Otis Triple-phase Async Motor YVP90-6B1 – Silent, Vector-Ready Power for Modern Elevator Drives | Nanjing Zhuye Elevator Parts
Every smooth Otis ride begins with a quiet revolution — 1,000 of them per minute. The YVP90-6B1 triple-phase asynchronous motor is that powerhouse. Rated 2.2 kW at 380 V, 6-pole, 1,000 rpm, it is built for vector drives (VFD), regenerative braking and 24-hour duty in Gen2® Switch, 4200 and modernisation packages. When windings burn or bearings howl, the car jerks, levels poorly, or refuses to start. Nanjing Zhuye Elevator Parts keeps genuine YVP90-6B1 motors in OEM packaging, ready for next-day despatch worldwide — helping you restore whisper-quiet power without costly OEM delays.

Installation method – 45-minute precision swap
-
Place lift on inspection mode; stop at mid-shaft; switch OFF main breaker; lock & tag.
-
Remove motor cover; photograph encoder, brake and power connections.
-
Release brake; sling motor; remove coupling bolts and earth strap.
-
Slide old motor out; clean flange face and keyway.
-
Insert YVP90-6B1; torque M10 flange bolts to 45 Nm in star pattern.
-
Install key, coupling, brake disc; torque coupling to 30 Nm.
-
Connect 3-phase L1/L2/L3, earth 6 mm², encoder (EnDat 2.2), brake 24 V.
-
Power up; run auto-tune via Otis Drive Tool (ODT-6B1); 120 s vector calibration.
-
Run 20 full-speed cycles; verify temperature < 65 °C and no vibration > 1 mm/s.
-
Apply torque-stripe paint; log serial number and test date in maintenance book.
Replacement cycle & preventive maintenance
Otis bulletin SB-MOT-2024-03 recommends:
-
Visual inspection every 6 months: check for oil, loose bolts, bearing noise.
-
Vibration test every 12 months: RMS < 1 mm/s, bearing temperature < 65 °C.
-
Replace entire motor every 10 years or 30 000 operating hours, whichever comes first.
-
Immediate replacement if:
– insulation < 1 MΩ between phases and earth,
– bearing noise > 55 dB(A) or temperature > 75 °C,
– encoder error frames > 1 % after cable swap,
– vibration > 2 mm/s RMS.
Pro tip: 70 % of premature failures are traced to loose coupling bolts — re-torque to 30 Nm every year.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use EnDat 2.2 encoder cable; generic cables cause position drift.
-
Never pressure-wash the motor; water kills IP55 in minutes.
-
Keep a spare YVP90-6B1 in every high-rise store; at 18 kg it fits on a shelf and saves a week.
-
After heavy rain, run empty car and check bearing temperature < 65 °C.
-
Order the “Motor Kit” (YVP90-6B1 + coupling + key + calibration certificate) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
