Abstract
In an apparatus and a method for controlling a compressor, by setting a stroke reference value so as to be smaller than a maximum stroke value in a maximum load state and operating the reciprocating compressor stably, damage of a reciprocating compressor can be prevented, a cost in a motor design can be reduced, and a size of a motor can be decreased in designing of the motor.
Claims22
In an apparatus for controlling a motor by being inputted power, an apparatus for controlling a compressor, comprising:
- a maximum stroke value determining unit comparing a maximum stroke value with an actual stroke value, varying a pre-stored stroke reference value and outputting the varied stroke reference value;
- and
- a compressor controlling a voltage inputted to an internal motor according to the varied stroke reference value.
A method for controlling a motor by being inputted power, comprising:
- comparing a maximum stroke value with an actual stroke value and outputting a comparison value;
- varying a pre-stored stroke value according to the comparison value;
- and
- controlling a voltage inputted to a motor according to the varied stroke reference value.
