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
