Brushless Motor For Car Wash Equipment And Tunnel Systems.

Car wash motors live in water, chemicals and humidity every working hour. A brushless DC motor seals against high-pressure spray, resists detergent and acid chemistry, and outlasts brushed drives by years in this punishing environment. Shenghe builds IP65/IP67 BLDC motors with stainless shafts for brush rollers, conveyor chains, drying fans and chemical dosing pumps.

  • 24V / 48V with IP65 / IP67 sealing
  • 200W — 1500W rated power range
  • Stainless steel shaft standard
  • Planetary and worm gearbox options

Why BLDC In Car Wash

What Makes Brushless Motors Survive The Wash Bay Environment

  • IP67 sealing withstands direct high-pressure water jets
  • Stainless steel shaft resists detergent, acid and wax chemicals
  • No brush wear means zero maintenance in wet, humid conditions
  • Variable speed adapts brush roller RPM to vehicle size and speed
  • 15,000+ hour life versus 3,000 hours for brushed alternatives
  • No spark risk near water and chemical mist
