Magnetic motor - Import export

The EVO propeller stirrer is the natural evolution of the classic standard stirrer by Caseartecnica Bartoli. Equipped with brushless motor with permanent magnets without reducer and no oil inside, it prevents product contamination and reduces the environmental impact. In addition to being built entirely in stainless steel and materials compatible with food contact, it guarantees energy savings. Other important features are the degree of protection IP65, reduced dimensions and reduced maintenance. The agitator is designed for quick tool change according to the various processing stages: heating and cooking, pinning with the cutting of the curd, final cleaning of the double bottoms.

Politubes, in conjunction with DuPont, has developed a special spiral-wound tube made of heat-shrinkable polyester (Mylar HS), which enables automated fixing of permanent magnets, thereby reducing the cost of assembling these motors.Important advantages are: 1.Unlike very expensive steel rings, the spiral-wound tube also wraps around and protects the ends of the magnets, which are also subject to corrosion. 2.The trimming that often has to be done during the assembly process when using rigid rings is avoided; the Politubes spiral-wound tube adheres perfectly to the magnets, taking their shape and protecting them from cracking and scratching; this also guarantees perfect balancing of the rotor. 3.Part of the assembly process is removed, since potentially costly and often manual bandage with tape impregnated with epoxy resins can be eliminated; this avoids as well lenghty resin activation time in oven; productivity is thereby increased and hidden production costs reduced.

Politubes is specialized in the manufacturing of insulating tubes and end caps strictly customized for electromechanical and automotive world & performance release liners for tire producers. Our insulating tubes and caps are widely used in the manufacture of electric motors, cable harness, motor lead termination, compressors and transformers as well as in transistors, capacitors, heating element and batteries. They are also used to fix and protect permanent magnets for BLDC brushless motors. Our performance films with a high technological content guarantee particular mechanical resistance and release qualities and they are used as release liners for the tire production by the world leader producers. We holds main quality certifications as UL TEOU 2-8 nr E350605 and the most recent ISO 9001:2015 certifications. Politubes manufactures in-house in a modern 4.000 sqm plant in Italy few km far from Milano

Politubes offers a unique spiral wound continuous polyester heat shrink sleeve. This sleeve is supplied in rolls of several hundred meters. Its aim is: •Reduce noise by various decibel in universal motors •Protect rotor magnets against dust extending its life •Compact rotor surface where there are grooves fixing rotor balancing This hi-tech tube is produced with a spiral wound technology without any overlapping of layers; it offers: •a perfect roundness of the tubes that is the only way to guarantee the rotor balancing ; on the other hand overlaps of layers will cause the rotor unbalancing where is the overlap of layers that of course may cause many problems to the motors •to avoid breaks and ruptures in the overlapping areas after the heat shrink process It is supplied with very low thicknesses thickness ranging between 50 and 75 micron, wound on rolls of several hundred metres long to reduce transport costs.
