The first motor we are going to release is the 265 mm version. This one will have the following specs:
- 5500 RPM
- 265 mm motor diameter
- 86 mm motor length
- Peak power: 300 kW
- Nominal power: 150 kW
- Peak Torque: 521 Nm
- Nominal Torque: 250
- Efficiency at nominal power: 91%, Peak eff. 98%
- Dry mass: 22,5 kg
- Cooling: water
So this gives a power density of 6,7 (nominal) and 13,3 (peak).
Oh my. I can think of several cool applications for such a beast.
Still trying to fully grasp what sets this type of motor apart from bldc, induction, pm etc. If them claims are not drunken ramblings clearly they are doing something right. Is that the case for most axial flux motors or their take in particular? Meaning does other makers of this type of motors come close to them numbers? What about manufacturing costs and production costs of this motor vs other electrical motors? More or less money put into raw material, machining and labor costs for this type of motors?
Can the power & weight be any where near true numbers? No numbers left out, or maybe a DOT sign was forgotten?
The 75-7 is about the same weight with about 75 kw peak output if tweaked well on dyno with some effort on the controller. This Magnax motor, larger diameter, about same case length and close to equal weight as the 75-7 motor output peak power 4 times greater, with insane 3 times the torque. And the efficiencies are high too, well i guess they better as the other numbers are so high.
Is there anything remotely true to these numbers?
If so, what makes the Magnax motor so great? I mean huge power in a rather small package with feather weight vs power output.
