E-scooters turn to Sevcon Gen4 controllers

Monday, May 9, 2011

With growing worldwide demand for electric scooters, one of the world's leading brands has specified new advanced technology motor scooters from Sevcon that combine compact size with high power capacity.

Vmoto E-max, a publically listed Australian company with its Euroepan head office in Barcelona and distributors around the world, has turned to new Gen4 digital controllers from Sevcon. These meet the specific performance needs of various 50cc and 125cc equivalent electric scooters that utilise 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 Gen4 is used to control the 48V, 4KW 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 characterised 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 Gen4 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.

新的控制器完全可以open compliant, enabling simple and flesible software integration with vehicle drive and control system components through a series of input and output connections. In addition, this ability also allows full integration with vehicle diagnostics and dashboard displays of speed, battery status and other scooter controls. Size 2 Gen4 controllers are available in the form of three individual new products with nominal battery voltages of 24-36 VDC, 36-48 VDC and 72-96 VDC and peak currents of 275A (for the 24V and 48V versions) and 180A.
