IEdrives has decades of experience with evaluating, sizing, integrating and using large to small, AC and DC, electric motors in all types of vehicles.
IEdrives has decades of experience with evaluating, sizing, integrating and using large to small, AC and DC, electric motors in all types of vehicles. All of these vehicle motor applications had very aggressive loading conditions on the drive motor, with an additional overlay of large transients being applied. Identical to vehicle traction issues, there were both low speed and low power demands to low speed high power demands, along with all high speed requirements that need to be meet. At all times, the expenditure of electrical energy had to be used wisely and not wastefully, minimizing parasitic energy losses was a primary concern.
IEdrives can provide detailed analysis of your existing drivetrain evaluating its strengths and weaknesses, with a critical consideration of the vehicle’s intended driving cycles. A primarily focus of this initial evaluation is on the performance capabilities, strengths and weaknesses of the selected traction motor and its speed controller. The vehicle’s drivetrain gearing provides an overlay and once selected, immediately defines the vehicles ability to accelerate, overcome wind resistance, rolling resistance, and climb hills (or not) at various speeds. All motors are different, some trade ultimate performance and packaging for much more aggressive pricing…which has its place.
IEdrives can further analyze your company’s vehicle and offer alternative drive train gearing in the presence of a 2 speed, 3 speed or greater gearing choice transmission. IEdrives can provide detailed information on cost, benefits, strengths and weaknesses of each configuration, providing valuable in-house education and in-house product expertise for the next vehicle iteration. A valuable part of these services are the various shifting strategies that your company can implement to better meet the unique needs of your key customers.
Here are graphed examples of a traction motor/drive train analysis which was performed on a production, all-electric vehicle. This type of analysis will provide similar significant insight into your vehicle’s current performance capability; find its strengths and shortcomings. It will also provide competitive insight as to how multiple gearing can be used to dramatically improve your vehicle’s overall efficiency in excess of 30% along with improved driving performance. The second graph illustrates one possible shifting strategy.
