The first handle includes a user input configured to be actuated by a first hand of a user. The second handle includes a touch sensor configured to detect a second hand of the user on the second handle. The controller is configured to determine whether the user input is actuated, determine whether the second hand of the user is on the second handle, control, in response to both the user input being actuated and the second hand of the user being on the second handle, the motor to drive the motor, and prohibit, in response to the user input being actuated and the second hand of the user not being on the second handle, operation of the motor.

摘要： A motor having a circuit board including at least two MEMS sensors. The circuit board is mounted within a housing of the motor using the same fasteners as an encoder of the motor. Mounting the MEMS sensors to the circuit board simplifies assembly of the motor and standardizes the positioning of the MEMS sensors within the housing, while the overall motor footprint is unaffected.

摘要： A method for adjusting a drive control signal for a motor includes providing a drive circuit having a first pin and a second pin, wherein the drive circuit generates the drive signal. A period of the drive signal is determined and an advance angle count value is extracted from a storage register in accordance with the period of the drive signal. One of the advance angle count value and a first control signal coupled to the first input pin are used to determine an advance angle adjustment range or an advance angle count range and a second control signal received via the second input pin are used to determine an advance angle adjustment range. The drive control signal is adjusted in response to the advance angle adjustment range.

摘要： A power tool is disclosed having a compact AC switch assembly. An electric motor driving the power tool is contained within a housing that includes a handle. A trigger is slidingly received in the handle and moves in an axis of trigger travel along a trigger travel distance extending between an extended position of the trigger and a depressed position. A trigger switch including a printed circuit board is disposed in mechanical communication with the trigger and controls the electric motor in accordance with trigger position. The printed circuit board has a plurality of conductive traces that are sequentially arranged and linearly aligned adjacent the trigger in a direction that is transverse to the axis of trigger travel to reduce the width of the printed circuit board to a value that is less than or equal to three times the trigger travel distance.
