Application Scenarios of Outer Rotor BLDC Motors

Our low-noise outer-rotor BLDC motor for air purifier has 12V and 24V versions. Power ranges from 15W to 48W, torque 70–148mN.m, speed adjustable 200–2000RPM to match different filter resistance. Idle current is under 0.3A to save electricity. We can customize shaft and mounting size to fit your air duct directly. Low noise and little vibration, perfect for all-day running purifiers.

This outer rotor BLDC motor comes in 12V/24V, max torque 100mN.m for soft natural wind. Wide speed range supports multiple wind speed settings for control boards. Compact body leaves more space for fan circuit and swing parts. Torque stays consistent when switching speeds, wind volume won’t jump up and down.

The 24V high-torque outer rotor BLDC motor outputs 100–300mN.m torque and works fine in humid bathroom environments. Medium torque types suit dehumidifiers for fast moisture removal, high torque ones deliver strong hot air for bath heaters. Moisture resistant design, no overheating even with long continuous running.

Mini 12V low EMI medical BLDC motor outputs steady 30mN.m torque, idle current below 0.3A to reduce heat. It runs quietly with low electromagnetic interference, won’t disturb patients or mess up precise medical devices. Small size fits compact portable medical fans and air pumps.

24V energy- saving outer rotor BLDC motor balances wind volume and low power consumption, won’t drain car batteries fast during long outdoor use. Integrated outer rotor structure resists vibration well, speed stays smooth on bumpy roads. Small enough to be installed inside vehicle shells with adjustable speed.

This general-use outer rotor BLDC motor adjusts speed from 300 to 1800RPM to meet different cooling demands of cabinets and charging piles. Stable torque supports 24-hour non-stop operation. Low idle current lowers the power load of whole equipment, and it can stand slight dust in workshops.
