Elevator SMART Inverter 11 kW SMART100-LR-4011-H3 – The Silent Power-Plant Behind Every Modern Ride

Passengers judge an elevator by the smoothness of the start, the steadiness of the ride and the accuracy of the stop. What they never see is the 11 kW “brain” that converts incoming three-phase power into infinitely variable torque. The SMART100-LR-4011-H3 is a purpose-built lift inverter for gearless PM machines, already field-proven on 1.0 – 2.5 m s⁻¹ passenger elevators and 0.5 m s⁻¹ heavy-duty freight cars. Nanjing Zhuye Elevator Parts keeps factory-sealed units in stock for 24-hour despatch. Below we decode the part number, show a 30-minute replacement, and give the preventive-maintenance cycle that turns expensive “jerky ride” callbacks into planned five-minute PM tasks.
1. Decoding the Model Number
-
SMART100 = 100 A IGBT platform (400 V class)
-
LR = lift-regenerative (AFE front-end, 4-quadrant)
-
4011 = 40 HP / 11 kW continuous @ 40 °C ambient
-
H3 = harmonic filter + built-in 3 % reactor, EN 61000-3-12 compliant
Result: 98 % efficiency, THDi < 5 %, regenerative energy pushed back to the grid instead of being wasted as heat.
2. Where the Inverter Is Used
-
Gearless PM synchronous machines 8 – 30 kW name-plate
-
Machine-room-less (MRL) systems up to 30 floors
-
Modernisation packages replacing 20-year-old six-pulse drives
-
Simplex or group (≤8 cars) with incremental or Sin-Cos encoder
3. Daily Operation – What the Inverter Actually Does
-
0 Hz full-load pre-torque for absolutely level door sills
-
S-curve generator (jerk ≤ 0.7 m s³) for boutique-hotel comfort
-
Stand-by power < 18 W (fans sleep, DC bus stays alive)
-
Auto-identify motor parameters in 90 s—no oscilloscope needed
-
Built-in brake chopper and 2 % duty braking resistor for emergency stops
4. Installation – 30-Minute Swap
Safety: lock main breaker, verify DC bus < 50 V with meter, tag out.
Step 1 – Photograph existing wiring; note encoder type (incremental 1024 ppr or Sin-Cos 1 Vpp).
Step 2 – Undo four M6 mounting bolts; slide SMART100-LR-4011-H3 out of chassis.
Step 3 – Disconnect (in order) three-phase input, three-phase output, encoder, braking resistor and earth.
Step 4 – Inspect contactor tips; if > 1 mm pitting, replace (Nanjing Zhuye part LC1-D4011).
Step 5 – Lift new inverter into place; torque bolts 12 N m.
Step 6 – Re-connect cables—keyed plugs prevent phase reversal.
Step 7 – Power up; keypad shows “0.00”, auto-tune runs 90 s, then “Ready”.
No laptop is required; all parameters are pre-loaded for 11 kW PM motor.

5. Replacement Cycle & Preventive Maintenance
-
High-rise office (>1,000 starts day⁻¹) – vacuum heat-sink every 6 months, replace inverter every 10 years
-
Residential tower (300–600 starts day⁻¹) – inspect annually, replace every 12 years
-
Low-rise freight (≤200 starts day⁻¹) – inspect every 18 months, replace every 15 years
Replace immediately if:
-
DC bus ripple > 5 % (capacitor ageing)
-
Fan noise > 65 dB(A) or bearing temperature > 70 °C
-
IGBT short logged ≥2 times in 30 days
-
Brake chopper fault “OH” appears at ambient < 40 °C
-
Output current unbalance > 5 % (phase reactor failure)
6. Extending Life – 3 Pro Tips
-
Keep ambient < 40 °C; every 10 °C rise halves electrolytic life
-
Torque cable lugs to 20 N m; loose connections cause arcing and void warranty
-
Run built-in “capacitor forming” routine if lift is idle > 6 months—prevents DC bus collapse

Conclusion
The SMART100-LR-4011-H3 11 kW inverter is the silent power-plant that turns electricity into silky motion. One capacitor fault can park a car for hours. Keep a spare unit from Nanjing Zhuye on every service truck, swap it on schedule, and replace “jerky ride” panic with a five-minute planned fix—one smooth, energy-saving floor at a time.
