content: Hello People,Its is a kind of Wired Request but I hope to get a helping hand from your side,I am Starting a Small Company in India With very limited resources at my hands right now.My main Vision is to Convert cheap petrol/Diesel based public transport Vehicles with Electric Public Commute.To Keep the cost low I am Developing Electric Motor and Electrical Controls In House.For my initial Steps I Do need to get my motor Control Solution Up and Running to Show Investors and Interested people to Invest in my venture.As You already know that I am Working on my personal Budget Right Now, So The test Equipments that would be required for them are Out Of my reach.I would be very Delight if Some of you would Mentor and Provide the necessary resources to realize the same.Thank you all.

content: buy oscilloscope, DMM soldering iron etc what else? search this forum for "what to buy equipment for beginners", there are plenty of advice in this forum and internet, google is your friend. i'm not in the mood of repeating things. good luck with your venture and india.

content: To me that reads more like a plea for donation, not a request for information as to which scope to buy. On which case this isn't even the right sub-forum.

content: I'm also developing motor controllers on a personal budget, my recommendation is to get a Rigol DS1104Z, great value for money and the 4 channels are a must for troubleshooting 3-phase motor drives.Skickat från min Nexus 6P via Tapatalk

content: Quote from: godfather on February 21, 2016, 07:20:49 amThat is the worst path to follow. Designing and producing motor controllers is not going to be your core business so you will never be able to make them cheaper than buying readily made ones. Investors will also see that. My advice: buy several different motors + motor controllers and make sure you can use several types in your vehicles. This means you do not depend on a single source/single vendor for your business to grow. The same goes for the batteries you'll need.An oscilloscope will be useful but also think about current probes and differential probes to make measurements easier. Getting the electrical system of en EV going will be challenging enough without developing a motor controller from scratch.

content: Quote from: godfather on February 21, 2016, 12:55:33 pmIf you honestly can't afford to buy a DS1104Z then I can't see you being able to develop a high power Inverter driver for electric vehicles when the average single MOSFET / IGBT for an electric bus would be around 600V @ 600-1200A costing about £200-300 each, almost as much as said scope.I would suggest looking into ways to begin developing an initial cashflow.

content: @TCWilliamsonYou are right,But Its Hard to Explain why I am looking for Donation based Test Equipment,Here In India People Don't Believe Quickly new Ideas.So getting Cash Flow on an initial Level is as close to impossible,As I have Already Specified that I am On a Very Tight Budget and I can Only Afford the power Components and Controls Circuits Basic components and PCB But Its Really Hard to get hands on a DSO Right Now,That Is the reason I am asking for help.
