Helical geared motors

Parallel-axial solid-shaft geared motor models with foot or flange. As in all other models, the gearboxes are particularly smooth- and quiet-running thanks to optimised gear teeth geometry 

Input variants

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

Output variants

• Solid shaft
• Foot
• Flange
• Centred pitch circle

Lenze motors with helical gearboxes are available with a performance range from 0.12 to 45 kW. The large ratio range up to i = 330 combined with the small step interval = 1.12 permit precise selection of the output speed desired. 

The motors are also extremely flexible, many options being available thanks to the modular motor design. 

The motors are reliable in operation due to insulating material/s with the classifications F and IP 55. Windings of enamel-coated wiring with additional phase insulation are highly resistant to breakdown voltage and mechanically particularly rugged. In perfectly attuned combination with a frequency inverter or servo inverter, very flexible complete drives with variable speed capacity can thus be realised. Our motors with helical gearboxes and integrated motec frequency inverters are the right answer if you�re looking for a compact decentralised drive.
