Title:
A machine learning device and a magnetizing device for electric motors
Document Type and Number:
Japanese Patent JP6140236
Kind Code:
B2
Abstract:
A machine learning system according to an embodiment of the present invention includes a state observer for observing the winding temperature, winding resistance, current value, and rotor magnetic flux density of a magnetization unit having a magnetizing yoke and windings; a reward calculator for calculating a reward from the rotor magnetic flux density obtained by the state observer; and a learning unit for updating an action value table based on a magnetization rate calculated from the rotor magnetic flux density and a target magnetic flux density, the winding temperature, and the winding resistance.
