WINDING SYSTEMS FOR SEGMENTED MOTORS



Sipro linear multispindle winding machines have been used over many

years to produce water pumps and fan motors.

Special tools allowed also to wind some stators with external poles.

Historical References



New developments in motor design (segmented motors) have caused many changes:

Motors are smaller and have higher performances

If the windings of the motor are all separate (one per segment with 2 contacts each and no wire connecting 2 different segments) the multispindle winding technology can be easily used.

If more segments are connected by the same wire without interruptions (pole chains) flyer winding or interpolated needle winding becomes the solution.

In all cases the final motor is obtained by assembling single segments or pole chains and by connecting the wire leads.



Pole chains are wound either with the flyer winding technology

(rotating wireguide) or, if the single segments need to be very

close to each other, with interpolated needle winding

technology.

Single segments

Pole chains

Single segments are wound by rotating the coilformers with or without

laminations. This is the optimal winding technology regarding fill factor /

speed / damages to insulation.

Besides these newest developments we also offer the traditional needle

winding technology for stators with laminations obtained from one

single part.
