“I’m testing these motor flying Inverters on this motor flying aircraft”
Motors, inverters, and energy techniques for electrical plane have strict necessities for weight, effectivity, and security. For that reason, these motors are pushing know-how, going to larger voltages, excessive part counts, and distinctive topologies for each the motors and inverters. Many of those choices have electrical and mechanical results that have an effect on the whole plane. These evolutions in motor know-how require vital quantities of testing from prototype to set up, and in the end certification. A big 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, introduced by HBK, we are going to assessment new exams for evaluating these motors and energy techniques:
- Copper hen 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 embrace:
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 possible, have been developed for the newest electrical car {hardware}.
For instance, many earlier electrical car powertrains had been developed utilizing automated transmission fluids (ATF). Not optimised for EVs or their thermal administration, these are being outdated by the newest technology of lubricant fluid know-how, termed driveline “e-fluids”. e-Fluids are optimized for automotive electrified {hardware} varieties, resembling the newest technology of e-axles, and funky and defend such units rather 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 resembling the power to chill electrically energized surfaces along with different surfaces that may change into sizzling in addition to the safety of uncovered electrics are of elevated significance.
Motor effectivity will increase with decreased 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 significant significance to guard the gears and bearings, and is a vital profit supplied by the e-fluids.
The most recent kinds of additive parts utilized in e-fluids have advanced considerably over conventional varieties, and a brand new class shall be described within the webinar. That is the newest sort of powertrain e-fluid know-how to enter the market, which has no corrosive lively sulfur additive current, generally termed “sulfur-free”.
The e-fluid is an engineered element and types 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 finest evaluated for efficiency.
This presentation shall be of curiosity to engineers and fluid formulators searching for an introduction the essential rules behind fluid thermal design. As well as, the newest fluid testing strategies to handle a few of the {hardware} challenges, resolved by the fluid, shall be described with the goal of enabling the engineer to make one of the best thermal administration fluid alternative for his or her newest {hardware} designs.
