Revolt new motor RV 160 Pro

Motor looks like a beast! I have the 160 short, I could only imagine the power the full width will produce. Hopefully we see the performance bar raised with these builds.
 
Look forward to see real numbers from those motors. Both regular and short version.
20 kw peak possible?
 
For those who are interested I got the details of the stators of the two 160's from Alexey.

The motors have 14 magnets, 12 slots.
The stator diameter is 151mm.
The laminations are 0.3mm.
The regular version is 45mm stack and the short is 22.5mm stack.
The halls are at 120 degree.
The winding wires are: regular version: 5mm^2, short version: 3mm^2. we can change according to request based on the KV value.
Normally we use delta termination - than the wires after the connection are 10mm^2 for the regular and 6mm^2 for the short.
The output wires are 12mm^2 for both.

The stock motors are 45KV but we can wind to different KV (no extra cost).

I forgot to get the phase-to-phase resistance, but I'll ask. I need some smaller motors for upcoming projects than the 6 phase motors I normally, so I plan to order a couple.

yesterday I tried to connect the motor to my older ebike system for a free spin. It is 20S5P A123 26650 pack, some controller, maybe ~140 Battery amps. 120% throttle. The motor spins. Tomorrow i will try to get tacho for rpm measurement. The controller is slow ramp up cause i don't get brutal torque, no jerk when fast start. It is more like car engine quick to top rpm. I remember on my bike this controller behaved familiar to this, it was smooth, acceleration, you sometimes do wheelies at acceleration even not noticing it is happening. Another thing the motor gets a little warm even in free spin. So there is some losses. Didn't measured the current cause i haven't tool to measure it.
 
Does anyone else notice how small those wires coming out of the motor are? I also wonder what voltage is required to reach 20kW because I don't think pushing huge amounts of amps through those tiny wires is a great idea.

Well, either they take the winding wire gauge out or, if there's a connection, they will most likely step up a gauge, at that point. Either way, I don't think it's something to worry about....
 
interesting. so the short RV160 has the same lams and stack as the MAC geared hub motor, while the MAC has a slightly smaller 135mm dia stator. it will be interesting to compare Km² and no load figures
as the stator is 11% smaller, i'm keen to see if Km will be 11% smaller, too. The MAC is 11% less motor, but has a completely different pole count (36n32p) :shock:

just for comparison: The MAC motor assembly has an axial length of only 40mm, a quite well thought through package
the coil wire is 4x 1.2mm in dia for the 6T. So this is 4*.6²*π= 7.5 mm² at 29.5mOhms phase to phase resistance at the coils, but KV is higher (~62 KV) so this is not directly comparable. I will add more info about this comparison there: https://endless-sphere.com/forums/viewtopic.php?f=30&t=65757&start=200#p1072800

thx for the effort, Karolis. but this is worth nothing without knowing the exact battery voltage during measurement. Do you own two multimeters to measure no load current and battery voltage at the same time? this would be a lot of value.
 
I would really like to know what the torque rating is for the 160 pro. I might try emailing Revolt about it and post whatever they tell me.
 
I was told - "The KT of he 45KV motor is about 30(oz-in/amp)."

I've got one here for testing (53kv), it might take me a couple of weeks to get my dyno set up properly (and dial in the Sevcon controller) but I'll post some results when I can..

At least that adds up. Once we have a value for the phase to phase resistance and a couple of no load amps readings, I'll add it to the spreadsheet.

Hope all's well with you Steve..
 
Hi Miles, all good here thanks, I'm always happy when playing with a dyno, especially when it starts to get cold outside! Hope you're well and happy. We must catch up soon..

Do you want no load current measured motorside or batteryside?

My RCL meter said that phase to phase resistance was 8 Ohms - I tired everything short of banging it on the table but that's the only reading I got! I'll try again tomorrow, that can't be right..
Inductance is 39.7 @ 100kHz.
 
Motor side at WOT for two different speeds. Around nominal speed and half of that would be ideal.

Everything fine here, thanks. Getting closer to actually producing something... :)
 
thanks guys, that info is helpful, i was told by Revolt that they haven't finished the testing and graphs for the new motors yet.

but its a baseline that i can use to get a rough estimate of the power this thing has.
 
It used to be a complete working site. Links to particular pages aren't working right, either. They can't be selling motors like this, that speaks volumes to me. But we'll see.

they're rebuilding by the looks. I dont think its a big crowd, like adaptto in the early days.
 
Anyone got one of these yet? Site has been updated

Operation voltage: 24V-96V
Continuous power/ Peak power: 12KW/ 20KW
Standard KV: 45
Shaft diameter: 20mm
Weight: 8Kg
Price:
With hall sensors: 585USD
Economy Shipping price: 65USD
 
Seems the rebuild removed the sizing of the Rv 160 Pro. If you look at the Rv 160 short they have an image with measurements for the motor. I think there was also one of those for the 160 Pro, but it ain't on the web no more. Anyone got a copy of that image they could post here in the thread?

I can't remember anyone doing a Rv 160 Pro build yet. AFAIK there are only 120, and 160 short builds around.
I wonder who will have the first 160 Pro bike ready? They will surely have 8 kilos of pure fun. :D
