Abstract

The invention discloses a pay-off stand for a motor compensating winding, relating to the industry of motor production, in particular to a special tool for producing a motor stator compensating winding. The pay-off stand mainly solves the problems that existing multi-row wheel squeezing-pulling type pay-off stands cause damage and intersected deformation of the external insulation of an electromagnetic wire, affect subsequent coil formation and occupy a large area. The rotating shaft of the pay-off stand is connected on a support frame by a bearing, an electromagnetic wire coiling wheel is clamped and fixed on the rotating shaft by a wire support plate and a wire pressing plate, and a brake device of the rotating shaft is connected on the rotating shaft. The pay-off stand cannot damage the electromagnetic wire during the coiling of the compensating winding, can ensure the insulating property of coils of the motor compensating winding and improves the motor quality. The pay-off stand is also applicable to the winding of other types of motor stator coils.

Description

technical field [0001] The invention relates to a motor manufacturing industry, in particular to a special tool for manufacturing motor stator compensation windings. Background technique [0002] At present, when the known winding of the stator compensation winding of the traction motor of a railway locomotive is made, the form of the pay-off frame is mainly a multi-row wheel extrusion type, and its main disadvantages are: ①The electromagnetic wire must pass through multiple rows of wheels Extrusion can easily cause insulation damage to the outsourcing of the electromagnetic wire; ② During winding, the electromagnetic wire is squeezed by multiple rows of wheels and undergoes multiple alternating deformations, which causes the flat copper wire in the electromagnetic wire to undergo cold work hardening, which affects the forming of the subsequent coil; ③The pay-off frame occupies a large area. Contents of the invention [0003] The object of the present invention is to over...
