Three Phase AC Source


Category: Sources

The Three Phase AC Source block provides a 3-phase signal that can be used as either a current or voltage source for driving asynchronous motors. As outputs, phase a leads phase b, and phase b leads phase c. All phases are separated 120o.

Frequency: Represents the signal frequency in hertz.

Amplitude: Represents the signal amplitude (arbitrary units).

Driven by a 155 VRMS, 60 Hz 3 phase source (220 V peak amplitude), the 3-phase AC induction motor rotor angular velocity without load connected is driven to 371 rad/sec steady state.

Field rate is 2*π*60= 377 rad/sec. The slip is calculated by:
