RMD-FLO Series Naming Conventions
Example format: RMD - FLO - 70 - 15 - 200
- RMD: Brand Name (R-Reducer, M-Motor, D-Drive)
- FLO: Series name (outer rotor frameless torque motor)
- 70: Rotor outer diameter 70mm
- 15: Stator stack height 15mm
- 200: Rated power 200W
For example: RMD-FLO-90-15-400 where 90 is rotor outer diameter, 15 is stator stack height, and 400 is rated power.
