Board having twelve terminals for the connection of an asynchronous three-phase electrical motor with six windings, and motor comprising such a board

摘要

The three primary terminals (1, 5, 9) are placed at the three vertices of a triangle, and the four primary, quaternary, secondary and tertiary (1, 4, 2, 3; 5, 8, 6, 7; 9, 12, 10, 11) terminals of each group are placed in this order. These terminals thus form, with the primary terminal (9, 1, 5) of the previous group, the successive vertices of non-intersecting respective pentagons (1, 4, 2, 3, 9; 5, 8, 6, 7, 1; 9, 12, 10, 11, 5) outside the triangle and outside each of the other two pentagons. Use especially for making the various modes of connection of the windings of the motor to terminal strips. IMAGE
