Stepper Motor-IRTF

Category: Toolbox > eDrives > Motors


      U_s: Input voltage vector for motor in alpha-beta convention. 

      T_l: Load torque.

      lock_on: Clamp enable for motor shaft. When input is set to 1, the shaft speed is forced to zero. (binary input)


      psi_R: Rotor flux vectors in d-q axes convention.

      i_s: Output current vector for stator currents in alpha-beta convention.

      T_me: Mechanical torque generated by the motor.

      theta_me: Mechanical angular position of the rotor.

      w_me: Mechanical angular speed of the rotor.

Description: The Stepper Motor-IRTF block is a motor model for simulation of stepper motors. This is a mathematical model of an electrical machine based on Ideal Rotating Transformer model.
