The Shenghe BL104 is a 48V 1000W L-type BLDC gear motor in the 104mm frame size. Five reduction ratios (30:1 to 100:1) step the 3000 rpm motor down to between 30 rpm and 100 rpm output, multiplying torque to between 76 N·m and 254 N·m. The 25mm hollow output shaft (with 22mm optional) and 120mm PCD mounting flange make this build a good fit for AGV traction in the 200-500 kg payload class, solar panel cleaning robots, heavy conveyor drives and material-handling end-of-line equipment.

All five reduction ratios share the same motor + gearbox housing — the application engineer selects the ratio based on the target output torque and speed.
| Reduction ratio | Output speed (rpm) | Output torque (N·m, at 80% gearbox eff) | Typical application |
|---|---|---|---|
| 1 : 30 | 100 rpm | ≈ 76 N·m | Lighter conveyors, medium-duty AGV traction, packaging line drives |
| 1 : 40 | 75 rpm | ≈ 102 N·m | AGV wheel drive (lighter chassis class), rotary platforms |
| 1 : 50 | 60 rpm | ≈ 127 N·m | Solar cleaning platforms, conveyor end-of-line drives, transfer stations |
| 1 : 75 | 40 rpm | ≈ 191 N·m | Heavier AGV chassis, indexing tables, lifting / tilting drives |
| 1 : 100 | 30 rpm | ≈ 254 N·m | Heavy material handling, transfer carts, high-torque end-of-line drives |
The 104BL frame shares one mechanical envelope (120mm PCD, 25mm hollow shaft) across four power levels. Step up to BL120 for sustained 1500W+ duty.
| Variant | Power | Motor torque (pre-reduction) | Output torque @ 1:100 |
|---|---|---|---|
| 104BL-200W | 200 W | ≈ 0.64 N·m | ≈ 51 N·m |
| 104BL-400W | 400 W | ≈ 1.27 N·m | ≈ 102 N·m |
| 104BL-750W | 750 W | ≈ 2.39 N·m | ≈ 191 N·m |
| 104BL-1000W (this page) | 1000 W | ≈ 3.18 N·m | ≈ 254 N·m |
For higher continuous power (1500W / 2000W) step up to the 120BL frame — see /48v-2000w-bldc-gear-motor/ for the BL120 SKU page. For lower power and smaller envelope (90W-400W in a 90mm frame), see /48v-400w-bldc-gear-motor/.
Same factory line means single warranty, single engineering contact, no integration finger-pointing.
Production applications with confirmed deployments across Chinese domestic and export projects.
Two BL104-1000W motors at 1:50 or 1:75 ratio drive a differential-steering AGV chassis in the 200-500 kg payload range. 127-191 N·m output is enough wheel torque for warehouse logistics, sorting line traction and small outdoor AMR platforms. See /bldc-motor-for-agv/ for the broader AGV catalogue.
For rooftop and small commercial PV cleaning platforms — sized between the lighter BL90 platforms and the heavy BL120 industrial-PV carts. The 25mm hollow shaft allows pass-through routing of fluid lines or sensor cabling in compact mobile cleaning robots. See /bldc-motor-for-solar-tracking/ for related solar applications.
End-of-line conveyor drives, transfer carts, indexing tables and packaging-line drives where 100-254 N·m output is required from a compact L-type envelope. The 5-ratio selection lets the same motor serve different conveyor speed targets without redesigning the mechanical mount. See /electric-tank-carrier/ for transfer cart applications.
Engineering selection flow for the BL104 1000W. Estimated 30 minutes from load calculation to RFQ-ready specification.
Compute required output Nm and rpm at the load. Cross-check against the 5-ratio table above to pick the smallest ratio that gives sufficient torque margin (typical: 1.5-2× load torque headroom).
25mm standard for new designs. Choose 22mm only if mating an existing drive shaft of that diameter. For OEM custom cross-sections, send drawing in RFQ.
BLD6010 (DC 80-220V) for systems that may scale; BLD22010 (DC 18-60V) for strict 48V-only AGV / outdoor robotics. Both 10A continuous with PID auto-tune.
120mm PCD flange. 8-wire bundle: UL1007 thick gauge U/V/W power + thin gauge HU/HV/HW Hall + 5V/GND. Default 1000mm cable; longer or custom connectors at factory line.
BLD6010 PID auto-tune at no load → re-tune under 50% load → limit first 100 hours to 80% rated load for gearbox break-in → full S1 continuous duty after break-in.

≈ 254 N·m at 1:100 ratio. Scales proportionally with ratio: 76/102/127/191/254 N·m at 30/40/50/75/100 reduction (all at 80% gearbox efficiency).
25mm standard, 22mm optional. Custom shaft cross-sections + keyway on RFQ.
BL104 (200W-1000W band, 25mm shaft, 120 PCD) is the compact option. BL120 (750W-2000W band, 30mm shaft, 140 PCD) is the heavy-duty option with more thermal headroom for sustained 1500W+ duty.
BLD6010 (DC 80-220V) or BLD22010 (DC 18-60V) — both 10A continuous, PID closed-loop, RS232/485.
