KLD says that their new motor features a substantial shift in electric motor design, one that overcomes motor inefficiencies and EV drawbacks (which other manufacturers try to overcome via battery technologies).

The motor system used by KLD is made from a composite material that generates significantly less heat. And less heat means greater efficiency. They use an innovative nano-crystalline composite material, so that the motor conducts energy ten times more efficiently than traditional iron-core motors, eliminating the need for additional cooling mechanisms. In addition, of course,   it gives greater responsiveness. With its high frequency to low RPM ratio, the KLD motor does not need a transmission. And  it uses standard batteries.

The cost of a scooter with a KLD motor system in the Vietnamese market is $1500 to $2000, or about what a run of the mill EV scooter costs here in the U.S. KLD says that by increasing the production run, the economies of scale should bring the costs even lower for large markets.

KLD is working with Sufat, the leading Vietnamese-based scooter manufacturer, to develop a new line of scooters designed to integrate electric motor system.

Vietnam has over 22 million scooters on the road, which is a huge number of a place the size of New Mexico, so they know scooters!
