An electric working machine in one aspect of the present disclosure includes: a motor; a controller for controlling driving of the motor; a first setter; and a second setter. The first setter is operated for setting, as a control method for the motor, which is usable by the controller, one of control methods preliminarily registered. The second setter is operated for setting, as a control method for the motor, which is usable by the controller, at least one of the control methods settable via the first setter.

Electric working machine

An electric working machine in one aspect of the present disclosure includes: a motor, a manipulator, a setter, and a controller. The setter sets first control characteristics preliminarily registered. The first control characteristics are set to achieve a rotational speed of the motor from a minimum rotational speed to a maximum rotational speed with a manipulating range of the manipulator, which is 50% or less of an effective manipulating range thereof.

An electric power tool may include a three-phase brushless motor configured to drive a tool, a gear reducer provided between the motor and the tool. The gear reducer is configured to selectively change a reduction ratio from the motor to the tool between a first reduction ratio and a second reduction ratio. The electric power tool may further include a motor controller configured to drive the motor with rectangular waves. The motor controller is configured to selectively change a conduction angle of each rectangular wave between at least a first conduction angle and a second conduction angle.

Electric power tool

An electronic power equipment, which is configured to be connected to both an AC power source and a DC power source, has a motorconfigured to be driven by both AC power and DC power, an AC circuitfor supplying AC electric power to the motora DC circuitfor supplying DC electric power to the motorswitching parts RL-RLfor switching between the AC circuitand the DC circuitwherein the AC and DC circuits are insulated relative to each other, and a controller Aconfigured to control the switching parts RL-RLthe AC circuitand the DC circuit

Electronic power equipment

A work machine includes an operation rod, a front unit disposed at a front end of the operation rod and configured to attach a tool, a rear unit disposed at a rear end of the operation rod and configured to attach a battery, a brushless motor disposed in the front unit and configured to drive the tool, a motor controller disposed in the rear unit and electrically coupled with the battery, and a plurality of motor power lines disposed along the operation rod and configured to electrically couple the motor controller with the brushless motor.

A rotary impact tool includes: a hammer rotating by receiving a rotational force of a motor; an anvil rotating by receiving a rotational force of the hammer; and an end tool attached to the anvil, the rotary impact tool being constructed such that when a torque of a value not less than a predetermined value is applied to the anvil from the outside, the hammer is disengaged from the anvil to rotate idle and applies an impact to the anvil in a rotational direction after rotating idle by a predetermined angle, the rotary impact tool including an impact detector configured to detect impacts and a speed switching device configured to switch the rotational speed of the motor, and when the impact detector detects an impact during rotation of the anvil in a tightening direction, the speed switching device switches the rotational speed of the motor from a normal speed to a low speed.

Rotary impact tool

In a speed change device of an electrical power tool, a reset arm is provided separately from a switch lever, which arm is operated by a reset motor. Due to tilting motion of the reset arm, a lock ring can be returned to an unlocking position in which a second stage internal gear can be rotated, so that the speed change device can be rest to a high speed low torque mode.
