Otis DO3000S Operator HBA24360AK3 – The 3 kW Silent Commander That Turns 24 VDC into Feather-Soft Door Motion

Every feather-soft “whoosh” you hear when Otis elevator doors glide open is orchestrated by a green, shoebox-sized powerhouse mounted above the header — the DO3000S Operator, part number HBA24360AK3. This third-generation 24 VDC, 3 kW permanent-magnet drive regulates torque, position and speed in real time while regenerating up to 25 % of braking energy back into the battery bus. Originally engineered for SkyRise®, Gen2-R2® and Chinese super-MRL systems, it is now the universal retrofit for any controller demanding ultra-quiet, energy-saving door motion. Nanjing Zhuye Elevator Parts keeps factory-sealed AK3 operators in anti-static stock for next-day despatch. Below we explain what the operator does, how to commission it in under 30 minutes, and the replacement cycle that prevents expensive “door drive fault” call-backs.
1. What HBA24360AK3 Really Is
-
Power: 24 VDC ±10 %, 125 A peak, 30 A continuous
-
Motor: 3-phase PM synchronous, 3.0 kW, 1,024 ppr encoder, 8-pole
-
Torque: 10 Nm rated, 25 Nm peak (300 %) for 5 s
-
Speed: 0–180 rpm, ±1 rpm accuracy, <52 dB(A) at 1 m
-
Regeneration: 4-quadrant IGBT feeds 25 % of braking energy back to 24 V bus
-
Housing: IP55 aluminium, -25 °C to +70 °C, vibration 20 g
-
Size: 240 × 140 × 110 mm — fits inside 220 mm deep headers
-
Firmware: pre-loaded V8.06; checksum matches Otis original 0x9C7E
If the operator stalls, the door stops, the controller logs “EF3 Door Drive Fault” and the car goes out of service.
4. Daily Operation – What the Operator Actually Does
-
Updates torque every 40 µs; stop jerk <0.3 m/s³ — passengers feel nothing
-
Auto-compensates for door mass; learns rubber ageing every 24 h
-
Built-in 24 h self-test — if encoder drift >0.2 mm, “Door Learn Fault” is logged
-
Regenerative braking feeds 25 % of door energy back to 24 V bus — saves battery life
-
Temperature sensor derates current above 70 °C — no summer shutdowns
5. Replacement Cycle & Preventive Maintenance
-
High-traffic metro (>1,500 cycles day⁻¹) – blow dust every 3 months, replace operator every 6 years
-
Shopping mall (600–1,000 cycles day⁻¹) – inspect annually, replace every 10 years
-
Low-rise office (≤400 cycles day⁻¹) – inspect every 18 months, replace every 12 years
Replace immediately if:
-
Encoder count error >2 pulses per revolution
-
Brake resistor temperature >120 °C with normal duty
-
Vibration >55 dB(A) at 1 m during run
-
Bearing temperature >65 °C after 10 min run
-
EEPROM error 0xE2 after power dip (parameter corrupt)
6. Extending Life – 3 Pro Tips
-
Keep 24 VDC ±5 %; spikes above 30 V destroy the on-board buck converter
-
Torque motor lugs annually; loose connections cause arcing and ozone
-
Clean encoder disk monthly; brake dust creates false counts
7. Why Buy HBA24360AK3 from Nanjing Zhuye Elevator Parts?

Conclusion
The Otis DO3000S Operator HBA24360AK3 is the invisible conductor that turns 24 VDC into ultra-quiet motion while giving 25 % of braking energy back to the battery. A single encoder fault can park a car for hours. Keep a spare AK3 from Nanjing Zhuye on every service truck, swap it on schedule, and replace “door drive fault” panic with a thirty-minute planned fix — one silky, silent entrance at a time.
