    Advantages:

    *Ample Power Reserve and Strong Output: This motor has a rated power of 7000W, a peak power of 15-20kW, and a peak torque of 73Nm. 

    When paired with a gearbox, it converts high speed into high torque. Furthermore, it can stably output high torque under low current and 

    low speed conditions, providing ample power for vehicle start-up and hill climbing, avoiding sluggish driving due to insufficient power.


    *High Efficiency and Reliability: As a product of Quanshun Motors, it continues the brand's high efficiency characteristics, with an energy 

    efficiency ratio likely not lower than 93%, reducing energy loss and extending vehicle range. Its H-class insulation class allows it to withstand 

    high operating temperatures, and with air cooling, it effectively controls temperature rise during operation. In addition, its IP67 protection 

    rating completely resists dust intrusion and can withstand short-term water immersion, enabling it to cope with complex environments 

    such as dusty and rainy days, extending the motor's service life.


    *Lightweight Design and Good Adaptability: The motor weighs only 11.7kg, which is lighter than some motors of the same power level. 

    The mid-mounted design with a reduction gearbox minimizes the overall load on the vehicle, optimizes weight distribution, and enhances 

    handling agility. It also adapts to various vehicle models and installation layouts.


    Applicable Scenarios:

    *High-performance electric motorcycles: Especially suitable for motorcycling-type electric motorcycles. Equipped with this motor, vehicles 

    can reach speeds of 70-120 km/h, meeting the needs of ordinary electric motorcycle users seeking speed and power, and also suitable for 

    short-distance commuting.


    *Off-road mopeds: Its strong torque output and excellent environmental adaptability allow it to handle complex terrains such as steep slopes 

    and gravel roads common in off-road conditions, providing stable power for off-road riding. It is a suitable motor for off-road mopeds.


    *Customized electric special vehicles: Can be used in customized models such as small electric site vehicles and short-distance shuttle electric 

    scooters. These vehicles have certain requirements for power and handling. The high efficiency and lightweight characteristics of this motor 

    match their operational needs, while its stable performance ensures high-frequency daily operation.
