Outer rotor type motor of washing machine

Abstract

Disclosed is an outer rotor type motor of a washing machine, in which a rotor is more simply installed. The present invention includes a stator having an outer circumference on which a coil is wound, a rotor provided to leave a predetermined interval from an outside of the stator, the rotor rotating when a current is applied to the coil, and a frame having a fixing means for fixing the rotor wherein the fixing means is built in one body of an inner circumference of the frame.

What is claimed is:  
     
         1 . An outer rotor type motor comprising: 
 a stator having an outer circumference on which a coil is wound;    a rotor provided to leave a predetermined interval from an outside of the stator, the rotor rotating when a current is applied to the coil; and    a frame having a fixing means for fixing the rotor wherein the fixing means is built in one body of an inner circumference of the frame.    
     
     
         2 . The outer rotor type motor as claimed in  claim 1 , wherein a tip of the frame is bent inward to form the fixing means as a fixing part to clamp a topside of the rotor.  
     
     
         3 . The outer rotor type motor as claimed in  claim 2 , wherein the fixing part is bent to have a ‘channel’ shape.  
     
     
         4 . The outer rotor type motor as claimed in  claim 2 , wherein a guide groove is formed on the topside of the rotor brought contact with the fixing part.  
     
     
         5 . The outer rotor type motor as claimed in  claim 1 , wherein the frame is made of a metal-based material.  
     
     
         6 . A washing machine comprising: 
 an outer tub holding water;    an inner tub in the outer tub to hold a laundry;    an outer rotor type motor comprising: 
 a stator having an outer circumference on which a coil is wound;  
 a rotor provided to leave a predetermined interval from an outside of the stator, the rotor rotating when a current is applied to the coil; and  
 a frame having a fixing means for fixing the rotor wherein the fixing means is built in one body of an inner circumference of the frame; and  
   a shaft connecting the motor to the inner tub.    
     
     
         7 . The washing machine as claimed in  claim 6 , wherein a tip of the frame is bent inward to form the fixing means as a fixing part to clamp a topside of the rotor.  
     
     
         8 . The washing machine as claimed in  claim 7 , wherein the fixing part is bent to have a ‘channel’ shape.  
     
     
         9 . The washing machine as claimed in  claim 7 , wherein a guide groove is formed on the topside of the rotor brought contact with the fixing part.  
     
     
         10 . The washing machine as claimed in  claim 6 , wherein the frame is made of a metal-based material.
