Sander Having a Brushless Motor

Abstract

A sander may include a wand having a proximal end and a distal end, a sanding head mounted to the proximal end of the wand, and a brushless motor mounted on the distal end of the wand that is configured to provide rotational motion to the sanding head.

1 . A sander comprising:
 a wand having a proximal end and a distal end;   a sanding head mounted to the proximal end of the wand; and   a brushless motor mounted on the distal end of the wand that is configured to provide rotational motion to the sanding head.   
     
     
         2 . The sander of  claim 1  wherein the brushless motor is a direct current (DC) brushless motor. 
     
     
         3 . The sander of  claim 1  wherein the brushless motor is an alternating current (AC) brushless motor. 
     
     
         4 . The sander of  claim 1  wherein the sanding head is mounted by a pivotal joint to the proximal end of the wand. 
     
     
         5 . The sander of  claim 1  further comprising a drive shaft extending a length of the wand that is coupled to the sanding head and the brushless motor. 
     
     
         6 . The sander of  claim 1  further comprising a motor housing enclosing one or more components of the brushless motor. 
     
     
         7 . The sander of  claim 6  further comprising a fan mounted external to the motor housing. 
     
     
         8 . The sander of  claim 6  further comprising a sander housing having at least one vent and substantially enclosing the motor housing.
