More than watt rank, the increase of energy regenerative system cost is caused, and energy regenerative motor also can not carry out energy regenerating in high efficient district.
2）Shock absorber size and weight are significantly increased.Shock absorber with current orthodox car is compared, either using straight line
The electromagnetic damper of motor, or using the electromagnetic damper scheme of electric rotating machine formula, to reach identical damping capacity（I.e.
It is more than 1000W ranks）, shock absorber weight and size are significantly increased, and can not also realize miniaturization and light weight in a short time
Change, this brings new problem to arrangement and energy-conservation.
3）Reliability and poor durability.Using the electromagnetic damper scheme of electric rotating machine formula, also exist because frictional force is brought
Energy regenerative efficiency it is low, the problems such as inertia mass is big and bears the reliability and poor durability of Long-term Vibration impact.
