HOLLOW SHAFT MOTORS

Generic Features:

Asynchronous single phase electric motors totally enclosed with external fan-cooling. Insulation class F tropicalized.

Constructive shapes: IM B3, IM B5, IM B14, IM B34, IM B35. Manufactured with the best products present on the Italian market to obtain the best output and lifetime.

Mechanical construction and assembling in automatic lines to reduce to the minimum noise and vibrations. Test of the finished product on 100% of the production to eliminate the returns caused by manufacturing defects and have the best reliability. Shafts are generally made of carbon steel C45 but on request we can also make shafts in stainless steel.

The housings, shields and flanges are in die-casted aluminium alloy (on request also in cast iron), fan and fan cover in thermoplastic material or zinc-coated sheet (only fan cover).

The standard voltage is Volt 230-50Hz, 5% of the rated voltage.
