摘要： A high-pressure washing machine is provided, which can stop a brushless motor even if the function of a microcomputer declines. The high-pressure washing machine is provided as a high-pressure washing machine 10 having a pump 12 which sucks and discharges a washing solution and a brushless motor 14 supplied with current to drive the pump 12. The high-pressure washing machine 10 includes an inverter circuit 29 which when the pump 12 driven by power from the brushless motor 14 discharges the washing solution, controls the rotation speed of the brushless motor 14, a driver circuit 30, a microcomputer 31, and a motor operation stopping circuit 37 which detects the discharge pressure of the pump 12 and which based on the result of the detection, switches on and off an electric circuit E1, which supplies current to the brushless motor 14.

摘要： An impact tool capable of improving durability of tool components and capable of reducing noise and vibration is provided. The impact tool includes a housing, a motor, a motion converting portion, an output portion, a power supply portion, a load detecting portion, and a control portion. The motor is disposed in the housing. The motion converting portion is configured to convert a rotating motion of the motor into a reciprocating motion. The output portion is configured to output the reciprocating motion of the motion converting portion as an impact force. The power supply portion is configured to supply a driving power to the motor. The load detecting portion is configured to detect a load imposed on the motor. The control portion is configured to control the power supply portion to increase the driving power supplied to the motor during a prescribed period when the load detected by the load detecting portion is larger than a prescribed value.
