    High Power Density

    Comparing with same size but different type motors, BLDC slotless has more power density than others. With 7.24cm3 volume, ECU16 motor can deliver near 12W power.

    Wide Operating Range

    We extend the operating range of motors by optimized electromagnetic and mechanical design.

    Smaller Speed/Torque Gradient

    Smaller speed/torque gradient means more powerful motor, comparing with competitor, MOONS' ECU16 motors have 15% - 25% improvement .

    Performance Advantage

    For same output power, MOONS' have less loss than competitor, At the no load condition, MOONS' have 33% lower temperature rising than competitor.
