Claim 8:
9. The method of claim 2, wherein:
in the monitoring, the coil temperature of the motor unit is determined by, T
   =
   
    
     
      (
      
       
        R
        -
        
         R
         0
        
       
       
        R
        0
       
      
      )
     
     ×
     
      (
      
       K
       +
       
        T
        0
       
      
      )
     
    
    +
    
     T
     0
