🚘 Inspecting curved components is no piece of cake. This is something #automotive manufacturer Aisin China knows a lot about. To address this issue, the company adopted #3Dscanning and #Geomagic #ControlX for their first article inspection and new product development about ten years ago – and it completely transformed its work. ✔ Their team get more detail about a part, faster ✔ They can easily identify part deviations and generate reports ✔ They can innovate quickly Discover more on our blog ⬇  https://lnkd.in/eNydg4Ft

⚡ Current Source: Quick and Easy Design ⚡ Out of the multitudes of ways current sources could be designed and built, the following is an example of a simple implementation with readily available components. ⚡ Parts list: 1.     2N4401 or NPN BJT equivalent 2.     680 Ω, 0.25 W 3.     120 Ω, 0.25 W 4.     DIALCO 558-0201 LED or equivalent 5.     1N4737A Zener diode 6.     +12 V power supply ⚡ The goal of the design is to allow 10 mA through the electronic load and keep it constant over changing loads. ⚡ 1N4737A is a 7.5 V Zener diode and per the datasheet the test current is 34 mA (see attached document). Hence, the voltage drop across Rx must be 12 -7.5 = 4.5 V. For current of 34 mA, Rx (max) is calculated as 132.35 ohm. Conservatively, let’s choose 120 ohms. ⚡ This bias maintains 7.5 V at the base of Q1. The emitter voltage = 7.5 – 0.7 = 6.8 V. ⚡ From the datasheet of DIALCO 558-0201, we observe that the typical forward current and forward voltage drop for the LED is 10 mA and 2.1 V respectively. To get 10 mA through the LED (electronic load), the value of Rset must be: 6.8 V/10 mA = 680 ohms. ⚡ Per the results, it can be seen that the designed value of 10 mA, is maintained constant through the load as long as the voltage drop required across the load is less than 5 V. Beyond this point, the circuit runs out of voltage headroom and the transistor enters saturation from active region. #electronics #circuits #design

The interior permanent magnet synchronous motor (IPMSM) received great reputation nowadays in #electricvehicles #automotiveindustry due to its high torque density. But the challenge hits when the motor operates at high torque due to cross coupling inductance and saturation effect. hence true MTPA trajectory is not followed by control. found a detailed description about the cross coupling magnetic saturation for PMSM which is attached. https://lnkd.in/gwBNstih

The volume and breadth of tests ADAS engineers need to conduct is growing. You need to capture everything that happens during every test, you need to be able to trust that your tests will run smoothly and you need to be confident that your data is accurate enough for whichever test standard you're working to. Central to your test is your source of localisation. Download the new OxTS ADAS Testing Solution Brief and learn more about: 🚘 The key questions to ask yourself before embarking on a project. 🚘 How OxTS and NVIDIA are working together to combine the most advanced automotive AI platform with industry-leading localisation.  🚘 How you can tailor your localisation solution to ensure it's fit for purpose.

Another EMC design review going out of the door shortly. I'm really glad we got to do this one because the design would not have met the Industrial immunity tests in EN 61326-1 Table 2 or EN 61000-6-2. No ground planes or filtering on analogue input for temperature sensing. No surge protection on long signal cables. No AC mains surge suppression. We even did a quick Electrical Safety review and spotted a potentially non-compliant power supply and relay. The only reason we spotted these issues is that we were looking at the models at the customers request to see if there were sufficient common circuit elements to reduce the requirements for testing (there weren't). We couldn't reduce the scope of the testing, but we have hopefully saved them time and money by catching these issues before they become failures. #emc #electricalSafety #DesignReview #ProblemSolving #RightFirstTime

What’s the point in simulating your PCB design if you end up building something different? Simulations are typically used to either develop design rules for placement and routing or verify designs after routing, before fabrication. But if you don’t define a single source of truth in your PCB spec stackup, you may find that your simulations aren't lining up with the reality of what you have actually built. https://sie.ag/7LtrfT #PCBDesign #Simulation #SignalIntegrity

🚨 If you’re still handling ADAS calibrations like this, you’re behind: → Going line by line down an estimate to scan for keywords that might trigger calibrations → Flipping through pages of OEM manuals to tie line item triggers back to recalibration protocols → Manually validating if the appropriate components (sensors, cameras, modules) are even equipped in the car you’re working on. If you’re doing this, I’m 99% sure you’re missing key calibrations. → Entering every line item into Quickbooks by hand because every calibration has varying levels of complexity and requires different labor hours → Expanding your business by offline field sales. AKA going shop by shop to convince them to send you their estimates over email and calibrate their cars After using Revv, shops upgrade their ADAS business in EVERY step ⚙️ → Revv plugs into your estimation software to identify every ADAS calibration from an estimate → Up-to-date links to the latest OEM manuals that explain why and how to perform each calibration → Advanced bookkeeping and auto-quoting, so you can automatically configure prices based on whatever matrix you want – labor hours, make, complexity etc. → Visibility into efficiency around what calibrations were actually performed and why a calibration wasn’t performed so shops can optimize their P&L → Centralizing communication with partner shops through Revv. No more offline field sales / convincing shops to email estimates Ultimately, Revv gives you and your customers a better experience 🤷 It shows that a shop has invested in resources to calibrate a car properly, and we’ve seen shops (successfully) use Revv as a differentiating factor in their customer acquisition strategy. Everyone wants to work with the shop that actively puts more effort into getting safer vehicles back on the road.

Solving EMI/ EMC issues require a lot of iterations. Can a young team or freelancers solve the problem? Well, it depends on the engineer's experience. Do you agree? Recently, we tackled redesigning a PCBA for a DC brushed motor's variable speed control system, complete with an LCD interface. Initially, our customer struggled with EMI and EMC compliance, lacking the resources to meet standards. They had a team of young engineers and some freelancers onboard. But the thing is, compliance demands iterative testing and experienced engineers to address root causes effectively. None of them had on their team. Although less expensive, pre-compliance testing requires a well-equipped lab for multiple iterations. Here's where we made the difference. Our systematic approach ensured the new version met and exceeded compliance requirements, resulting in a more robust and reliable product. With 70+ engineers, we are committed to achieving the best results in electronic systems. What challenges have you faced with EMI/EMC compliance?
