hello, I am preparing a project and walk to choose a PMSM electric motor.
even so I found these:





ENSTROJ Emrax 2 brushless 30kW 50kW - 200V dc / 75kW - 300V dc 150N.m 200V DC / 250 Nm 300V DC 2000rpm / 3000rpm ar 11kg ip56 http://www.glider-one.si/
dubious this ...


UQM Hitor Brushless PM Motor/Generator 30kW 50kW 180Nm 6500rpm liquido glycol 41kg enviei mail - $20,690 http://www.uqm.com/pdfs/HiTor 10.13.08.pdf
very good but.. $20.000!


LMC LEM 200 -D135RAGS PMSM 18kW 29.04kW 42Nm 40rpm/V 11kg mandei mail aprox 1300euros + 525 controlador http://www.lmcltd.net/

perm motor PMS 156 PMSM 9,5 kW 30 kW 80 Nm 1500 min-1 to 6000 min-1 liquido 31 kg enviei mail http://www.perm-motor.de/site/en/produc ... &linkid2=1

Lemco's are Brushed PM DC motors

 

[nunocabral]

have absolute certainty? :s

 

[frodus]

I wouldn't have said "Lemco's are Brushed PM DC motors " if I wasn't certain.

If you even read their website you linked to, it says right on their homepage:

"..... low voltage high torque permanent magnet DC motors and generators ......"

Those ESTROJ motors look like the real deal. Almost too good to be true. Their figures add up. 50kW peak at 3000RPM, 91 - 94% efficiency, 11kg, small enough to fit inside a wheel or bell housing.

The EMRRAD2 motor is 900 euros. Bargain!

numbers seems - way off ... five times too good
11kg - 150 nm const /2000rpm; 50 kw/3000rpm ???
weird...

2000RPM = ~210rad/s

210 * 150 = 31,600W

Please consider that they say "for 10 Minutes". This is no S1 power spec!

2000RPM = ~210rad/s

210 * 150 = 31,600W
