In recent years, car manufacturers have announced a new plan to electric transformation. However, in addition to replace the fuel engine to a motor, there are many important things that need to be completed. Interestingly, as a small start-up business, H3X hopes to fully integrate the motor to achieve the performance goals that are far better than all competitions on the current market.
It is reported that, Jason Sylvestre H3X CEO, Max Liben, chief technology officer and chief operating officer Eric Maciolek, is met when participating in electric car manufacturing and racing at the university. After the high-tech and automotive industries (including Tesla) has accumulated years of experience, they are once again in order to improve the power density of the motor and came together. Electric vehicles, electric vehicles, power performance, whether or still in the early stages of validation are a major obstacle to their influence reality.
For the unmanned aerial vehicle, a few kilowatt-hour battery is essential. In addition, in the light equipment, also a small amount of an appropriate EV battery. Unfortunately, in the load, energy density, and battery size, etc., is currently difficult to achieve a better balance, unless the motor performance also ushered in a huge leap, this is the direction H3X the effort. Are already part of our design solutions will enhance the per kilogram power to weight ratio of about 10 to 20%, but H3X claims that its motor is expected to reach 3 times the performance of competitors.
To achieve this, usually by means of integration achieved higher density on the part. In some respects, these parts are somewhat similar to the current motor and electrical assembly. Typically, the power system of the motor itself divided into three parts, drive system, and the speed change mechanism, and they have their own housing, so as to be detachable and sold independently of one another. Impact "Big Three" a major obstacle to integration, is the temperature. For example parts of the transmission mechanism and the cooling liquid may not run at the operating temperature of the motor or the power system, and vice versa.
But H3X research team chose a road basically starting from scratch, in order to achieve the minimum energy efficiency and maximize volume. Specifically, they simply do not like the inverter box assembly are integrated into the motor housing. They are developing, it is a truly integrated design, but the same power level of competing products are unique. Some improved quite significantly (up to 50%), while others may be less (10-20%), taking into account the risk control technology. For example a recent change, is that the power open hardware may operate at higher temperatures and higher loads. While improving performance, but also take advantage of the shared-type cooling infrastructure-based 3D printing.
Shared infrastructure is manufactured by a novel copper 3D printing technology, such H3X various customized to adapt internal geometry, greater deployment of the cooling apparatus within the housing. H3X motor can be simultaneously, and the shift actuator are mounted to the optimum position, without worrying about the position of a conventional bolt-fixing method.
The end result is H3X introduced the first in-one motor prototype - HPDM-250. Not only compact size, power to weight ratio (13) is also far more than competitors. Coincidentally, this also happens to be higher than the theoretical value of the power density of the medium-sized aircraft.
