Any interest in big motors after the 8kw sold out? More money, but now bigger and faster. ![Screenshot_20230526_175157_Samsung Internet](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/8/83e7406013f72cc2bcd24b4f825960b47ecb362d.png) ---

Still working out the logistics, but wanted to post the specs. This motor will not only be pushed to an over speed of 9,000rpm, it is rated to 9,300 rpm. Meaning probably 12,000 if the Sevcon could do it. Encoder frequency has a stated limit of 10k rpm, but is that a hard limit? We shall see. ---

Dave, that kind of RPM/speed might be more than the lip seals on the gearbox can handle without an upgrade. Can’t say for certain, but you may even be butting up against the max speed of the bearings. Without knowing the bearing numbers though can’t be sure. ---

Luckily Sevcon maxes out at 10k. Figured that Grant wouldn’t be scared of blowing something up. 9300 is enough for me. ---

Ouch, shipping from France is as much as I paid for the 8kw motors. Only 8 pcs of 15kw available. Preorders @ cost $1,367.31 Discount buying all 8 pays for shipping. **"15KW ASYNCHRONOUS MOTOR FOR ELECTRIC VEHICLE PROMOTION** **1,275 Euro =** **1,367.31 US Dollar"** ---

Those are to help the children who assemble them move them between assembly stations. 😉 ---

> [@AssyRequired](#): > > was going to ask about the weight until I saw those lifting eyes attached at the top. Oh my, L god , 94.5 lb. More than the cast iron 8kw motors. No wonder it was $350 to ship one by sea. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/e/e0e9f21c629a4343f823c42dc80ff6a7d452dbcc.jpeg) ---

I believe customs are taken care of and pallet should ship soon. If tariffs don’t kill me price is still at cost $1,367.31. ---

Got word that motors have shipped. Not without paying another $750 shipping. So that adds $100 per motor. Maybe not such a good idea. 🙂 [Next page](https://community.electricforum.com/t/replacement-for-8kw-motor-kits-15kw/26456.md?page=2)
