  • Apparatus and method for determining mechanical parameters of an electric motor and load
    Patent number: 11682993
    Abstract: A method, system, and apparatus are provided for determining mechanical characteristics of an electric motor and mechanical load with a speed signal modulator, FOC current loop, sensor-less rotor speed estimator, and speed signal demodulator which are configured to provide a q-axis AC reference current, q-axis DC reference current, estimated maximum AC rotor speed, estimated DC rotor speed, estimated phase angle of the AC rotor speed component, and torque constant to a mechanical characteristics estimator which is configured to determine a plurality of load torque parameters for the electric motor and mechanical load which include a combined moment of inertia parameter, a combined static friction, and a combined viscous friction coefficient parameter.
