ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP2023011457
Kind Code:
A
Abstract:
To provide an electric motor which easily forms a current path through which noise current in a stator core flows to a case.SOLUTION: There is provided an electric motor 10 comprising a stator 30 having a stator core 32 in which a plurality of electromagnetic steel sheets is laminated in a motor axis CLm direction and a winding 52 wound around the stator core 32, a rotor 20 radially facing the stator 30, and a case accommodating the stator 30 and the rotor 20. (a) Each of the electromagnetic steel sheets is provided with a caulking part 60 that can be fixed relatively immovably, (b) the plurality of electromagnetic steel plates is laminated so as to be electrically connected to each other through the caulking part 60, and (c) the plurality of electromagnetic steel sheets electrically connected to each other via the caulking part 60 is electrically connected to the case.SELECTED DRAWING: Figure 1
