Motenergy ME1302 Water-Cooled Brushless


Motenergy 1302 Dual Stator Water-Cooled Brushless Motor with Sin/Cosine Encoding. Plumbing is not included but uses 18mm tubing. Similar to the 1115 Motor we've been using but with a sealed enclosure. 

Designed for long life. No brush maintenance. The motor is 92% efficient at voltages between 24 to 96 VDC. Continuous current of 125 amps AC (180 Amps DC into the motor control). This is a 3-phase, Y-connected Permanent Magnet Synchronous Motor with an axial air gap. It has two stators with a rotor in the center.


  • 4 pole motor (8 magnets) 
  • Maximum recommended rotor speed 5000 RPM
  • Voltages from 24 to 96 VDC 
  • Torque constant 0.15 Nm per Amp
  • Phase to Phase winding resistance 0.013 Ohms
  • Phase to Phase Inductance is 0.10 mH, 28 turns per phase
  • Armature Inertia is 45 Kg Cm squared
  • Peak phase current 420 Amps for 1 minute (600 Amps DC into the controller)
  • Weight 35 pounds
  • Peak Stall Torque 60 Ft-Lb. 

Provide your own small radiator and water pump with a flow rate of 4-10 liters per minute.
