Sevcon Motor Controllers Serve Electric Scooter Industry
With growing worldwide demand for electric scooters, Vmoto E-max has specified new advanced technology motor controllers from Sevcon that combine a compact size with high power capacity. Vmoto E-max, a publically listed Australian company with its European head office in Barcelona and distributors around the world, has turned to new Gen 4 digital controllers from Sevcon to meet the specific performance needs of various 50cc and 125cc equivalent electric scooters that utilize different types of PMAC motors. In the Vmoto E-max range, Sevcon is supplying motor controllers for the 90S, 110S, 120S, 120L (lithium) and also its delivery/courier D models. In each case the Gen 4 is used to control the 48 V, 4 kW maximum power delivered by the bike's silicon battery to a specially developed PMAC wheel hub motor. In all applications the ability of the Sevcon controllers to be closely characterized with the specific PMAC motors used by the scooters contributes to smooth power transmission, improved efficiency and an extended range capability. The ultra compact size 2 Gen 4 controllers being used by Vmoto E-max incorporate the latest in electronic motor control technology and enclosure assembly to provide the smallest controllers in the industry relative to power delivery. This enables the controllers to be integrated into very tight engine compartments and body spaces without sacrificing scooter performance.
