A motor includes a motor part and an amplifier configured to supply electric power to the motor part. The motor part includes a stator and a rotor. The amplifier includes a first frame constituting a housing of the amplifier and a second frame. The second frame is arranged on a first face located in a direction perpendicular to a rotation axis direction of the rotor at the first frame. At least one substrate housed in the first frame is attached to the second frame.

Motor and producing method for motor

A motor controller which is inexpensive and has high cooling performance by using an extrusion heat sink (), reducing the number of parts, and reducing the man-hours of assembling is provided. In a motor controller including an extrusion heat sink (), and a power semiconductor module () including a plurality of external electrode terminals which closely contact the extrusion heat sink (), and a printed circuit board having the plurality of external electrode terminals connected thereto, die-casting frames () in which a pedestal () for attaching a motor controller and bosses () for attaching a printed circuit board are molded are provided at both ends of the extrusion heat sink ().

Motor controller

A motor controller capable of relaxing the temperature of a heat source which generates heat by driving the motor controller, and capable of realizing miniaturization and low price is provided. In a motor controller in which a power semiconductor module () which closely contact a heat sink () is mounted on a substrate (), and a fan () is attached to the heat sink () by a fan case (), portions of fins () of the heat sink () are formed with a bell mouth () and a circular-arc-shaped guide (), and the radiating capability of the fins () is improved by effectively using the wind of the fan ().
