A motor drive apparatus includes a bus bar through which a current associated with motor driving flows, a printed circuit board, and a conductive support pedestal mounted on the printed circuit board and interposed between the bus bar and the printed circuit board, wherein the conductive support pedestal includes at least one hole for screw passing configured to fasten the bus bar and the conductive support pedestal with screw tightening, and a terminal unit for a printed circuit board configured to electrically connect an electric wire provided in the printed circuit board to the conductive support pedestal.

Motor drive apparatus including bus bar

A motor drive apparatus includes: a power device constituting a portion of a power conversion circuit for generating electric power for driving a motor and having input/output terminals; a printed wiring board having a hole; a bus bar connected to both of the power device and the printed wiring board, wherein the bus bar includes a first plate-like connector portion to be fixed to the input/output terminal, a second connector portion to be connected to the printed wiring board, and an extension portion extending between the first connector portion and the second connector portion that will pass through the hole.

Motor drive apparatus having electric power flowing into/out of power device through bus bar

A motor driving device includes: a printed circuit board; a surface mounted component group of multiple surface mounted components surface-mounted on a printed surface of the printed circuit board; a heat-generating component group of multiple heat-generating components that generate an amount of heat equal to or larger than a predetermined amount, the heat-generating component group being provided on the printed surface side of the printed circuit board; a fan configured to blow air to the heat-generating component group to thereby cool the heat-generating components; and a cover configured to block flow of air blown by the fan so that the air blown by the fan will not flow to the surface mounted components.

Motor driving device

An amplifier selection device includes: a storage configured to store identification information and specifications of motor and amplifier; a display controller configured to display a motor selection command input section and a motor list; a motor selector configured to select a motor in accordance with a selection command; an amplifier selector configured to select an amplifier that satisfies specifications of a motor; an accessory information storage configured to store identification information of an accessory, identification information of an amplifier compatible with the accessory, and supplementary information; an accessory selector configured to select an accessory compatible with a selected amplifier by referring to the accessory information storage; and an accessory list display controller configured to display an accessory list of a selected accessory; wherein the display controller is configured to display a wiring diagram including the selected accessory, an amplifier, and a motor connected together.

Amplifier selection device comprising accessory selecting function

A motor driving device includes a control circuit board provided with a control circuit configured to output a control signal of a secondary voltage and a power circuit board provided with power circuitry to which a primary voltage higher than the secondary voltage is applied. The power circuit board includes a first substrate provided with a primary voltage component group to which only the primary voltage is applied, and a second substrate provided with a converter component group configured to convert the primary voltage into the secondary voltage and convert the secondary voltage into the primary voltage.
