Current to frequency converter, evaluation apparatus, evaluation method, and recording medium thereof

PURPOSE: A current frequency transforming device, a device for assessing a device to be corrected, a method thereof, and a recording medium are provided to implement in a room temperature, not using a refrigerant. CONSTITUTION: A current input unit(100) receives the input of a current from a current source(10) providing a source current. A motor(200) includes a permanent magnet and a coil is rotated by the source current. An attenuator(300) generates a rotary friction coefficient proportional to the magnetic flux density of the motor. A frequency output unit(400) outputs the frequency which corresponds to the source current depending on the rotation of the motor. [Reference numerals] (100) Current input unit; (200) Motor; (300) Attenuator; (400) Frequency output unit
