RG Series
RG Series Helical Geared Motors
Motor and gearbox as one unit — no coupling, no alignment.
Close-coupled helical geared motors with the pinion cut on the motor shaft. Fewer parts than a motor-and-gearbox pair, a shorter overall length, and nothing to align on installation.
- Power range
- 0.18 kW to 30 kW
- Ratio range
- 3:1 up to 200:1
- Output speed
- 7 rpm to 480 rpm
- Insulation
- Class F, IP55
Built for Duty
What separates the RG Series from a general-purpose drive.
Integral pinion
First-stage pinion cut directly on the motor shaft removes a coupling, a bearing pair and an alignment step.
Compact footprint
Shorter overall length than a comparable motor plus gearbox, which matters on crowded machine frames.
VFD ready
Class F insulation and a wide speed band suit inverter duty across the Ritron VFD range.
IP55 as standard
Dust and jet-proof enclosure for mill, plant and outdoor conveyor environments.
Brake and fan options
DC disc brake, forced-cooling fan and encoder mounts for positioning and hold-and-lower duty.
Common spares
Gear sets and bearings shared with the RH Series, so a plant stocks one set of consumables.
