The honest comparison our engineers walk every customer through before selection.
| Factor | Direct-Drive MDR | Geared Roller | Linear Motor (LIM / LSM) |
|---|---|---|---|
| Drive principle | PM motor direct drive, no gearbox | Geared motor + roller drum | Direct electromagnetic thrust |
| Speed control | Servo precise, wide speed range | Fixed or limited range | Servo precise, fast response |
| Torque behavior | Constant torque across range | Torque drops at low speed | High continuous thrust |
| Output speed range | Wide range, constant torque | Narrow, geared steps | Programmable profiles |
| Energy use | −25% vs geared | Baseline | LSM −60~65% vs LIM |
| Wear & maintenance | Fewer wearing parts | Gear wear, lubrication service | No mechanical contact |
| Positioning accuracy | Millimeter-level feedback option | Limited | Precise trajectory control |
| Lead time | Short, in-house production | Medium | Short vs international brands |
| Best for | CBS, wheel sorter, DWS, induct, conveyors | Simple belt / roller conveyor | High-speed cross-belt sorters |
