A refrigerator having an inner case that constitutes a storage compartment, an outer case that is coupled to an outer side of the inner case and constitutes an exterior, and a connector that connects a flexible flat cable (FFC) and wires. The connector includes a first housing having an accommodation space in which the FFC is inserted, a plurality of second housings in which a wire insertion hole into which the wires are inserted, is formed and which are coupled to the first housing, and connection members provided in the first housing and the plurality of second housings so as to electrically connect the FFC and the wires. The connector is installed at the inner case in such a way that the first housing faces the outer case and the second housings face the storage compartment.

A BLDC motor phase commutation method is provided, which can correctly detect phase commutation timing and position detection timing of a BLDC motor in a compressor to stabilize rotation and RPM of the compressor, thereby minimizing noise and vibration. When the BLDC motor rotates through a mechanical angle corresponding to one period, the BLDC motor operates according to a first scheme in which operation of the BLDC motor in the first phase commutation section of a period is performed in the same manner as in the last phase commutation section of a period immediately prior to the period. After the BLDC motor switches to sensorless mode, the BLDC motor operates according to a third scheme in which the first phase commutation section of a period has a time interval equal to the average of time intervals of first phase commutation sections of periods prior to the period.

Phase commutation method of brushless direct current motor

A Brushless Direct Current (BLDC) motor starting method and device are provided. With the method and/or device, startup noise and vibration and startup failure rate can be reduced using a constant low-speed startup scheme when the BLDC motor is in startup mode. Additionally, Pulse Width Modulation (PWM) duty is also maintained at low level when the BLDC motor starts up, thereby preventing excessive current from occurring due to desynchronization of the motor at startup, so that it is possible to optimize specifications of an inverter in the BLDC motor. The BLDC motor starts up with a synchronous speed and a PWM duty of a rotor of the BLDC motor being kept constant, and the BLDC motor switches to sensorless mode if a position of the rotor is detected a predetermined number of times or more during a specific time period.

Device and method for starting brushless direct current motor

A refrigerator including a control unit for a condenser fan in connection with operation of a compressor if an outdoor temperature sensor is out of order. Since the condenser fan is driven in connection with the operation of the compressor, a trip phenomenon of the compressor generated due an overload of the compressor can be prevented, which results in stable operation of the refrigerator as well as increased reliability of the refrigerator.
