The Standard Lab has been designed for experiments and testing in Electrical Machines in education. The machines are basically industrial models, self protect kind, with coupling half joint, especially equipped to be suitable for students training in laboratory. For this purpose the winding ends are connected to 4 mm safety socket in a metal housing on top of which a clear synoptic diagram is engraved as an educational terminal board. 

The student can easily understand operation and winding connection. Also most of the accessories and instruments designed in Panel System A4 is high in standard. The machines power is approximately a maximum of 400W, as the supply requirement for the system operation requires 230/415V, 60Hz.
