MFA - MF enclosed D.C. motors

Transcription

1 MFA - MF example : Data : at 950 min -, - speed drive output voltage 80 V, - supply by thyristor. Operating mode : - reselect the size of the motor using the chart opposite : MFA In the selection table look for the power closest to 0.7 for a form factor of.6 (due to the type of speed drive) (see the following page, an extract of which appears below) : = 0.75 at 2000 min -. How can the rated speed be adjusted to the required speed? By adjusting the armature voltage (speed drive output), without exceeding the rated value, as the power is corrected proportionally. In this case, to be used at 850 min -, the motor will be supplied at = 75.5 V, and = 0.75, or Motor selected : MFA 80 L - 80 V IC MF 2 MF MFA MFA 63 MFA 56 ower min - Speed n M N I η MFA for armature voltage 80 V without excit. size min - N.m A L S S L L L L VL B2.4
