Title:
METHOD AND DEVICE FOR MOUNTING COIL IN STATOR OF MOTOR
Document Type and Number:
Japanese Patent JPS60210154
Kind Code:
A
Abstract:
A working process for the winding of stators (1) of electric motors, in which the coils (12) are inserted between two spreadable elastic tongues (4a and 4b) of draw-in needles and are introduced into the stator grooves (2) in this way and the coils (12) are interconnected according to the polarity before being drawn-in, is improved in terms of its applicability to small and very small-size motors and of greater economy. The process steps are: fixing the stator (1) provided with groove insulations in a vertical axial position, laying the needle tongues (4a, 4b) against one another in pairs and inserting them into a draw-in tool with correct polarity, introducing them centrally into the stator (1) up to a predetermined groove length, positive connection of the tool to a draw-in spindle (9), placing elastic caps over every two adjacent needle tongues, threading the coil strands in between the spread needle tongues, placing a guide ring over the inserted coil heads, introducing a fixing star (19) between the needle rings as a draw-in guide, and pulling the tool through downwards until the top ends of the draw-in needles are flush with the top edge of the stator. The draw-in tool serving for carrying out the process as well as the improved draw-in needles and the auxiliary devices are described.
