese families is also increasing year by year. At present, the mainstream Yuba on the market can be divided into two types: one is the more traditional light bulb Yuba, which uses high-intensity light for heating; Blessing, blowing warm wind for heating. [0003] The motor is the core of the Yuba motor. The smart Yuba motor takes into account the functions of heating, ventilation, and drying. Most of the research on the traditional Yuba motor focuses on the motor speed, torque, and low-voltage control. The tr...

Problems solved by technology

[0003] The motor is the core of the Yuba motor. The smart Yuba motor takes into account the functions of heating, ventilation, and drying. Most of the research on the traditional Yuba motor focuses on the motor speed, torque, and low-voltage control. The traditional Yuba motor has the following problems: 1. The upper and lower bearings in the motor have a gap insertion structure, which is easy to move up and down, resulting in high noise; 2. When the current applied to the motor is too large, it may cause the permanent magnet of the motor to appear permanently on the edge of the excitation coil. Demagnetization, high energy consumption of the motor, can not work normally in the long run, directly shortening the service life of the motor
