“I’m testing these motor flying Inverters on this motor flying aircraft”
Motors, inverters, and energy methods for electrical plane have strict necessities for weight, effectivity, and security. For that reason, these motors are pushing expertise, going to larger voltages, excessive part counts, and distinctive topologies for each the motors and inverters. Many of those selections have electrical and mechanical results that have an effect on the whole plane. These evolutions in motor expertise require important quantities of testing from prototype to set up, and finally certification. A major quantity of this testing is just not solely on the parts however entails testing the whole plane electrical community for system stability and certification.
On this webinar on the Fall Digital Convention on EV Engineering, offered by HBK, we’ll overview new exams for evaluating these motors and energy methods:
- Copper chook testing & flight cycles
- Excessive part depend analysis
- Failure testing
- Excessive basic testing
- Electromechanical analysis
- Structural results of electrical motors
- Excessive voltage measurements
Different classes at our Fall Digital Convention embody:
Managing Warmth Via E-Fluids
New thermal administration driveline e-fluids, designed to allow the newest electrified powertrains and batteries to carry out at their best, have been developed for the newest electrical automobile {hardware}.
For instance, many earlier electrical automobile powertrains had been developed utilizing computerized transmission fluids (ATF). Not optimised for EVs or their thermal administration, these are being outdated by the newest era of lubricant fluid expertise, termed driveline “e-fluids”. e-Fluids are optimized for automotive electrified {hardware} varieties, comparable to the newest era of e-axles, and funky and defend such units far more successfully.
Lubricants at the moment are anticipated to be in direct contact with powered motor windings and uncovered and electrically insulated electrical parts. Traits comparable to the flexibility to chill electrically energized surfaces along with different surfaces that may develop into sizzling in addition to the safety of uncovered electrics are of elevated significance.
Motor effectivity will increase with diminished fluid churning losses and appropriate cooling. It may be additional improved utilizing optimised fluids which offer thermal administration. Guaranteeing appropriate put on efficiency as required by the {hardware} engineers is of important significance to guard the gears and bearings, and is a necessary profit supplied by the e-fluids.
The most recent sorts of additive parts utilized in e-fluids have developed considerably over conventional varieties, and a brand new class will probably be described within the webinar. That is the newest sort of powertrain e-fluid expertise to enter the market, which has no corrosive lively sulfur additive current, typically termed “sulfur-free”.
The e-fluid is an engineered part and varieties a part of the general design of the electrified {hardware}. The presentation will cowl the basics of the newest e-fluid design, fluid properties, and the way a thermal administration e-fluid is greatest evaluated for efficiency.
This presentation will probably be of curiosity to engineers and fluid formulators searching for an introduction the fundamental ideas behind fluid thermal design. As well as, the newest fluid testing strategies to deal with among the {hardware} challenges, resolved by the fluid, will probably be described with the purpose of enabling the engineer to make the most effective thermal administration fluid alternative for his or her newest {hardware} designs.
