Application — Elevator & Lift

BLDC Motor For Elevator, Lift And Dumbwaiter Systems.

Elevator drives demand absolute reliability, precise speed control and silent operation floor after floor. A brushless DC motor delivers higher efficiency than AC induction alternatives, integrates directly with battery backup systems and produces far less heat in the shaft space. Shenghe builds BLDC motors and planetary gear units engineered for passenger elevators, freight lifts, dumbwaiters and home lift applications.

  • 48V / 72V DC bus compatible
  • 200W — 3000W rated power range
  • Electromagnetic fail-safe brake standard
  • Encoder feedback for floor-level accuracy

Why BLDC For Elevators

Replacing AC Induction And Brushed DC Drives In Lift Systems

  • No brush wear eliminates carbon dust inside the shaft space
  • 90-94% efficiency reduces energy cost per trip and heat generation
  • Flat torque curve provides smooth acceleration and deceleration
  • Direct 48V/72V DC bus operation simplifies battery backup design
  • Below 45 dB(A) noise meets residential building requirements
  • Compact size fits inside traction machine housings and dumbwaiter frames

Typical Elevator Use Cases

  • Passenger elevators: Traction machine drive for 4-8 floor residential and commercial buildings
  • Freight elevators: High-torque geared drive for warehouse and factory goods lifts up to 2000 kg
  • Dumbwaiters: Compact motor-gearbox unit for restaurant, hospital and library material lifts
  • Home lifts: Battery-powered 48V drive for 2-4 floor private residences, no machine room required
  • Escalator handrail drives: Auxiliary BLDC motor for handrail speed synchronisation
  • Car parking lifts: Shuttle platform drive for automated multi-level parking systems

Safety And Technical Details For Lift Applications

  • Fail-safe brake: Spring-applied electromagnetic brake holds full load on power loss, meets EN 81 requirements
  • Encoder resolution: 1000 PPR incremental encoder enables floor-levelling accuracy within 2 mm
  • Thermal protection: PTC thermistor embedded in windings triggers controller shutdown before overheating
  • Regenerative capability: Motor generates power during descent, recoverable via DC bus or battery
  • Operating temperature: -10 C to +50 C covers machine room and shaft environments
  • Certifications: CE marking, compatible with EN 81-20/50 and GB 7588 elevator safety codes
