摘要： An electric power tool is configured to control power supply to a motor based on an operational amount of the variable speed switch, and further configured to perform in an intermittent control mode in which power supply to the motor is varied intermittently in the same manner as if an ON operation and an OFF operation of the variable speed switch were repeated. It is also able to perform in a continuous control mode in which power supply to the motor is varied based on the operational amount of the variable speed switch.

摘要： A trigger switch has a case member, a cover member, and an operation member configured to be used to carry out an operation. The case member and the cover member are combined with each other to form a waterproof case. When the operation member is operated, the operation member is displaced inward of the waterproof case. An internal pressure of the waterproof case changes in accordance with displacement of the operation member. The case member has a case base that is made from an inelastic body. The case base does not deform in accordance with a change in internal pressure of the waterproof case. The case base has at least one hole part. The case member has at least one deformation section that seals the at least one hole part. The deformation section is made from an elastic body.

摘要： A motor controller comprises a processor selectively outputting an on-signal to either one of an upper arm switching element and a lower arm switching element based upon a detected position by the position sensor, gate drivers inputting a driving voltage to the gates of the switching elements by shifting a level of the on-signal from the processor to the upper arm switching element and a bootstrap capacitor configured to be charged while the upper arm switching element is turned off and to behave as a voltage supply for the gate driver while the upper arm switching element is turned on. The processor is configured to reduce a set duty ratio when the set duty ratio is equal to or larger than a predetermined value (e.g. 80 percents) and a rotational position of the motor does not change for a first predetermined time. This motor controller can prevent the switching element from a burnout even if the motor is locked.
