Abstract

A method for torque compensation of a motor associated with a medical instrument includes determining a torque profile for a motor, the torque profile defining torque output as a function of rotor angle and during operation of the motor, compensating for deviations in the torque profile by adjusting an input signal to the motor, the compensating being based on the torque profile and rotor position.
