Method for controlling motor of air conditioner and motor controller of the same
First Claim
1. A motor controlling method of an air conditioner, comprising:
- determining whether or not an operating frequency of a compressor motor is the same as or greater than a predetermined frequency;
determining whether or not a detected velocity of a fan motor is the same as or lower than a predetermined velocity during a first time period; and
temporarily stopping the compressor motor if the operating frequency is greater than the predetermined frequency and the detected velocity is lower than the predetermined velocity during the first time period.

Abstract
A motor controlling method and apparatus of an air conditioner are disclosed. It is checked whether or not an operation frequency of a compressor motor is the same as or greater than a certain frequency and it is also checked whether or not a detected velocity of a fan motor is the same as or lower than a certain velocity during a certain time period. If the operation frequency is the same as or greater than the certain frequency and the detected velocity is the same as or lower than the certain velocity during a certain time period, the compressor motor is temporarily stopped. Because the compressor motor operates according to operational conditions of the fan motor, an overload can be prevented.
