Abstract
A compressor capable of reducing oil foaming and reducing the waiting time taken until the heating of the compressor is completed, and a method of controlling the same, the method of controlling a compressor including sensing temperature of the oil in the compressor, if the temperature of the oil is below a reference temperature, performing a loss operation, in which an amount of heat radiation of the motor part is increased, while operating the motor part at a low speed, and if the temperature of the oil increases to be equal to or higher then reference temperature, performing an efficiency operation by converting an operation of the motor to a normal operation.
