The G500-S + M550-V + i650 motec combines the IE6 M550-V motor with a G500-S shaft-mounted helical gearbox. Top-level IE6 efficiency to IEC TS 60034-30-2 (Grade 1 to GB 30253-2024 for China) comes in the same footprint as an IE3 drive, cutting energy demand and the resulting CO₂ emissions throughout operation.

The i650 motec frequency inverter mounted on the motor provides stepless speed control, making the unit suitable for a broad range of tasks. Sensorless operation still yields up to 300% starting torque from standstill, and the drives can be used worldwide with most common approvals. The i650 motec adds extended functions such as Logic PLC, table positioning and Safe Torque Off (STO) via CIP Safety.

The G500-S shaft-mounted helical gearbox mounts directly on the machine shaft in a slim, space-saving housing, combining high radial load capacity with finely graded ratios and low backlash. Available in 2-, 3- and 4-stage versions, the series covers 0.25 … 7.5 kW and 5 … 4500 Nm, with ratios up to i = 4640.

Features

IE6 efficiency class

IE6 to IEC TS 60034-30-2 and Grade 1 to GB 30253-2024 represent the highest efficiency level.

Up to 300% starting torque

Very high starting torque from standstill is achieved in sensorless operation.

Minimal energy and CO₂

Energy demand and CO₂ emissions during operation are minimized in an IE3-sized frame.

Integrated i650 motec inverter

The on-motor inverter provides stepless speed control without a separate cabinet inverter.

Extended functions

Logic PLC, table positioning and Safe Torque Off (STO) via CIP Safety are available.

Slim shaft-mounted gearbox

The compact housing mounts directly on the machine shaft and offers low backlash with ratios up to i = 4640.

Applications

  • Conveyor drives mounted directly on the machine shaft
  • Warehouse logistics and automated storage systems
  • Courier, express and parcel facilities
  • Textile and woodworking machinery
  • Decentralized drive architectures
  • Machine axes requiring simple positioning and STO
