Compressor

A compressor comprising:

• a compressor body that compresses gas;
• a motor that drives the compressor body;
• a control device that controls the motor;
• and
• a current sensor that detects a current value of the motor,
• wherein the control device is configured to:
• compute, through the current sensor, a current value I1 of the motor at a point in time when a first time has elapsed from a start of the motor and a current value I2 of the motor at a point in time when a second time, longer than the first time, has elapsed from the start of the motor, and
• make a first notification corresponding to a first mode in a case where a following equation (1) is established, and make a second notification corresponding to a second mode in a case where a following equation (2) is established for a first threshold value I1limit that is smaller than a current value obtained at the start of the motor and larger than a rated current value of the motor and a second threshold value I2limit that is smaller than the first threshold value I1limit and larger than the rated current value of the motor, wherein equation (1) and equation (2) are as follows:
