BHARATH ELECTRIC MOTORS

Lakshmi Nagar, Coimbatore, Tamil Nadu

DC Machines have been the running horse for the Industry since, Shunt motors have been the most used due to their very simple speed control, Ruggedness & High Torque capabilities.This Mode! is the Industrial/Educational model suitable for demonstrating to students the complete know of the Basics, Components, Starting methods, Wear & Tear & Maintenance of these motors packaged in small rating.

Students can make connections of their own with the help of the terminations provided for study of features viz Starting methods, Speed control, Speed-Torque, Effects of Field voltage, Effects of Armature voltage, Motor/Generator operation.
