E-bike – hub motor
The hub motor is a result of domestic know-how, designed with the most state-of-the-art approaches and simulation tools which allow us to use the materials efficiently. This reduces the environmental burden and complies with the required market guidelines, pursuing Domel’s development vision.
Domel’s direct drive motor for e-bike applications with the “pedelec” system does not use any pinions or gears. With its high efficiency, low weight and low noise, it is a very competitive product on the market with an excellent weight to torque ratio. Low energy consumption at a nominal power of 250 W and 25 km/h, and maximum power of 650 W allow a longer range on a single battery charge. The motor is designed in accordance with the 15194 standard for e-bikes.
The hub motor has been developed and tested up to the sampling phase.
