Apparatus (1) and method for winding coils (B) of a wire conductor (W) around respective radial poles (10c) of a core (10) of a dynamo electric machine component. The apparatus (1) comprises a wire dispenser arm (11) which rotates about a radial pole (10c) at a time to dispense the wire conductor (W) forming the turns (S). A first wire guide (32) is, furthermore, provided positioned at a first axial end (A) from the radial pole (10c) being wound and moved along a moving direction (132a, 132b) parallel to the radial direction (110c) of the radial pole (10c) to form a respective coil (B). A second and a third wire guide (36, 37) are, furthermore, provided positioned respectively, in a first and in a second slot (10a, 10b) adjacent to the radial pole (10c) being wound at opposite sides. The second and the third wire guides (36, 37) are positioned with respect to the first wire guide (32) in such a way to form at least a respective passageway (38a, 38b, 38′a, 38′b) for the wire conductor W. The apparatus (1) comprises, furthermore, at least a first and a second guide portion (35a, 35b, 35′a, 35′b) coplanar to each other in order to close, at least partially, the, or each, passageway (38a, 38b, 38′a, 38′b) during winding of the radial pole (10c).
Apparatus (1) for winding a plurality of coils (B) of a wire conductor (W) around respective radial poles (10c) of a core (10) of a dynamo electric machine component arranged according to respective radial directions (110c), said coils (B) being formed by a plurality of turns of a wire conductor (S) each of which formed of two opposite longitudinal stretches, wherein each longitudinal stretch is arranged to be deposited in a respective slot (10a,10b), and two stretches of a turn of a wire conductor are each deposited adjacent to a respective first axial end (A) of said radial pole (10c), said apparatus (1) comprising:
Apparatus according to any one of the previous claims, wherein first guide portions (35a, 35b) are provided protruding, respectively, from said second wire guide (36) and from said third wire guide (37) and arranged to close, at least partially, a respective first passageway (38a, 38b) defined between said first wire guide (32) and said second wire guide (36), and between said first wire guide (32) and said third wire guide (37) at opposite sides (L, L′) of said radial pole (10c) being wound.
Apparatus according to any claim from 1 to 4, wherein at least a first guide portion (35a, 35b) is provided protruding from at least one between said second wire guide (36) and said third wire guide (37) and arranged to close, at least partially, a respective first passageway (38a, 38b) defined between said first wire guide (32) and said second wire guide (36), or between said first wire guide (32) and said third wire guide (37), wherein a fourth wire guide (32′) is, furthermore, provided arranged to be selectively positioned at a second axial end (A′) of said radial pole (10c) being wound that is opposite to said first end (A), and arranged to be moved, during winding, along said moving direction (132a, 132b) parallel to the radial direction of said radial pole (10c) to form a respective coil (B), and wherein at least a second guide portion (35′a, 35′b) is provided protruding from at least one between said second wire guide (36) and said third wire guide (37) and arranged to close, at least partially, a second passageway (38′a, 38′b) defined between said fourth wire guide (32′) and said second wire guide (36), or between said fourth wire guide (32′) and said third wire guide (37).
Method for winding a plurality of coils (B) of a wire conductor (W) around respective radial poles (10c) of a core (10) of a dynamo electric machine component arranged according to respective radial directions (110c), said coils (B) being formed by a plurality of turns of a wire conductor (S) each of which formed of two opposite longitudinal stretches, wherein each longitudinal stretch of a turn of a wire conductor is positioned in a respective slot (10a,10b), and two stretches of a turn of a wire conductor are each deposited adjacent to a respective axial end (A) of the radial pole (10c);
Method according to any claim from 7 to 9, wherein a step is furthermore provided for closing, at least partially, first passageways (38a, 38b) defined at opposite sides (L, L′) of said pole (10c) being wound, respectively, between said first wire guide (32) and said second wire guide (36), and between said first wire guide (32) and said third wire guide (37), by first guide portions (35a, 35b), respectively, protruding from said second wire guide (36) and from said third wire guide (37).
Method according to any claim from 7 to 10, wherein a step is, furthermore, provided for selectively positioning a fourth wire guide (32′) at a second axial end (A′) opposite to said first axial end (A) of said radial pole (10c) being wound and for moving said fourth wire guide (32′) along said radial direction (110c) of said radial pole (10c) being wound, and wherein the steps are, furthermore, of:
