Laundry machine having induction heater and control method of the same

A laundry machine comprising:

• a tub;
• a drum that is rotatably mounted in the tub and that is configured to receive laundry;
• an induction heater that is located on the tub and that is configured to heat the drum;
• a motor that is configured to rotatably drive the drum;
• and
• a user interface comprising:
• a course selection unit that is configured to select one of a plurality of courses,
• an option selection unit that is configured to select an option that corresponds to the selected one of the plurality of courses, and
• a processor that is configured to control a spinning speed of the drum and that is configured to drive the induction heater,
• wherein the processor is configured to determine whether to perform a heat-spinning operation or a normal spinning operation based on a selected course, the heat-spinning operation being configured to perform spinning and heating the drum and the normal spinning operation being configured to perform spinning the drum without heating,
• wherein the processor is configured to, based on the heat-spinning operation being performed, calculate an instantaneous power of the motor and determine an output of the induction heater differently based on the calculated instantaneous power of the motor and a predefined upper power limit of the laundry machine.
