A hand-held power tool is provided that includes a housing assembly, an output spindle, and a motor endbell. The housing assembly supports an electric motor having a rotor configured to rotate when the electric motor is supplied with power. The output spindle protrudes from an output end of the housing assembly, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The motor endbell is located on the housing assembly adjacent the electric motor and opposite the output spindle. An illustrative controller is operable to determine phases of a fastening operation in which the hand-held power tool is operating. The phases of the fastening operation of the hand-held power tool include two phases including: (1) a continuous run phase and (2) an impacting phase.

A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a motor configured to perform at least one of rotation of the bit holding portion and movement of the bit holding portion along the axial direction; and a control unit configured to control a position of the bit holding portion along the axial direction by a rotation amount of the motor. The control unit is configured to stop rotation of the motor based on a load applied to the motor rotated in one direction of moving the bit holding portion in a direction approaching a fastening target.

A power tool communication system including an external device including a first controller configured to transmit, via wireless communication to a power tool, configuration data including a work light duration parameter value and a work light brightness parameter value. The power tool includes a housing, a brushless direct current (DC) motor, a trigger, a work light, a wireless communication circuit configured to wirelessly communicate with the external device to receive the configuration data, and a second controller configured to control a work light duration of the work light based on the work light duration parameter value, and control a work light brightness of the work light based on the work light brightness parameter value.

The electric screwdriver apparatus control method is executed by an electric screwdriver apparatus. A processing module of the electric screwdriver apparatus loads a configuration data, and the processing module controls a motor module to accelerate a rotational speed to a target rotational speed. When a revolution number exceeds a first revolution number, the processing module controls the motor module to decelerate to a first rotational speed. When a torque value exceeds a first torque value, the processing module determines whether a fastening process of a screw ends with a hard stop or a soft stop according to the configuration data. If the fastening process ends with the hard stop, then the screw is additionally tightened for a hard stop angle, vice versa. The processing module tightens the screw according to the configuration data, the torque value and a rotational speed value, improving the process of fastening the screw.

A portable torque power tool is disclosed herein and includes: a motor to generate a turning force; a drive to transfer the turning force; a turning force multiplication mechanism assembly to multiply the turning force; a shifter assembly to shift the tool between a lower speed/higher torque (LSHT) mode and a higher speed/lower torque (HSLT) mode; a torque transducer to measure torque output; wherein torque output is controlled by the torque transducer in LSHT mode; and wherein torque output is controlled by motor current in HSLT mode. In one embodiment of the present application, the torque transducer is a wireless torque transducer assembly formed at or near an output of a housing of the turning force multiplication assembly to improve measurement accuracy of torque output.

An electric work machine includes: a motor; a first planetary gear mechanism; a second planetary gear mechanism; a spindle; a first speed switch mechanism including a first internal gear of a first stage unit and a second internal gear of a second stage unit; and a second speed switch mechanism. The first speed switch mechanism performs switching between a first speed reducing mode in which rotation of the second internal gear is prevented and rotation of the first internal gear is allowed and a second speed reducing mode in which rotation of the first internal gear is prevented and rotation of the second internal gear is allowed. The second speed switch mechanism performs switching between an enabled mode in which rotation of an internal gear of the second planetary gear mechanism is prevented and a disabled mode in which the rotation of the internal gear is allowed.

A driver-drill (1) includes: a controller (32), which stops rotation of a brushless motor (9) when a torque applied to a spindle (26) reaches a prescribed clutch-actuation torque; and a dial (65), which is capable of specifying, to the controller (32), the setting of the prescribed clutch-actuation torque within a prescribed high-low range of values. In the controller (32), a relationship between clutch-actuation torques and each value in the high-low range is set such that, in a first range in which the values are low, changes in the clutch-actuation torques are the same in the low-speed mode and in the high-speed mode and such that, in a second range outside of the first range, the clutch-actuation torques in the low-speed mode are higher than in the high-speed mode.

It is an object of the invention to provide a technique for enhancing the operability of a power tool. A representative screwdriver 100 is provided which has a motor 110 and a driving mechanism 120. The driving mechanism 120 has a rotation transmitting mechanism including a driving cam 137 and a driven cam 157, and a cam engagement state is switched by movement of the spindle 150 in a longitudinal direction of the spindle. The position of the spindle 150 in the longitudinal direction is detected by a detecting mechanism 162 that is disposed on the opposite side of the rotation transmitting mechanism from a front end region in the longitudinal direction of the spindle 150. A controller 180 controls the rotation speed of the motor 110 based on the detection result of the detecting mechanism 162 and drives the motor 110.

An electric working machine in one aspect of the present disclosure includes a motor, a controller, and a setter. The controller is configured to change a rotational state of the motor, in response to an establishment of a condition for change after the motor is initiated, from a low speed rotation to a high speed rotation. The setter is configured to set, based on a situation in the motor in the low speed rotation, a control variable of the motor in the high speed rotation and/or the condition for change.
