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 ???

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
