  • GXM-F

    ㆍElectric vehicles without a multi speed transmission are forced to rely entirely on motor output to cover launch acceleration cruising efficiency and high speed driving.

    This creates an inherent compromise where low speed torque efficiency and high speed efficiency cannot be optimized at the same time.

    With a three speed layout, GXM-F allows first gear to compensate for vehicle mass and launch load, while third gear extends cruising efficiency and vehicle speed without forcing the motor into inefficient operating conditions.

    As a result, a 3000 watt motor equipped with GXM-P can deliver performance and real world efficiency that cannot be achieved even with larger 4000 or 5000 watt motors using single reduction systems.

    As a result, a 120 kilowatt motor equipped with GXM-F can deliver higher real world performance and efficiency than single reduction systems that rely solely on increased motor output.

    Unlike conventional internal combustion vehicle transmissions, GXM-F does not require clutches torque converters or complex hydraulic shifting systems.

    Through F·Link Shifting, gears remain disengaged when rotational conditions are not aligned and engage only at the correct moment through direct mechanical linking.

    This enables smooth and efficient shifting under load using a mechanically simple structure optimized specifically for electric motors rather than combustion engines.

GXM-F

  • ㆍBy integrating GXM-F, system level optimization becomes possible across the entire vehicle powertrain.

    Reduced reliance on excessive motor torque lowers thermal stress inverter load and peak battery demand while improving overall efficiency.

    This results in improved driving range reduced component cost enhanced durability and long term system reliability.

    GXM-F is therefore not merely a transmission component but a system level solution that improves performance efficiency and total vehicle cost simultaneously.

    Electric motors do not operate at peak efficiency across their entire speed range.

    There is always a defined rated efficiency speed window where power output electrical consumption and thermal behavior are optimally balanced.

    When used with a multi speed transmission, even high power automotive electric motors achieve their highest efficiency within a relatively narrow and stable rotational range.

    In a three speed GXM-F system, the motor is designed to operate primarily within 3000 to 4500 rpm, where efficiency stability and thermal balance are maximized.

    Below this range, excessive current is required to generate vehicle launch torque, increasing thermal stress on the motor inverter and battery system.

    Above this range, over speed operation increases electrical and mechanical losses without meaningful efficiency gains.

    Single reduction drivetrains therefore force high power motors to operate outside their optimal efficiency range during launch hill climbing or sustained high speed driving

    GXM-F’s three speed transmission allows gear selection to match vehicle load and driving conditions so the motor can remain close to its 3000 to 4500 rpm rated efficiency windowduring launch acceleration urban driving highway cruising and high speed operation.

    As highlighted in the table, the colored zones indicate the motor’s rated peak efficiency range.

    Compared side by side, the difference is clear: with GXM-P’s 3-speed transmission, the motor remains within its optimal efficiency window across a wide range of vehicle speeds, while a fixed reduction system quickly pushes the motor outside this range as speed increases.

    As a result, a 120 kilowatt motor equipped with GXM-F delivers stronger real world performance while reducing unnecessary current draw heat generation and system stress.

    This improves overall vehicle efficiency and extends the operating life of the motor inverter and battery as a complete powertrain system.
