  Electric motor output power is given as P em = T ω = F v {\displaystyle P_{\text{em}}=T\omega =Fv} where:
  
  In Imperial units a motor's mechanical power output is given by,
  
  where:
  
  In an asynchronous or induction motor, the relationship between motor speed and air gap power is given by the following:
