Parts and service very widely available too. I think they also get used as drilling motors.

- sitkack 4y agoThis blows my mind, that there exists this standard high horsepower generic motor used in a ton of applications. I am going to start seeing the D-77 everywhere. https://en.wikipedia.org/wiki/Traction_motor#Power_control https://en.wikipedia.org/wiki/Traction_motor#Power_control I like how they use a bank of resistors as the transmission, but they are just dumping the difference in heat. Has an electropunk quality to it. I wonder if you could use a retroencabulator to control an A77, they are AC afterall. OMG, 11k NM of torque. It weighs 2500 kg! You could power one with an electric car battery, probably 2-4 to reach full 350kW. Could you imagine a robot arm made out of these as servo motors? http://www.americantraction.com/download/360 http://www.americantraction.com/download/360 (warning this will download a pdf)
