Torque motors - Import export

Magnetic couplings are used as transmission mechanisms in modern pumps, which makes it possible to obtain a qualitatively new 100% tight device without making essential changes to the design of the electric drive and the wet end of the pump. At present Villina offers GNVC, GNGC and GNVC-P series vertical, horizontal and semi-submersible centrifugal pumps with magnetic couplings, designed for pumping explosive and flammable, toxic and corrosive fluids (petroleum products, alkalis, acids, alcohols, etc). PURPOSE Magnetic couplings for Villina centrifugal pumps allow for transmission of torque from the electric motor to the pump shaft using magnetic fields generated by permanent magnets instead of mechanical engagement devices. At the same time, there is no need to withdraw the shaft from the pump wet end to the drive device, therefore the wet end can be made in the form of a completely sealed system free of leaks which are typical for pumps with mechanical shaft seals.

The company serially produces high-torque synchronous brushless electric motors of the series AT Drive in a frame and frameless versions with a power from 150 W to 550 W. The design allows it to be installed in products for various purposes. Motors with an axial arrangement of magnets have following advantages: - High torque; - Small diameter; - High rate of peak torque; - Compound of stator winding is resistant to the temperature shock from -60 C till +170 C; - Frameless version; - Hollow rotor; - Tuning agility of motor characteristics within 20%; - Possibility to change winding commutation method. Warranty period: 12 months.
