Abstract
An apparatus and method for controlling driving of a linear motor, which is configured to increase efficiency of a linear compressor and stably drive the linear motor when the linear motor is overloaded. The apparatus includes a detector that detects a current applied to a motor, a controller that outputs a control signal based on the detected current and a switch that varies the number of windings of the linear motor coil on the basis of the control signal.
