Abstract

An electric machine includes a housing, a mount within the housing, and power and control electronics coupled to the mount. An interference fit is formed between the mount and the housing that secures the mount within the housing independent of mechanical fasteners. The electric machine can also include a segmented or non-segmented stator within the housing.

Claims

exact text as granted — not AI-modified
1 - 9 . (canceled)  
   
   
       10 . An electric machine comprising a housing, a mount within the housing, and power and control electronics coupled to the mount, the mount and the housing forming an interference fit therebetween, the interference fit securing the mount within the housing independent of mechanical fasteners.  
   
   
       11 . The machine of  claim 10 , wherein the mount abuts against an internal stop defined within the housing.  
   
   
       12 . The machine of  claim 10 , wherein the mount has a coefficient of thermal expansion about equal to or greater than the housing's coefficient of thermal expansion.  
   
   
       13 . The machine of  claim 10 , wherein the mount and the housing have coefficients of thermal expansion such that the interference fit is maintained across an operating temperature range of the machine.  
   
   
       14 . The machine of  claim 10 , wherein the mount operates as a heat sink for one or more of the electronics coupled thereto.  
   
   
       15 . The machine of  claim 10 , wherein the housing includes one or more external fins for increased heat dissipation from the housing.  
   
   
       16 . The machine of  claim 10 , wherein the interference fit between the housing and the mount maintains good thermal conductivity between the housing and the mount.  
   
   
       17 . The machine of  claim 10 , further comprising a stator within the housing.  
   
   
       18 . An electric supercharger comprising the machine of  claim 10 .  
   
   
       19 . A vehicle comprising the electric supercharger of  claim 18 .  
   
   
       20 . An electric supercharger comprising a housing, a stator within the housing, and power and control electronics integrated within the housing.  
   
   
       21 . A vehicle comprising the electric supercharger of  claim 20.
