new Siemens 5/1 thrust ratio electric aircraft motor

[Voltron]

For the hybrid min sized airliner market... 50kg, 260kW at 2600 rpm.

Weight saving has come from several directions.
For example, the stator is of cobalt-iron alloy for high magnetisability, and the permanent magnets of the rotor are in a Halbach array – a way of stacking magnets to get all the flux on one side of the stack – so flux is directed with minimal use of material.

2600 RPM. I wonder how many poles?

Very cool. Both liquid and air cooling like the EMRAX. The EMRAX 268 does 200kw peak and weighs 20.3kg

I wonder how much torque it makes

 

[Punx0r]

260 kW @ 2600rpm = 955Nm

Or 19Nm/kg

260kw at 2500rpm continuous. That is impressive

Wonder how much it can make peak. It has cobalt lams so its not ironless besides the magnet backing. Very interesante they choose an inrunner.

Now it's time to put that on a motorcycle!!!

Leftover experimental aerospace motors are going to kick ass...
