The KM276027 is the 4-pole, 3-phase, 230 VAC permanent-magnet synchronous motor that powers KONE’s MX10, MX20 and MiniSpace™ gearless machines from 320 kg up to 1,600 kg. Delivering 6.3 kW peak at 240 rpm, this compact motor generates the torque curve needed for 1.0 m/s to 1.75 m/s speeds while meeting IE4 efficiency and SIL 3 safety requirements. A single shorted winding or a cracked resolver will throw a “65” or “66” fault and take the car out of service. Nanjing Zhuye Elevator Parts keeps hundreds of genuine KM276027 motors in Rotterdam and Nanjing so you can restore traction the same week. Below is an 800-word field manual that explains correct usage, on-site commissioning and the replacement cycle that keeps your elevators energy-efficient and fault-free.
1. What the KM276027 does
-
6.3 kW S1 duty, 11 kW S5-60 % peak
-
Integrated 1,024 ppr resolver + KDL encoder for dual-channel position feedback
-
Class-H insulation (180 °C) qualified for 40 °C ambient hoist-ways
-
IP54 cast-iron frame with forced-cooling fan 24 Vdc, 0.35 A
-
CE marked to EN 81-20/50 and CSA B44.1 for 15-year design life
2. Tools to carry
-
KM276027 motor (Nanjing Zhuye part #KN-MOT-KM276027) on pallet with lifting eyes
-
10 mm, 13 mm, 18 mm socket set and torque wrench (10–100 N·m)
-
KONE E-Link Service Tool (EST) laptop
-
Oscilloscope or power analyser
-
Feeler gauges 0.05–0.2 mm
-
Motor lifting yoke rated 250 kg
-
Lock-out / tag-out kit
3. Installation – 90 minutes with a lifting beam
Safety: place the car on top-of-travel buffers, lock brake and verify zero energy on KDL bus.
-
Photograph existing power, encoder and fan connectors.
-
Attach yoke to motor eyes; raise until coupling is unloaded.
-
Remove four M12 base bolts; slide motor backwards 50 mm and lower to pallet.
-
Check coupling insert – replace if radial cracks >2 mm.
-
Position new KM276027; align motor shaft to within 0.05 mm TIR using dial gauge.
-
Torque base bolts to 60 N·m in diagonal pattern.
-
Connect power (U/V/W), resolver (X131) and fan (X20); tug-test each.
-
Power up – EST should show “Motor Ready” and 0 N·m at standstill.
-
Run a 3-cycle automatic tuning; verify torque ripple <5 % and dB(A) <55.
-
Record serial number, date and alignment values in CMMS.
4. Functional test – prove it to the drive
a) No-load current: 2.1 A ±0.2 A per phase at 50 Hz.
b) Resolver offset: electrical angle 0 ° ±1 ° after auto-tune.
c) Vibration: <2.8 mm/s RMS on motor frame (ISO 10816).
d) Temperature rise: <60 K above ambient after 30 min run.
e) Log all values in EST and export PDF for the site file.
b) Resolver offset: electrical angle 0 ° ±1 ° after auto-tune.
c) Vibration: <2.8 mm/s RMS on motor frame (ISO 10816).
d) Temperature rise: <60 K above ambient after 30 min run.
e) Log all values in EST and export PDF for the site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for oil leaks at seal and fan noise.
-
Quarterly – measure winding insulation >100 MΩ at 500 Vdc.
-
Annually – check coupling alignment; re-torque bolts to 60 N·m.
-
Every two years – replace fan (24 Vdc, 0.35 A) – bearing failure is the #1 cause of motor overheating.
6. Replacement cycle – duty and environment rule
KONE specification: 15 years. Nanjing Zhuye analytics refine this to real-world data:
-
Light duty (<150 starts/day, office): 18 years
-
Standard duty (150–400 starts, residential): 15 years
-
Heavy duty (>400 starts, hospital, mall): 12 years
-
High ambient (>40 °C, rooftop MRL): 10 years – insulation life halves every 7 °C rise.
Replace immediately if:
-
Winding insulation <10 MΩ – moisture or varnish degradation
-
Resolver offset drifts >5 ° – indicates cracked permanent magnet
-
Bearing noise >75 dB(A) or temperature >85 °C
-
Vibration >7.1 mm/s – risk of magnet detachment
7. Eco-disposal & warranty
Return the old motor on the original pallet; Nanjing Zhuye recovers copper, aluminium and rare-earth magnets and issues a €50 recycling credit. Every KM276027 ships with a 24-month replacement warranty, extendable to 60 months when you join our annual alignment-check program.
