**Motors

**Inputs:**

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

•**T_l: **Load torque.

•**Rotor_lock: **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 coordinates.

•**i_s: **Output current vector for stator currents in alpha-beta
coordinates.

•**T_me: **Mechanical shaft torque of the motor.

•**w_me: **Mechanical shaft speed of the rotor.

**Description: **The Induction Motor-IRTF block is a
motor model for a three phase AC Induction machine. This is a mathematical model
of an electrical machine based on the Ideal Rotating Transformer model. A four
parameter model representation, as shown below, is used.** **

**Leakage Inductance (H):** Indicates the combined
(stator/rotor) stator referred leakage inductance.

**Magnetizing Inductance (H):** Indicates the stator
referred magnetizing inductance .

**Number of Pole Pairs:** Indicates the number of motor
pole pairs.

**Rotational Inertia:** Indicates the inertia of the
rotor (plus mechanical load if attached).

**Rotor Resistance (ohms):** Indicates the stator
referred rotor resistance .

**Stator Resistance (ohms):** Indicates the stator
winding resistance .

**Slip (shown in the equivalent model above):** Defined as where represent the synchronous and
mechanical shaft speed, respectively.
