Amplifier selection device, amplifier selection method, and computer-readable storage medium having power source capacity display function

An amplifier selection method, comprising:

• preparing a database containing a plurality of motor models expressing types of motors including servo motors and spindle motors along with information pertaining to an amplifier capacity and a feature amount for each of the motor models;
• obtaining information pertaining to the motor models selected for the spindle motors and the servo motors that drive respective spindle axes and servo axes;
• calculating necessary numbers of spindle amplifiers and servo amplifiers for each amplifier capacity by referring to the database and extracting information pertaining to the amplifier capacities of the selected motor models;
• selecting spindle amplifiers to drive the spindle motors on the basis of the amplifier capacities and number of spindle motors;
• creating a combination of spindle amplifiers and servo amplifiers corresponding to the necessary amplifier capacities and numbers, for each selected spindle amplifier;
• extracting information pertaining to a feature amount of each created combination of spindle amplifiers and servo amplifiers by referring to the database;
• determining a combination of spindle amplifiers and servo amplifiers on a basis of the extracted information pertaining to the feature amounts;
• calculating a capacity of a main power source necessary for driving the motors and a capacity of a control power source necessary for driving the spindle amplifiers and the servo amplifiers by referring to the database;
