  • Motor Torque and HP vs Current Mike Holt s Forum

    Oct 26 2009  At rated voltage the motor will draw rated current and deliver 2300 HP Since your measured current is less HP or KW kW=0.746 x HP the load is drawing less horsepower and exerting less torque on the shaft The motor is spinning at some speed faster than 1140 rpm or in other words the slip is less Zero slip = 1200 rpm.
