| 20090072839 | Apparatus and method to detect failure of smoothing electrolytic capacitor - An apparatus and method to detect failure of an electrolytic capacitor that smoothes a DC voltage in an inverter circuit. The apparatus detects failure of a smoothing electrolytic capacitor in a motor drive inverter circuit that rectifies and smoothes an AC voltage through a rectifier and the smoothing electrolytic capacitor and converts a rectified and smoothed DC voltage into a 3-phase voltage to drive a motor. The apparatus includes a voltage meter, a current sensing unit, and a controller. The voltage meter measures a DC voltage of an inverter when the motor is not in operation. The current sensing unit measures a phase current of the motor when the motor is not in operation. The controller estimates an ESR value of the smoothing electrolytic capacitor from the DC voltage of the inverter and the motor phase current to detect failure of the smoothing electrolytic capacitor. | 03-19-2009 |
| 20100045226 | Method of controlling washing machine and motor - A method of controlling a washing machine and a motor determines whether a BLDC motor is in a normal state in software without hardware and a user is notified of an abnormal state of the BLDC motor if the BLDC motor is in an abnormal state, thereby ensuring safety. When the motor is rotated, the state of the motor is determined by applying harmonics to a voltage that is applied to a motor and analyzing an output frequency characteristic. When the motor is stopped, the state of the motor is determined by estimating the temperature of the motor. | 02-25-2010 |
