#### Allex

##### 100 MW

Sorry could not find a thread about this motor so created a new one.

I think that this new mxus 3000 motor could be a serious competitor to the Crystalyte 40xx series. People call it Mini Cro

-------------------------------------------------------

Just look at the spec for V1

Nominal: 3000W

Peak: 6500w

Stator/Magnets with: 45mm

4 turn

Stamped steel stator

0.5mm Laminations

Weight: 8Kg Stamped steel stator(8.3Kg with aluminium stator)

135mm dropouts

13AWG phase wires

v2 differences compared to v1:

4Tx16 windings;

Al stator base;

0,35mm laminations;

+300g to weight resulting in 10kg total for motor laced in 26" P35D meety rim with 10G spokes.

Here is some more Hard data for the EE folks:

MXUS XF40-45H (3000W) DD Hub motors...

21X3T Winding

Phase resistance = 0.072 Ohms

RPM at 50.2V = 597, 11.89 Kv

1.78A/89.4 Watts No Load

16X4T Winding

Phase resistance = 0.110 Ohms

RPM at 50.2V = 448.2, 8.93 Kv

1.08A/54.2 Watts No Load

12X5T Winding

Phase resistance = 0.163 Ohms

RPM at 50.2V = 359, 7.15 Kv

0.84A/42.2 Watts No Load

10X6T Winding

Phase resistance = 0.225 Ohms

RPM at 50.2V = 299.4, 5.96 Kv

0.64A/32.1 Watts No Load

All bare hub motors weigh in at right around 9.14 Kg.

These are the motors I sent to Justin for Dyno Testing.

No Load Current was measured with my Fluke 77 iii RMS Digital Multimeter, so it should be pretty darn accurate.

Here is a speedrun with Adaptto 18FET controller (Max-e)

First is with OVS 0, second run is OVS at 7

20S14p LG DBHEII batteries

Same controller settings, same Phase stock wires, 160A/400A so around 13kW. Basically Maximum settings that I can dial in on a Locked max-e

Sorry, just did a fast cut, no fancy stuff here, on top of that youtube does a hard compression so you dont see small figures on the display during a ride.

Oh and, it actually wheelies a bit as seen in the video, I had to apply throttle gradually to keep it down.

24" wheels btw.

MXUS3000 ver.2 tested on steep hill.

E-kross frame. Adaptto Max-E controller, LiNMC 77V16Ah battery. 90A battery current, 180A phase current. 7.1kW max power, 79Wh/km energy consumption.

This motor has a good torque reserve.

And 11kW run at 130Amps ~110km/h

I have measured the diameter of ONE strand of the MXUS 3000 4T from a friend today.

The diameter was 0.0225"

I other words, it's equal to gauge 23.

In that 4T there is 16 of these strands witch is equal to exactly a 11 gauge wire.

In a 3T there is 21 of these strands witch is equal to just a bit bigger than a 10 gauge wire.

The stock wire gauge on the MXUS 3000 is very similar to a 16 or 14 gauge.

It is clear to me that a wire upgrade WOULD improove performance and avoid melting wires and also connectors due to the added wire heat transfer to the connector.

According to Justin's data, Teslanv get the following phase current limits on the various windings:

MXUS XF40-45H "3000W" Direct Drive Hub Motor Series:

3T:

Max. Continuous Phase Current: 55A

Overheat in 10 Minutes: 85A

Overheat in 60 seconds: 242A

4T:

Max. Continuous Phase Current: 42.6A

Overheat in 10 minutes: 66A

Overheat in 60 seconds: 186A

5T:

Max. Continuous Phase Current: 34.9A

Overheat in 10 minutes: 51.6A

Overheat in 60 seconds: 150A

6T:

Max. Continuous Phase Current: 30.3A

Overheat in 10 minutes: 47A

Overheat in 60 seconds: 132A

Generic Winding Phase Current Limits per strand:

Max. Continuous Phase Current: 2.84A per strand

Overheat in 10 minutes: 4.4A per strand

Overheat in 60 seconds: 12.4A per strand

*All data assumes a non-vented hub motor. Venting or other methods of cooling should increase these values.

If these values seem low, just remember that when accelerating from a stop, you might start out at very high phase current, but then in theory phase current would drop as you reach your cruising speed. - As long as your cruising (continuous) phase current is not higher than listed above, you would theoretically never overheat the motor.

And here is the excel spreadsheet teslanv developed so you can calculate and compare unloaded speed and torque, given Motor winding, volts, Phase current and tire size.
