E-bike with dynamic power management electric motor

电动自行车是所有形式的城市道路交通工具中个人效用和环境性能的最佳平衡之一。这项研究将有助于促进电动自行车的采用，并量化电动自行车如何最恰当地使用，以及如何减少加拿大城市中心的排放可以受益，并将更好地定位Exro利用其先进的电动马达利用不断增长的电动自行车市场。Exro的电动马达基于一种新的专利控制技术，该技术显示出在广泛的运行速度范围内实现更高效率的巨大潜力。电机采用Dynamic PowerMangementTM(DPM)技术，可以感知电机负载的变化，并在电机内多个绕组的并联或串联布置之间进行动态切换，从而在很大范围内实现最佳效率。该项目将在电动自行车上采用和实施这项技术，并评估其在代表各种城市环境实际使用的各种驾驶周期中的性能，包括个人通勤和拖车。电动自行车需要在速度和扭矩上与电动传动系有相当大的差异，而Exro的DPM技术提供了显著提高性能的潜力。拟议的研究将对这项技术进行系统评估，并确定电动自行车商业应用所需的关键开发。

E-bikes represent one of the best balances of personal utility and environmental performance of all forms ofurban road transport. This research will help promote the adoption of e-bikes and quantify how e-bikes can bemost appropriately used and to reduce emissions in Canada's urban centres can benefit, and will better positionExro to capitalize on the growing e-bike market using its advanced electric motor.Exro's electric motor is based on a new and patented control technology that shows great potential in achievinghigher efficiency over a wide range of operating speeds. The electric motor uses Dynamic PowerMangementTM (DPM) technology that senses changes in motor load and switches on the fly between eitherparallel or series arrangements of the multiple windings within the motor to achieve optimal efficiency over awide range. This project will adapt and implement this technology in e-bikes and assess its performance in avariety of driving cycles representative of actual use in various urban environments including personalcommuting and drayage. E-bikes require fairly significant variations in both speed and torque from theirelectric drive-train and Exro's DPM technology offers the potential of significant performance gains. Theproposed study will allow systematic assessment of the technology and identify critical developments requiredfor its commercial adoption in e-bikes.
