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
