  • Publication number: 20190272952
    Abstract: A magnetic core includes a winding core and first and second flanges connected to the winding core. First and second terminal electrodes are connected to a lead frame. The first flange is bonded to the first and second terminal electrodes. Third and fourth terminal electrodes are bonded to the second flange. First and second insulation-coated conductive wires are wound about the winding core. The first and second insulation-coated conductive wires are connected to the first and second terminal electrodes and the third and fourth terminal electrodes. The lead frame is bent so as to rotate the magnetic core by 90 degrees with respect to the lead frame. A magnetic plate is bonded to the magnetic core. The magnetic core is removed from the lead frame by removing the first and second terminal electrodes from the lead frame, thereby providing a common-mode choke coil. The common-mode choke coil having stable electrical performance is produced efficiently by the above method.

  • Publication number: 20190222152
    Abstract: In one implementation, a motor module according to the present invention includes: a motor driving circuit 10 to drive a motor M; and a position estimation device 30 to output an estimated position signal of a rotor R of the motor M. It also includes: a motor control circuit 20 to supply a command voltage value to the motor driving circuit 10 in response to a pulse signal; and a variable step-size memory 40 storing variable step-size information, which defines an amount of displacement of the rotor R per pulse of the pulse signal. The estimated position signal is an analog or digital signal. Upon receiving a pulse signal, the motor control circuit 20 determines the command voltage value based on an estimated position value of the rotor R acquired from the position estimation device 30 and the variable step-size information read from the variable step-size memory 40. The motor driving circuit 10 changes the position of the rotor R based on the command voltage value.
