Thanks for your ideas.
I appreciate the driveline calcs for vehicle speed and so on but don't fear - you're all right in your points but nonetheless I want to be able to rotate the output of the driveshaft through 90 degrees without excessive losses / efficiency degradation.
Does anyone know a...
Thanks Waross,
I tend to agree, the torque target is more probably more sensibly met by gearing.
I would have no problem using a two speed epicylic.
Whats the gist if I use 3000/8000 instead then?
Also, Mike H - what other options are you thinking of?
Hi, I'm trying to find out if anyone has ever found a drive coupling able to handle high levels of power (>100kW) at speeds up to 7-8000rpm while able to articulate from 0 degrees up to 90 degrees.
I thought about a bevel coupling with input and outputs picking up off a joint bevel gear but...
Thanks Gunnar,
The motor would be constant power from 1500rpm out to 8000.
Hence torque at 8000rpm is 150Nm.
I tend to agree on the PM solution yep.
The performance target for power (125kW) is certainly continuous at 8000rpm. In reality the 1500rpm torque would probably have to be sustained...
Hi,
I'm trying to find out what constitutes absolute minimum volume and mass for a 125kW motor to drive a propulsion propellor at 8000rpm. Maximum torque of 750Nm at 1500rpm or so.
Preference is for minimum frontal area ie. motor diameter with length less an issue:
<350mm ideal
<450mm...

I'm making a vehicle chassis in Aluminium honeycomb panels -ie. a lightweight vehicle. I need to meet strict EMC targets for conducted and radiated emissions - ie. shielding and filters all over the place etc.
As I'm not the electrical chap I was hoping you might be able to indicate what I...
