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.
Claims13
An apparatus that controls driving of a linear motor, comprising:
- a detector that detects a current applied to the linear motor;
- a controller that outputs a control signal based on the detected current;
- and
- a switch that varies the number of windings of a linear motor coil on the basis of the control signal,
- wherein the linear motor comprises a first coil wound with a first predetermined number of windings and a second coil wound with a second predetermined number of windings and connected to the first coil in series.
