Title:
MOTOR
Document Type and Number:
Japanese Patent JP2018050359
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor in which power consumption, cost, and space are reduced.SOLUTION: A close loop coil 22 is arranged so as to be close to an open loop coil 21, and an amount of capacitors C1 and C2 connected to the open loop coil 21 and the close loop coil 22 is set so that resonance frequencies of the open loop coil 21 and the close loop coil 22 are matched. Thus, a magnetic field is magnetically coupled between the open loop coil 21 and the close loop coil 22, and is resonated. A current larger than the current inputted to the close loop coil 22 flows, and the larger magnetic filed is generated. Thus, a rotor 3 can be rotated by the low power consumption. A sine wave of a specific frequency can be obtained by a resonance phenomenon, and the circuit for generating the sine wave can be simplified.SELECTED DRAWING: Figure 1
