DL 10280 – SET OF COMPONENTS
It includes the following components:
1. Base plate
2. Supports with bearing
3. Coupling joints
4. Flexible coupling
5. Electronic speed transducer
6. Assembling screws
7. Wrenches
8. DC stator
9. AC stator
10. Rotor with commutator
11. Brush holder with 2 brushes
12. Cage rotor
13. Ring rotor
14. Brush holder with 6 brushes
Besides, a magnetic probe is foreseen to display the magnetic fields and a transparent covering, for safety reasons, prevents students from the accidental contact with the rotating parts.
The AC STATOR is composed of a metal frame supporting the laminated magnetic circuit, because interested by a flux variable in time, and the electrical winding.
The sheet iron pack is 60 mm long, with internal diameter of 80 mm and external one of 150 mm and it presents 24 half-closed slots inside of which there is a double three-phase winding: the beginnings and the ends of the different phases are shown outside the stator on a suitable educational terminal board.
The winding is a double layer one of the long coil lap type, with winding span 6 (1÷7).
Every slot contains two coils of 19 turns each of enameled wire of diameter 1.12 mm.
AUTOMATIC CONFIGURATION
THIS SYSTEM IS A COMPLETE SET OF COMPONENTS AND MODULES SUITABLE FOR ASSEMBLING THE ROTATING ELECTRIC MACHINES, BOTH FOR DIRECT CURRENT AND FOR ALTERNATING CURRENT.
STUDENTS CAN PERFORM A CRITICAL AND WELL ANALYZED ASSEMBLY, IN ORDER TO UNDERSTAND THE PRODUCTION TECHNIQUES BEFORE PERFORMING PRACTICAL TESTS OF THE OPERATING CHARACTERISTICS. THE SYSTEM IS SUPPLIED AT LOW VOLTAGES IN ORDER TO PREVENT THE RISK OF ACCIDENTS. HOWEVER, THE MACHINES HAVE FULLY INDUSTRIAL FEATURES.
