What should the temperature of the traction motors be during work?
Should they be cold, warm or hot?

I've run full throttle one machine today on the stands for fifteen minutes and drove it for another five and the motors got hot. You could put your hand on them but the were pretty hot.

I've measured the current consumption on stands and it was 8-9 A on both motors.
Driving full throttle gave 14-15 A.

What do you think? Is this Okay?
