Product Code : SCL-EELE-12949
Indian Lab Suppliers supplies the Three Phase Synchronous Motor Lab (Product ID: 12949) as part of its electronics engineering lab equipment range. It is a motor-generator set with a control panel for plotting the V and inverted V curves of a three-phase synchronous motor.
Quick Answer
A 1 HP, 415 V, 1500 rpm salient-pole synchronous motor with 220 V DC excitation drives a 0.6 kW, 200 V DC shunt machine that acts as a loading generator; both are flexibly coupled on a mild steel channel base. Keeping the load fixed and varying the field current, students plot armature current against field current (the V curve) and power factor against field current (the inverted V curve), and see the power factor pass from lagging (under-excited) through unity to capacitive (over-excited). Two digital wattmeters (250 V, 5 A each) give the input power, and a digital tachometer checks the speed.
