- electricpy.fault.indmachphs3torq(t, Is0, Lr, Ls, Lm, Rr, Rs, wrf=0, freq=60)[source]¶
Induction Machine 3-Phase Torque Calculator.
Determines the torque exerted during a three-phase fault on an induction machine.
- Parameters:
t (array_like) – The time at which to find the current, may be int, float, or numpy array.
Is0 (complex) – The initial (t=0) current on the stator.
Lr (float) – Inductance of the Rotor (in Henrys).
Ls (float) – Inductance of the Stator (in Henrys).
Lm (float) – Inductance of the Magnetizing branch (in Henrys).
Rr (float) – Resistance of the Rotor (in Ohms).
Rs (float) – Resistance of the Stator (in Ohms).
p (int) – Number of electrical poles.
wrf (float, optional) – Frequency (in radians/sec) of the rotor slip. default=0
freq (float, optional) – Base frequency of the system (in Hertz). default=60
- Returns:
Tem – Induction machine torque in N*m
- Return type:
array_like
