Stepper Motor-IRTF

Category: Toolbox > eDrives > Motors

Inputs:

•      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)

Outputs:

•      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 the Ideal Rotating Transformer model.

Magnet Flux (Wb): Indicates the estimated magnet flux.

Number of Poles Pairs: Indicates the number of motor pole pairs.

Rotational Inertia: Indicates an approximation of inertial load on rotor shaft.

Stator Inductance (H): Indicates the measured stator inductance of the motor.

Stator Resistance (ohms): Indicates the measured stator resistance of the motor.
