Why AC motors?
Today almost all manufacturers use BLDC (brushless direct-current motors) in hybrid vehicles and EV-s, because theoretically they are more efficient than their AC (alternating current) counterparts, but technologies develop and thanks to ETDC it is possible nowadays to design and manufacture AC motor that is as efficient as BLDC. This opportunity opens up a whole new future for electric transport, as there will be no more problems connected with using BLDC motors, such as:
- Permanent neodymium magnets comprise all rotors in BLDC motors, these magnets are:
a. Notorious for recycling, not only that, but they also can not be disposed off easily, you can not just throw them in the garbage without consequences since they are detrimental for the environment.
b. Very costly and labor-intensive to produce, to mount into the engine.
c. Comprised of materials, mined in poor countries, that use slaves to mine them etc.
- BLDC motors are more expensive due to more complex construction processes needed to manufacture them.
- BLDC motors bleed power to maintain their rotation speed (since we cannot switch off magnetic field in permanent magnets, motor with such magnets in its construction always needs power to rotate, when power is cut off completely, it exerts huge braking torque stopping itself from rotating, and the greater the speed – the higher the electricity consumption just for maintaining speed of rotation, that effect is very harmful for any electric vehicle, since it significantly reduces range.
- Any debris that enters a motor will be stuck there and accumulating on permanently magnetic parts.
IBC ETDC uses only AC motors in its motors. As opposed to BLDC motors AC motors are 100% recyclable, have 100% free rotating capability at all times, very cheap to manufacture and a lot more robust, since any magnetic dust particles that enter AC motor do not interfere with any of its parts.
