g500-S shaft-mounted helical geared with AC motors  MD for Mains operation or Inverter operation

In combination with three-phase AC motors, our shaft-mounted helical gearboxes form a compact and powerful drive unit. Numerous

options at the input and output end provide for the drive to be exactly adapted to your application.

The slim shaft-mounted helical gearboxes feature high reliable radial forces, closely stepped gear reductions and a low backlash. They are available in 2-stage and 3-stage design with a torque up to 4500 Nm (Mains operation) or  up to 19000 Nm (Inverter operation) and a ratio of up to i= 430.

Three-phase AC motors as a basis for geared motors

In a power range of 0.12 to 30 kW  (Mains operation) or 55 kW (Inverter operation), Lenze offers mains-operated three-phase AC motors for basic and comprehensive tasks.
These drives come in different efficiency classes and can be used for the versions required for mains operation or he versions required for the versions required for open-loop or closedloop controlled inverter operation.

• IE1 motors up to a power of 0.55 kW

• IE3 motors from 0.75 kW to 30 kW (Mains operation) or 55 kW (Inverter operation)

Versions

• Slimline design saves installation space of the machine

• Solid shaft, hollow shaft and shrink disc for direct integration into the machine

• High accuracy with axial output provide for the highest efficiency

Customer benefit

• Different efficiency classes for the greatest economic benefit

• Saving of space by compact direct mounting to Lenze gearboxes
