Energica Motor Company SpA, which we know in particular with the Moto-E, has joined forces with the Italian electric motor specialist Mavel to offer a brand new motor to equip its machines. It is called EMCE, short for “Energica Mavel Co-Engineering”, and will equip its entire range of electric motorcycles. Thanks to the new engine, the entire range will now benefit from significant improvements in power and efficiency, with an impressive drop in weight.
The EMCE launch was planned for 2022, but following global supply chain challenges due to the health situation, the company decided to accelerate development and launch the EMCE motor and inverter earlier.
Thus, Energica specifies that it is a 300 V Hybrid Synchronous Motor (HSM), liquid cooled, with an inverter with adaptive control. The motor and inverter now share a liquid cooling system, which both simplifies the overall design and also results in greater thermal efficiency.
Overall, Energica makes a lot of promises with its description of all the benefits the EMCE has to offer: lower center of gravity coupled with a 10kg weight loss compared to the previous version, higher power, increased autonomy and significantly reduced maintenance intervals.
This new EMCE engine sees its power increased to a peak of 126 kW (169 hp) at 8 rpm, with an average power reaching 500 kW (108 hp). Energica motorcycles will now be 147 kg lighter, with a relative increase in autonomy of 10 to 5% depending on driving style.
To achieve these power and efficiency gains, the partnership has worked on a number of innovations in the new engines. The motor's rotor and stator have an "innovative geometry that minimizes energy loss and maximizes performance." The homogeneity of the torque delivered and the optimization of the masses make the engine unique in terms of power and torque density and allow the optimization of production processes.
Its adaptive control algorithms ensure that the inverter is always able to operate the system as efficiently as possible. The electric motor also includes patented sensors capable, among other things, of collecting and storing motor operating data to predict the occurrence of any mechanical failure.
The use of a liquid cooling system allows for better thermal conditioning of the motor and inverter, which results in the ability to work with higher torque and power density which even with a smaller motor and lighter, result in greater acceleration.
The transition from oil cooling to liquid cooling of the EMCE engine is a further demonstration of the technological advances which, year after year, contribute to the successes of Energica Motor Company SpA.
