On motors with integral fans, cooling is determined by the
shaft speed, as the integral fan is connected to the motor
shaft. When used in conjunction with the 8200 motec
frequency inverter, the motors can travel through a variable
speed or frequency range. If the output frequency of the
8200 motec is low, the air flow of the integral fan is not
sufficient to dissipate the heat loss occurring in the motor
at the rated torque (M N ). Therefore, the torque (M) that can
be drawn from the motor should be reduced to less than
20 Hz. The following dependence applies to the various
motor frame sizes:
Note: You should also refer to the technical data and ratings for the 8200 motec frequency inverters
(see page 4-12 ff.).
