The diameter of the motor is by about 2 mm smaller compared to conventional motor. Without an offset the motor will appear to be 1 mm above the plate. The holes are offset such that you have motor's downside exactly at the same position as any conventional motor. The upper side of the motor is 2 mm lower and the CG (shaft) is again 1 mm lower.

Considering that chassis manufactures make a big deal out of lowering a piece of carbon fibre by 0.5mm... these SMC motors have a massive influence on the CG of the car in comparison. Besides the now obvious lower mounting, you can see from the pics that the mass of the stator will move inboard. Plus the motor is much lighter so again you gain in all areas chassis performance. I'm putting a SMC Lowrider in my Awesomatix to build the ultimate CG/polar moment car.

Smc lowriders really lower the CG, but will it be legal for long ? It looks like a 380 can with lots of glue around it....

DavidNERODease

No glue, just superior design.

I though this as its meant to be 540 can but just a quick look in brca rules did not see can size as a rule
plz post if I missed it in the rule book as aid only a quick look

DavidNERODease

It is 540, just doesn't have a "can".

DavidNERODease

Lowrider is ROAR and BRCA approved.

I was under the impression that all the motors had to have a 36+mm can or outside dimensions of sorts... Yeah I guess it's ok for racers to run their motors without a can, just as long as it is glued together properly...I put CA on my aluminum motor screws to prevent stator shorts, is that legal or can I legally just glue the can together without any screws at all ??? What about plastic, carbon or tungsten rotor shafts ??? Rotors are the only parts we really need from the motor; all the other parts are 'optional' and subject to removal, right...Would a wireless stator be legal under the current rules ??? I guess it is legal when X company does it, regardless of the written rules....
I know we're still a few decades away from motorless propulsion, but come on guys, this motor should be the next 'catch of the month'.....lol ....

How about you actually read the rules? They're available online.

Thank you for the clarification. That's bloody trick. Kudos to SMC for that....

... and i'm tempted, I have to say. That LCG stuff will have a LOT more influence than any hypothetical 0.1% extra HP...

thank you

I agree with you. I have been using SMC for the last 6 months and I am very happy with it.
As for the CG is even better - the motor is 10-15 g lighter than a conventional motor. So if you don't change anything else on the car but the motor, you will have to balance the chassis. You put the balancing weights as low as possible (on the chassis and under the motor CG). The overall effect will be even lower CG of the overall mass related to the motor than what the offset holes suggest.

I see a lot of people selling off their R1 21.5T V21 motors. What's the new hot motor currently trending now?

I think they may be selling off their V21's because the BRCA outlawed them and people are thinking that ROAR may follow.
