Vario series

Категория: Электродвигатели

The Vario Non-Ex series has a welded steel enclosure to ensure the highest degree of variability and versatility. Flange rings at the ends of the enclosure increase the torsional stiffness and ensure a vibration-proof mechanical design. The steel version allows various bearing concepts, dimensions can be adapted and a wide range of instruments can be mounted. The surface cooling using flat ribs combined with a defined inner cooling circuit with shaft-mounted fan inside the motor ensure optimum motor utilization. The copper bar rotors used as standard allow starting and operating parameters to be optimized for each and every application.

Features

• Corrosion protection using special paint finishes according to the manufacturer's standard or customer's specifications.
• The motors are available as special version for polar regions down to -40 °C (without pre-heating of the motor) or desert regions up to +60 °C.
• When required, vertical motors can also be equipped with thrust bearings for high axial and radial loads.
• Wide range of connection systems for large cable cross-sections, high short-circuit strength or phase-segregated version.
• Optimized starting and operating parameters and high efficiency by using copper bar rotors as standard.
• With water jacket cooling, IC71W up to 60 % higher power density - compact and low noise. Admirably suited for converter operation with constant load torque and wide field-weakening range.
• Complies with almost all of the user requirements and specifications (no deviation philosophy)
• High level of acceptance in the various sectors. For instance, Shell and DOW recommend these motors
• Complete project documentation guarantees minimum planning costs
• High degree of cost effectiveness and low operating costs as a result of the optimum electrical and mechanical values
• High degree of variability and versatility using a welded steel enclosure (to adapt the dimensions, mounted components)
