Brushless Motor For Solar Tracker Slew Drives.

Solar tracker drives need long-life motors that draw zero holding current, sit in outdoor weather for 10+ years and respond to tracking commands over CAN or RS485. Shenghe BLDC motors ship paired with worm-gear slew drives, IP65 sealing and matched controllers built for tracker duty cycles.

  • 24V / 48V tracker battery compatible
  • IP65 standard, IP66 optional
  • Self-locking worm gearbox, zero holding current
  • CAN / RS485 controller available

Why BLDC For Trackers

Long Life, Low Self-Consumption, Outdoor Durability

  • 20,000+ hours bearing life outlasts a brushed DC motor in outdoor duty
  • No holding current — worm gear self-locks between tracking steps
  • IP65 sealing protects from dust, rain and temperature cycling
  • Closed-loop Hall feedback gives precise angular position on each step
  • Matched controller uses battery-friendly quiescent current
  • No brush arcing in potentially flammable dust environments

Single-Axis And Dual-Axis Tracker Variants

  • Single-axis horizontal trackers: One slew drive rotates the panel row east-to-west. Typically 48V / 150-300W motor with a worm slew drive at 60:1 to 100:1 ratio.
  • Single-axis tilted trackers: Same drive family, angled support structure. Motor sized for the higher wind-load torque on tilted panels.
  • Dual-axis trackers: Two independent BLDC motors — primary azimuth and secondary elevation. Smaller motors possible because both axes share the load.
  • Rooftop mini trackers: 24V / 50-100W compact BLDC for small commercial installations.
  • Agrivoltaic trackers: Ruggedized IP66 sealing and higher output torque for wind-exposed farm installations.

Controller Features For Tracker Duty

  • CAN 2.0 or RS485 Modbus for tracker control network
  • Position-mode operation with encoder-free angular tracking via Hall + step count
  • Ultra-low quiescent draw when idle (battery preservation)
  • Current limiting prevents wind-gust overcurrent trips
  • Fault log retention for unattended field operation
  • Wake-on-command operation with low-power sleep between tracking events
