| 20100010676 | APPARATUS AND METHOD FOR CONTROLLING DRIVING OF FAN MOTOR FOR REFRIGERATOR - Disclosed is an apparatus and a method for controlling a driving of a fan motor for a refrigerator. In a normal driving mode that a temperature of the inside of the refrigerator is higher than a predetermined temperature, the fan motor is driven in a normal speed, and in a waiting mode that the temperature of the inside of the refrigerator is lower than the predetermined temperature, the fan motor is driven in a driving speed very lower than that of the normal driving mode, without stopping of the fan motor, accordingly it is capable of preventing moisture introduced into the fan motor from being frozen, thereby preventing the fan motor from being locked. | 01-14-2010 |
| 20100014995 | OUTER ROTOR TYPE FAN-MOTOR - An outer rotor type fan-motor includes: a rotational shaft; a bearing assembly that rotatably supports the rotational shaft; a stator installed at an outer side of the bearing assembly; a permanent magnet assembly that covers an outer side of the stator at a certain distance and is installed at the rotational shaft; and a fan that includes a shaft fixing part for fixing the rotational shaft, a hub for covering an outer side of the permanent magnet assembly at a certain distance and blades formed around the hub. An insulation space is formed between the permanent magnet assembly and the fan to prevent transfer of vibration and noise of the permanent magnet assembly to the fan, and vibration or noise of high frequency can be reduced. | 01-21-2010 |
| 20100017039 | DRIVE CONTROL APPARATUS AND METHOD FOR REFRIGERATOR TYPE FAN MOTOR - An apparatus and method for controlling driving of a fan motor for a refrigerator are disclosed. When operated, a plurality of fan motors provided in a refrigerator are sequentially operated at certain delay times, to thus improve operation efficiency of the plurality of fan motors. The apparatus for controlling driving of a fan motor includes: at least one blowing unit that supplies cool air; a driving unit that generates a drive signal for driving the blowing unit; a control unit that controls operation of the driving unit; a power unit that provides operation power of the driving unit and the control unit; and a cut-off unit that is positioned between the driving unit and the power unit and cuts off noise and a surge voltage introduced from the power unit to the driving unit. | 01-21-2010 |
| 20100064719 | FAN MOTOR ASSEMBLY FOR BLOWING COOLING AIR AND REFRIGERATOR HAVING THE SAME - A cool air supplying fan motor assembly and a refrigerator having the same are disclosed. According to the cool air supplying fan motor assembly and the refrigerator having the same, because the fan motor assembly is configured to be compact, the capacity of a storage space of the refrigerator can be increased, and because a power line that supplies power to the motor does not interfere with the flow of cool air, the refrigerating efficiency of the refrigerator can be increased and vibration and noise can be minimized. | 03-18-2010 |

| 20090043426 | Apparatus and Method for Controlling Fan Motor of Air Conditioner - An apparatus for controlling a fan motor of an air conditioner comprises: a hybrid induction motor (HIM) for discharging warm air outwardly by a control signal; a temperature detecting unit for detecting a temperature of an evaporator; and a controlling unit for comparing the temperature of the evaporator with a preset temperature, and outputting a control signal to control the HIM based on a result of the comparison. | 02-12-2009 |
| 20100026126 | OUTER ROTOR-TYPE FAN MOTOR AND METHOD FOR MAGNETIZING MAGNET APPLIED THERETO - An outer rotor-type fan motor and a method for magnetizing a magnet applied thereto. The outer rotor-type fan motor comprises a rotation shaft; a stator disposed outside the rotation shaft; a fan having a hub and blades formed on the hub, the hub covering the stator with a predetermined gap; and a magnet disposed on an inner surface of the hub and spaced from the stator with a predetermined gap, wherein the magnet is an isotropic magnet magnetized to have a pole anisotropy. Accordingly, a cogging torque and noise are reduced without reducing a back-electromotive force, thereby obtaining a high efficiency. | 02-04-2010 |
