Abstract: A motor drive system enabling detection of cutting fluid deposited at a housing of electronic components. A housing holding electronic components of a motor drive system has top faces slanted with respect to the horizontal plane so as to guide the deposited cutting fluid. The housing further includes storage parts collecting the cutting fluid guided along the top faces. The storage parts may be graduated so as to enable the collected amount of the cutting fluid to be measured. The storage parts may be configured to be detachable from the housing.

Abstract: A motor drive device is capable of allowing a user to surely recognize that effect when a cutting fluid adheres to a casing. The motor drive device includes an electronic component and a casing that houses the electronic component. A part of the casing changes color when coming in contact with a cutting fluid and the casing may change to different colors based on the concentration of the cutting fluid.

Abstract: A compact motor-drive unit wherein each component can be stably fixed to the unit. A motor-drive unit has a plurality of substrates each having a circuit for driving a motor; semiconductor devices mounted on the respective substrates; at least one smoothing capacitor mounted on at least one of the substrates; and a heat radiator having a heat-transferring surface adjacent to the semiconductors. The smoothing capacitor is positioned within a swept area formed by moving the first substrate arranged generally parallel to a base surface, in a counter-front direction, so that the smoothing capacitor is separated from the first substrate.

Abstract: A PWM signal generation unit generates a PWM signal to drive a motor, based on a current value of the motor sampled by a current value sampling unit, a position or speed of the motor sampled by a motor sampling unit, and a position or speed of a driven object sampled by a driven object sampling unit. An operation stop unit stops the operation of any one of the motor sampling unit and the driven object sampling unit depending on the power stored in the DC link part and power to which the control power source can supply when the alternating-current power source fails.
