1688

Item 1688

DESIGN: AeroVantage ~ Motor - Full-size - UQM - PowerPhase

Motors:

They are water-cooled. Could the hub's cone be the radiator?

This one looks good for light UniCopter, assuming that the housing can be rotated re cooling etc.; http://www.uqm.com/products/specsheets/PowerPhase75.pdf. Perhaps it might be an idea to use 2 of these.

This one looks interesting if the intention is to go for the maximum weight of 600kg (1,320lb), assuming that the housing can be rotated re cooling etc http://www.uqm.com/products/specsheets/PowerPhase100.pdf

Controller:

CD40-400L Brushless Permanent Magnet Motor Controller It is water-cooled. Have hard copy.

The weight is 35 lb.

Notes:

Maximum speed of PowerPhase 75 motor is 8,000 and the maximum efficiency is 94% at 5,000 RPM and 120 Nm [88.5 lbf-ft] of torque. Maximum [peak] power is 100 hp. The continuous power is 60 hp.

Maximum speed of the motor PowerPhase 125 is 8,000 and the maximum efficiency is 94% at 4,5000 RPM and 125 Nm [82 lbf-ft] of torque. Maximum [peak] power is 167 hp. The continuous power is 60 hp.

Maximum speed of HiTor Traction System motor is 5,000 and the maximum efficiency is 90.0%. Maximum power is 67 hp. The continuous power is 40 hp. However it delivers its maximum torque at 1,000 RPM and the 2 rotor speeds are 1,200 and 1,500 RPM. This motor will not deliver the same power as the PowerPhase 75 and 125 but there will be no need for the planetary reduction (less weight, power-train friction, lubrication etc) BUT, how is access to the nose cone achieved? It's torque is 100 Nm at 4,800 RPM and 0 Nm at 6,000 RPM.

Which one???
