Specification — 48V 500W

48V 500W Brushless DC Motor For EV Auxiliaries, Heavy Conveyors And Compressor Drives.

500W on a 48V bus draws just over 12A — a current level that standard automotive connectors and mid-gauge cable handle with ease, yet the mechanical output is enough to run EV air-conditioning compressors, power steering pumps and heavy conveyor segments carrying 100–200 kg per metre. This power class bridges the gap between lightweight 400W drives and the full-industrial 750W frame, offering maximum torque density in a compact 80mm housing.

  • Rated voltage 48V DC (36V–58V operating range)
  • 500W continuous rated power
  • 80mm frame, extended stack length
  • Hall sensor standard, resolver or encoder optional
Why 48V 500W

Benefits Of The 48V 500W Power Class

  • 25% more torque than 400W in the same 80mm frame — longer lamination stack, not a bigger motor
  • 12A rated current keeps wiring and connector costs in the automotive-grade range
  • 2.5x peak torque capability handles compressor startup and conveyor jams
  • Direct fit on 48V EV platforms — shares the same battery bus as traction and BMS
  • 87–89% efficiency at rated load reduces waste heat in sealed EV compartments
  • Planetary or worm gearbox option for output torque up to 90 Nm

Common Applications For 48V 500W BLDC Motors

  • EV auxiliary drives: Electric power steering pumps, A/C compressors and coolant pumps on 48V mild-hybrid and full-EV platforms
  • Heavy conveyor segments: Chain and belt conveyors handling 100–200 kg/m loads in manufacturing and distribution
  • Compressor drives: Scroll and reciprocating compressors for vehicle HVAC, portable air tools and refrigeration units
  • Material handling: Powered roller conveyors, lift table actuators and pallet shuttle drives in warehouses
  • Marine auxiliary: Bilge pumps, anchor windlass drives and trim-tab actuators on 48V boat electrical systems
  • Agricultural equipment: Seed-drill metering drives, sprayer pump motors and greenhouse ventilation on solar-battery 48V systems

Technical Details For Integration

  • Battery: 13S or 14S Li-ion, 16S LiFePO4; 20–60Ah depending on run-time requirement
  • Controller: 48V 20A FOC driver with field weakening for extended speed range above base speed
  • Thermal class: Class F (155°C) insulation standard, Class H (180°C) for sealed or high-ambient use
  • Mounting: B14 flange (4x M5) standard, B5 flange and face-mount for compressor coupling
  • Shaft: 14mm keyed standard, 19mm keyed for heavy-duty gearbox coupling
  • Vibration: Dynamic balancing to G2.5 grade per ISO 1940 for smooth compressor drive
