DC Series Machines

Model HV-EXP2258
DC Machineshave been the running horse for the Industry since 100Years, Where ever Heavy Torque is required Series motors are theoption, these motors need load to start, these motors have the tractiveeffect & are even named as Traction motors, applications likerailways, material handling machines use such motors. This Model is the Industrial/Educational model suitable for demonstrating to tudents the complete know of the Basics, Components, Starting methods, Wear & Tear & maintenance of these motors packaged in small rating.Students can make connnections of their own with the help of the terminations provided for study of features viz starting methods,Speed control, Speed-Torque, Effects of Armature voltage,Behaviour with Load, Motor/Generator operation. Technical Specs : Power ratings available :350W /750W /1KW /2 KW /3KW/ 5KW Voltage Input: 220V DC Armature :220V DC RPM: 1500 /3000 RPM Single /Double shaft extension,Solid yoke List Of Experiments Behavior of Resistance Cut off method of starting Behavior of Voltage control method of starting Speed Control Load test & No load test of machine Speed-Torque Analysis Voltage-Speed Analysis Efficiency Analysis Analysis of Commutation Cold Resistance & Hot Resistance Motor Operation parameters Generator Operation parameters Basic Overhauling Know how.
