DC Motor Coupled 3ph. AC Motor Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-EELE-13001

Indian Lab Suppliers supplies the DC Motor Coupled 3ph. AC Motor Trainer (Product ID: 13001) as part of its electronics engineering lab equipment range. It is a 300 W machines trainer in which a trunnion-mounted DC machine is coupled to a three-phase integrated AC machine for 15 DC and AC machine experiments.

Quick Answer

Both machines work at up to 300 W and 1500 rpm, sit on a painted base frame with gear couplings that need no screws, and can be exchanged easily. The DC integrated machine is trunnion mounted, so it acts as a dynamometer: it measures shaft torque and speed electronically and can load a motor or drive a generator, which a powder or eddy-current brake cannot do. The DC machine is connected as shunt, series, separately excited or compound to plot motor speed-torque curves and generator V-I and efficiency curves, plus the open circuit characteristic. The three-phase machine is run as a wound-rotor induction motor (rotor shorted or with added rotor resistance), with DOL, star-delta and rotor resistance starters, as a synchronous motor for V curves and power factor improvement, and as a synchronous generator for V-I curves.

Where This Is Used

Used in electrical machines laboratories where one compact bench replaces several full-size motor-generator sets. The shafts turn at up to 1500 rpm on mains-fed panels, so keep coupling guards fitted and change connections only with the supply off. Variants: DC Motor Coupled 3ph.
