The honest comparison our engineers walk every customer through before selection.
| Factor | Direct-Drive MDR | Geared Roller | Linear Motor |
|---|---|---|---|
| Drive principle | PM motor direct drive, no gearbox | Geared motor + roller | Direct electromagnetic thrust |
| Speed control | Servo precise, wide speed range | Fixed / limited range | Servo precise |
| Torque behavior | Constant torque across range | Torque drops at low speed | High continuous thrust |
| Energy use | −25% vs geared | Baseline | LSM −60~65% vs LIM |
| Maintenance | Fewer wearing parts | Gear wear, oil service | No mechanical contact |
| Best for | CBS, wheel sorter, DWS, induct | Simple belt / roller conveyor | High-speed cross-belt sorters |
