Motors So Quiet,
You Barely Notice Them

The motor is the heart of any motorized curtain system — and the detail that most readily reveals its quality. Wintom's self-developed DC tubular motor, combined with soft-start/soft-stop algorithms and multi-stage planetary gearing, keeps operating noise below 30dB — lower than the nighttime background noise standard for hotel guest rooms, ensuring guests sleep undisturbed even when curtains are in motion.

4 Types of Spaces,
4 Noise Challenges

Curtain motor noise is rarely about whether it is “loud” — it is about whether guests will complain. 30dB is the critical threshold: below it, motor operation is virtually imperceptible; above it, the motor becomes an obvious noise source in quiet environments.

  • Hotel Guest RoomGUEST ROOM
    Guest Room nighttime background noise is around 25-30dB. Standard motorized curtain motors run at 40-45dB, easily waking light-sleeping guests when curtains open or close.
  • Hospital WardHOSPITAL
    Hospitals demand stricter noise control. Post-surgery patients are sensitive to sudden noises; motor impact sounds can disrupt rest and recovery.
  • Meeting RoomMEETING ROOM
    Adjusting curtains during a meeting causes motor noise that interrupts speakers and interferes with recording. Remote meeting microphones are especially prone to picking up mechanical noise.
  • Luxury ResidenceRESIDENCE
    Home environments have decreasing tolerance for appliance noise. Bedrooms, studies, and home theaters require curtains that operate quietly at any hour.

3-Layer Noise Reduction
Eliminating Noise at the Source

Wintom's silent drive solution does not simply wrap the motor in sound-absorbing cotton. It systematically reduces noise across three layers: motor structure, drive algorithm, and mechanical transmission.

01
Soft-Start / Soft-Stop AlgorithmEliminating Impact Noise
Our proprietary drive algorithm controls the motor acceleration/deceleration curve — gradual ramp-up on start, gradual fade on stop — eliminating the sharp “click” impact of traditional motors at start/stop. This is the noise guests perceive most readily.
02
Multi-Stage Planetary GearingReducing Mechanical Friction
High-precision multi-stage planetary gear reducers reduce gear meshing noise by 8-10dB compared to standard worm-gear drives, while simultaneously improving torque output efficiency.
03
DC Brushless Tubular MotorLow-Noise Operation
Compared to AC motors, the DC brushless motor has no carbon-brush friction or electromagnetic noise. Rated operating noise stays below 30dB, with longer service life and lower heat generation.
