Indian Lab Suppliers supplies the 0.5 KVA / 415 V / Rotor wound / Star connected / 220 V DC stator excited / Separately excited / Manually regulated / 1500 RPM / Salient Pole type / 3 Phase / UPF / Synchronous Alternator . Frame : 100 (Product ID: 13069) as part of its electronics engineering lab equipment range. It is a 0.5 kVA, 415 V three-phase salient-pole synchronous alternator in a 100 frame, used for generation, excitation and regulation tests in a machines laboratory.
Quick Answer
The machine delivers 0.5 kVA at 415 V, three phase, from a star-connected winding, and is rated for unity power factor (UPF). The field is separately excited from 220 V DC and regulated by hand, so students can see how the generated voltage follows field current. At 1500 rpm a four-pole machine generates 50 Hz. The rotor winding is brought out through slip rings, and a damper winding on the rotor lets the same machine start like an induction motor when it is run as a synchronous motor. Please confirm the excitation voltage at quotation, as 110 V DC is also quoted for this machine family.

Where This Is Used
Used in electrical machines labs for open-circuit, short-circuit and load regulation work when driven at 1500 rpm by a prime mover; a three-phase resistive load such as 3 Phase / 5 A / 415 V / Complete with mains switch and caster wheels for easy movement. (Product ID: 13100) can take its output. For a larger machine of the same type see 1 KVA / 415 V / Rotor wound / Star connected Synchronous Alternator . Frame : 100 (Product ID: 13070). Work on 415 V three-phase supply and rotating shafts must be done under qualified supervision, with the frame earthed and couplings covered.

Frequently Asked Questions
What frequency does it generate?
50 Hz when driven at its rated 1500 rpm.
How is the output voltage adjusted?
By changing the DC field current by hand; speed also affects it.
What does UPF in the rating mean?
The 0.5 kVA rating is at unity power factor.
