Default Lynch Motor Company

Hello,

I was wondering what the general consensus was regarding the quality of Lynch Motors. Currently, I am getting ready to set up a dual drive system and I was going to use two LEM 200-D135 RAG/S motors. I just wanted to see if anyone had words of warning against them.

THANKS!!

Hi Dan,

Those are expensive motors!

http://www.cloudelectric.com/product...m-200-d135.htm

Anyway, two of them, for a full size electric car? I would worry about enough power, and torque. And durability. I recommend you go with a good wound field motor for anything bigger than a 2 wheeler.

Regards,

major

2300 is expensive??? in comparison to what? I initially wanted 3P AC motors but those run 2-4 times in price. In addition they are approximately 25lbs a piece, in comparision to the 120-200 lbs for a comparable motor.

As for torque and HP, are you just reading those values off of the cloud electric site? The manufacturer offers specs at various voltages including 110V. In this case, the cont. HP is 18kW which for two motors is 36kW (quite good) I believe.


Perhaps I misunderstood you however.

Hi Dan,

$2300 times 2 = $4600. A bit more than a 9 inch series motor and a lot less for your money, in my opinion. Take it for what it's worth. You asked.

Pretty much.

Has anyone else used these motors in the size vehicle you are considering? Like I said, you asked. I just don't think you'll be pleased (for long) with these motors in a car conversion. Specs don't tell the whole story. Maybe others will chime in with experience or opinions.

Regards,

major

Are you thinking about something like a D&D ES 31B? I guess if you could give me a better motor (comparable weight 25lbs; comparable power atl east 15kW continuous) i would agree. I just havent found one that performs as well on power, and in the long run i am more concerned about power as this is for a high performance application. Granted I am not willing to spend cash on 10K BRUSA motors but I am not going to skimp on cash if its worth it.

here is a bike that uses two smaller versions of this motor going 92mph.

Thanks for the commentary Major, I really appreciate the discussion and need opposing opinions for a reality check....so thanks and keep up the discussion.

And here is what you can do with a couple of 6.6 inch wound field motors.

Werent those modified motors. And at the end of the run, they were a giant 120lb anchors.

Well Dan,

What racer won't modify his equipment? And from what I've seen, mods were not drastic. A little more advance. A couple of Nomex pieces. But, they were about half the cost of your choice to start. And I doubt near 100 lbs each. And, boat anchors? Not quite. In need of some TLC, perhaps. He is still running the same motors today, I think. And going faster.

From you original post. I don't know your application, or skill level, but you have my words of warning. Take it or leave it.

Regards,

major

You have only made suggestions regarding personal preference. I would really like to hear someone who has actually used them.

And the Killacycle was only so fast because it had a dedicated power source that could deliver 1850 amps. Unlike my example which was capped at 400A. At those currents, anything that survives will go fast.

Hi, I use Cedric Lynch's current production motors in motorcycles, and have to say they are about the most efficient motors out there.
I notice most car users are using similar controllers to me, a pair of Agnimotors can easily take full power from a Kelly 120v1200A, or in series from a 144v650A. Since the controller is the limiting factor, why not use a pair of Lynch/Agnimotors? I reckon that with the weight advantage the car will go better than with a 60KG series motor!
