Helical-worm geared motors

Comparatively economical motors equipped with right-angle gearboxes and possessing a high power density. They can easily be integrated in machinery using mounting surfaces provided on three sides of the gearbox and the output-side pitch circle.

Input variants 

• Geared motor
• Geared motor with integrated frequency inverter
• Bearing flange for IEC standard motors
• Free input shaft
• Compact unit

Output variants

• Solid shaft
• Hollow shaft
• Hollow shaft with shrink disk
• Foot
• Flange
• Centred pitch circle

Lenze helical-worm geared motors are available in a performance range from 0.12 kW to 9.2 kW. The wide ratio range up to i = 1847 - combined with the small stage interval = 1.12 - permits exact selection of the required output speed. 

The options offered by the modular motor design ensure high flexibility. The motors are reliable in operation as the insulation material/s used is/are of the classification/s F and IP 55. The winding of double-enamel-coated wiring with additional phase insulation is highly resistant to breakdown voltage and mechanically particularly rugged. Complete drives with variable speed capacity can be realised by perfectly attuned combination with a frequency inverter.

Our helical-worm geared motors with integrated motec frequency inverter are the answer if you�re looking for compact decentralised drives
