摘要： A hand held orbital sander, comprising:
a. a housing having an electronically commutated motor disposed therein and an orbit mechanism disposed beneath the housing;
b. a motor controller coupled to the motor;
c. a current sensor coupled to the motor controller that provides a signal indicative of motor current; and
d. the motor controller changing the speed at which it runs the motor from an idle speed to a sanding speed based upon at least one of change in motor current and change in motor speed as the sander is removed from a work piece and changing the speed at which it runs the motor from sanding speed to idle speed based upon at least one of change in motor current and change in motor speed as the sander is applied to the work piece.

摘要： A hand held orbital sander has a housing having an electronically commutated motor disposed therein and an orbit mechanism disposed beneath the housing. A motor controller is coupled to the motor. The motor controller changes the speed at which it runs the motor from an idle speed to a sanding speed upon the motor speed dropping from idle speed to an idle speed threshold value and changes the speed at which it runs the motor from sanding speed to idle speed upon the motor speed increasing from sanding speed to a sanding speed threshold value. The sander may have a mechanical brake that brakes the orbit mechanism and the motor controller also dynamically brakes the motor.
