Ekretz Modded CSW V1 comparison to Beta V2

[lemansfanatic]

while we're slightly ot, why does a direct drive (servo) wheel cost more than a belt and pulley or gear wheel anyways? Theres less moving parts so technically it should be cheaper, right?

A lot of the cost difference is the motor. Large, powerful, high quality motors used under their rated power so they don't overheat and lose power are not cheap.

From what I understand, the motor is more expensive because it has to be capable of higher speeds and more load, as there is no change in ratio to bump the speed up.

The motors in direct drive wheels are rated at like 100x torque and well over 10x power of the motors in the various belt driven wheels. And they are massive, effectively industrial devices, not originally intended for home use.

Just to reiterate a bit:

The motor on a direct drive wheel has no gearing to "help" it and instead must rely solely on torque at its shaft. This in turn requires a much larger motor than might be used on a wheel with a belt(s) or gears. Even a "cheap" China made servo motor large enough to be effective would be fairly expensive. Then you need a controller to pair with that motor in order to drive it properly, which is also generally not cheap.

My verdict is the modded base is the way to go if you already have a V1 base.
For the people that do not have a CSW V1 and looking to get a good wheel , I would go for the V2.

Can you link me on the details on how to mod my base?

I am wondering id there are brushless motors for this that fit perfectly. I seen the mention of buelers. I am hoping there another post I missed on brushless. Also whats this about the optical encoder going bad, if you can linkme a fix on that I would love to read it.

I made my own hydraulic hand brake, and shifter out of real car parts which plugs into the base, so I am pretty confident I can do this.

I know this is an old post. I just got my hands on an old csw v1 base and got the universal hub new.
Thanks for your write up so far.

From my understanding you can't really go brushless on the v1 as the electronics that control the motors is vastly different from that of a brushed motor.

So much for hoping. I was doing some research and so far I have come up with this motor, but I am trying to get closer in size.

Stock motor size is Shaft diameter: 3.0 mm case size 37.5 mm x 57 mm.
This one is Shaft diameter 5.0 mm case size 36mm x 67.8mm.

I have still not found the mod where it details that persons experience so I can learn from it. I know I can figure it out on my own, but its always better to see what others have done first to avoid mistakes.

Thanks for your reply.

Or this motor which is closer, but I need to understand better how the sensor works. Its shaft diameter is a perfect match

Neither of those are going to work. Read THIS thread and go from there.
