Claim 0:
1. A method of calculating a correction factor for an electric motor, the method comprising:
obtaining at least one electric motor parameter of the electric motor;
calculating the correction factor for the electric motor of a heating, ventilating, and air conditioning (HVAC) system based on the at least one electric motor parameter, wherein the calculating the correction factor consists of:
determining an amount of torque loss acting against the electric motor;
determining a saturation starting point torque level of the electric motor;
determining a saturation torque slope of the electric motor;
determining a torque scaling factor of the electric motor; and

programming a motor controller associated with the electric motor with the correction factor.
