电机、空调器及其控制方法

Motor, air-conditioner and control method thereof

Abstract

The invention provides a motor, an air-conditioner and a control method thereof. The motor comprises a casing, a rotary shaft, a rotor part, a stator part and more than one bearing. The end portion of the motor is provided with an end cover, the rotary shaft is connected with the rotor part, and the outer end of the rotary shaft penetrates the end cover and extends towards the outside of the casing. The bearings are installed on the rotary shaft and located in a connection region of the rotary shaft and the end cover. The motor is further provided with a bearing heating device. An environment temperature sensing device of the air-conditioner and the motor are electrically connected with a control device. The control device of the air-conditioner judges whether the outdoor temperature is lower than the set temperature T or not, and meanwhile judges whether the air-conditioner is in an operation state or not. When the outdoor temperature is lower than the set temperature T and the air-conditioner is in a shutdown state, the bearing heating device is started. A problem that the motor of the air-conditioner cannot be started due to lubricating grease solidification is solved, the cost improved by grease replacement is reduced, and the reliability of a unit operating under the low-temperature condition is improved.
本发明提供了一种电机、空调器及其控制方法,由于电机,包括有壳体、转轴、转子部件、定子部件以及一个以上轴承;所述电机的端部设置有端盖,转轴与转子部件连接,转轴的外端穿过端盖向壳体外伸出;轴承安装在转轴上,并位于转轴与端盖的连接区域;电机还设置有轴承加热装置;空调器的环境温度感温装置以及电机均与控制装置电气连接;空调器的控制装置判断室外温度是否低于设定温度T,同时,空调器的控制装置判断空调器是否处于正在运行状态;当室外温度低于设定温度T且空调器处于关机状态时,开启轴承加热装置。解决了空调器的电机由于润滑油脂凝结导致的无法启动现象,降低由于油脂的更换提高的成本,增加机组在低温情况下运行的可靠性。
