摘要： A motor-driven integrated circuit comprises a plurality of position comparators, a timer and a central processing. Each of the plurality of position comparators receives a pole detection signal denoted a position of a rotor of a motor. The timer receives a timing interrupt signal output by the plurality of position comparators when a predetermined edge of the pole detection signal is generated and records a time of the predetermined edge. The central processing unit obtains a rotation speed of the motor according to a time difference between two predetermined edges.

摘要： A system comprising a gear having at least one slot, wherein the gear is connected to an icetray and a motor so that when the motor rotates the gear, the icetray twists, and an optical sensor that detects when the gear has rotated the slot over the optical sensor. The icetray twists while the gear is rotated in a first direction away from a home position to a reverse twist position. The rotation of gear then reverses to twist the icetray to a harvest position in a second direction that is opposite of the first direction until ice in the icetray is dislodged.

摘要： An electric tool includes: a motor configured to be driven by PWM controlling a semiconductor switching element; a trigger configured to adjust startup and rotation of the motor; a changeover switch configured to switch a rotation direction of the motor between a forward rotation and a reverse rotation; a power transmission mechanism configured to rotate a tip tool by the motor, and a controller configured to control rotation of the motor. When the reverse rotation is set by the changeover switch, the controller PWM controls the semiconductor switching element at a high duty ratio after the trigger is pulled to drive the motor, and thereafter drives the motor at a state where the high duty ratio is changed to a low duty ratio.
