SMD Technology Kit
Today’s electronic gadgets & equipments are miniaturized with each passing day. In the industry it has largely replaced the previous construction method of fitting components with wire leads into holes in the circuit board (also called through-hole technology) and it has totally revolutionized the manufacturing process. Surface Mount Technology (SMT) is method for constructing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). Electronics devices so made are called Surface Mount Devices or MSDs. An SMD component is usually smaller then its leaded counterpart because it has no leads or smaller leads. It may have short pins or leads of various styles, flat contacts, a matrix of balls (BGAs), or terminations on the body of the component (passives), unlike discrete components, SMD components have a huge vareity of packages (size). SMD Technology will be the order of the day for the electronics industry in the coming years.

The product helps to get fully acquainted with the basic concepts and functioning of the tests conducted on a single phase transformers. The product is represented in such an easy way so that each test can be studied in proper sequence. The varied scope of learning makes the subject complete understanding and interesting.

3 Phase Wound Rotor Slipring Motor

3 Phase Wound Rotor Slipring Motor

Slipring motor belongs to the family of 3Phase Induction motors, with the difference that the rotor is not same as Induction motors instead has windings with slipring & slipring holder on the rotor. These motors find major application in Crane applications & had the advantage over induction motors that by inserting resistance in the rotor winding the speed can be varied, though this advantage is not valid today as Induction motors have go VVVF drives for speed control. This Model is the Industrial/Educational model suitable for demonstrating to students the complete know of the Basics, Components, Starting methods, Speed-Torque behavior, 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, Effect of resistance in rotor, Effects of Single phasing, Effect of voltage imbalance operation, Blocked rotor test.

Split Phase AC Motor

Split Phase AC Motor

These motors belong to the Single phase motor family, but these do not have capacitors to provide the initial turning effect, and hence have a very low starting torque. This Model is the Industrial/Educational model suitable for demonstrating to students the complete know of the Basics, Starting method, Winding study, Study of Speed-Torque, Study of Efficiency & Maintenance of these motors packaged in small rating.Students can make connections of their own with the help of the terminations provided.
