OTIS Door Motor XRDS-80J/150J – Compact Torque for Whisper-Quiet Door Motion | Nanjing Zhuye Elevator Parts
First impressions start with the door. The Otis XRDS-80J (80 W) and XRDS-150J (150 W) permanent-magnet servo motors turn every opening into a silent ballet—adaptive torque, predictive braking and ≤ 50 dB(A) at 1 m, while keeping closing force under 150 N. Built for Otis XRDS V1.0 and V2.0 operators, they open 1,100 mm panels in < 2.2 s and survive 3 million cycles without maintenance. When the encoder drifts or bearings growl, passengers feel a shudder or nudge-loop. Nanjing Zhuye Elevator Parts keeps genuine XRDS-80J/150J motors—complete with encoder, key and IP65 cable—in stock for next-day despatch worldwide, helping you restore premium door motion without costly OEM delays.

Where it works
-
Otis XRDS V1.0/V2.0 side-opening and centre-opening operators
-
Gen2® Life, Gen2® Switch, 4200/5200 modernisation packages
-
Any door panel 600-1 400 mm wide, 80-180 kg mass, belt or linear magnetic drive
Installation method – 20-minute field swap
-
Place lift on inspection mode; open doors manually; switch OFF local breaker; lock & tag.
-
Remove operator cover; release belt tensioner; photograph encoder and power connectors.
-
Unbolt motor (4 × M6); pull straight to avoid encoder damage.
-
Clean mounting face; apply new gasket (supplied).
-
Insert XRDS-80J/150J; torque M6 bolts to 8 Nm in diagonal pattern.
-
Install key, pulley, belt; tension to 2 % of length (deflection 6 mm at 200 mm span).
-
Connect encoder (8-pin) and 24-48 V power (2-pin); verify Hall LED blinks once per revolution.
-
Power up; run auto-learn via Otis XRDS Tool (OXR-2.8); 90 s cycle learns inertia, friction, encoder offset.
-
Execute 50 continuous cycles; verify temperature < 50 °C on flange and no fault codes.
-
Apply torque-stripe paint; log serial number and date in maintenance book.
Replacement cycle & preventive maintenance
Otis bulletin SB-XRDS-2025-01 recommends:
-
Visual inspection every 6 months: check encoder alignment, loose bolts, bearing noise.
-
Encoder test: oscilloscope trace must show clean 0-5 V square wave; replace motor if jitter > 5 %.
-
Bearing test: rotate by hand; roughness or axial play > 0.1 mm means bearing failure—replace immediately.
-
Replace entire motor every 12 years or 3 million cycles, whichever comes first.
-
Immediate replacement if:
– motor stalls with < 50 % rated torque (magnet demagnetisation),
– encoder Hall error persists after cable swap,
– temperature > 70 °C on flange (fan blocked),
– belt slips after re-tension (pulley worn).
Pro tip: 60 % of premature failures are traced to over-tensioned belts—keep deflection at 2 % of span.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use the supplied key; loose keys ovalise the shaft and destroy the encoder disk.
-
Never pressure-wash the motor; water enters the bearing and locks the encoder.
-
Keep a spare XRDS-80J/150J in every service van; at < 2.5 kg it costs less than one callback night.
-
After heavy cleaning, run 5 cycles to redistribute grease inside bearings.
-
Order the “XRDS Motor Kit” (motor + key + gasket + encoder plug) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
