E-Skateboard
EMEC Involved in the Development of an E-Skateboard
A sports student approached EMEC with the idea of entering the rapidly growing market for electrically powered skateboards. As the technical expertise was lacking and the financial resources were not sufficient for EMEC to fully develop the product, EMEC took part in a start-up joint venture.
Brief
The technical specification was adopted in the project implementation by EMEC Prototyping. The aim was to make the skateboard's drive as unobtrusive as possible. In addition, the typical skateboard feeling was to remain unaffected. Another objective was to keep the weight of the e-skateboard as low as possible. Good coordination of the overall system should enable safe riding. In particular, in addition to the safety requirements, the fun of riding should not be lost.
Challenge
The biggest challenge was to integrate the drives into the existing installation space of a skateboard. Several concepts were developed and examined for this purpose. The state of the art at the start of the project was e-skateboards with a belt drive. Although this offered the possibility of generating large drive torques, it was also relatively large. It was also a major challenge to fit the energy storage and power electronics compactly into the installation space.
After an in-depth methodical concept and solution search, a direct wheel drive was selected for the optimum drive implementation. Although this represents the greatest technical risk in development, EMEC had already developed direct drives for cordless tools and therefore had the necessary expertise in this area. In addition, this type of drive (with the exception of systems with disengagement) has the least impact on driving dynamics and can also be used very effectively for recuperation of braking energy. As there is no gearbox, the drive can also be integrated extremely compactly into the axle. The energy storage unit, which was placed close to the axle for balance reasons, also made it possible to design and implement the entire system as an interchangeable system for different skateboards.

Results
The resulting electric drive for e-skateboards is one of the most compact and lightest drives on the market. The range can also be flexibly configured thanks to the battery exchange system. The first generation of the prototype was already a lot of fun to ride. Further product development will include some exciting topics such as ABS and interconnectivity. Due to the dynamic market, further development requires a great deal of innovative strength and flexibility.
