Tesi bench checks.
As voltage, during rests, should be approximately constant, the starring motor shall be energized l:-y large
capacity batteries.
The specified voltages, applied to the motor terminals, shall determine the prescribed current drains,
through the setting of a rheostat. No result would be reliable if such conditions were disregarded, with
the exception of the torque reading, and only approximately.
To verify The motor performance check the electrical and mechanical specifications as follows.
