Title:
MAGNETIC DEVICE, DC MOTOR, DC BRUSHLESS MOTOR, AND VOICE COIL MOTOR
Document Type and Number:
Japanese Patent JP2023081077
Kind Code:
A
Abstract:
To parallelly connect a plurality of electromagnetic coils to be applied to any type of a motor, and suppress DC voltage to be applied to the connected electromagnetic coils, whereby power consumption during driving of an electromagnetic device is reduced.SOLUTION: A magnetic device includes a plurality of coils that is obtained by winding one coil which is formed by winding an electric wire by M turns around a prescribed-length core, around N split cores by M/N turns equally, and a power source that parallelly connects the coils of the electric wires wound around the respective cores, and applies equal DC voltage between the coils. In the power source, a DC voltage that is applied to each of the coils is lower than a DC voltage that is applied to the one coil.SELECTED DRAWING: Figure 1
