Does anybody know why DC Permanent magnet motors have constant torque and then drop down torque for high speeds.
Is it due to PWM??
On the other hand conventional motors just show a drop down torque/current defined by no-load and full load points.
I am working on 5 speed AMT shifting strategy.Do you think that the transmission should shift the gear at a vehicle speed where the driver can feel the maximum forward acceleration in each gear( ie max torque at the wheels). If not then what should be the best shift points both from performance...
Dear all transmission experts
Where do you see the emerging gearboxes like DSG,AMT,CVT , conventional Manual and Auto in the next five years for passenger cars.
Who will be leading the market and why?
What are the factors that are controlling this?
Does anyone know which one is more...

What are the industry standard softwares for crank/valve train modelling for automotive engines?
Has anybody evaluated these tools?
What are the limitations on these??
Hi
I need to calculate the wheel slip torque of the transaxle powertrain vehicle.This will be used to calculate engine mount torque reaction under wheel slip condition.Any ideas???
I am involved in concept stage designing of a chassis/frame structure for an SUV vehicle. What are the typical attributes required in the initial stage of desgn. My understanding is that the basic chassis/frame structure should have enough static(torsional and bending) stiffness and dynamic...
