EMI2.1
ne 1 geliefert wird, vom Stillstandsmoment MSt läuft der zu prüfende Motor an. Bei Unterschreitung des Hochlaufmomentes-MH bei der Drehzahl nH1 steigert sich die Drehzahl des Prüflings infolge des freien Momentes MFrasch auf den Wert non, wobei der Wert des Belastungsmomentes infolge der automatischen Drehmomentkonstanthaltung unverändert bleibt. Dieser Wert entspricht dem Hochlaufmoment MH und ist an der Drehmomentenwaage der Pendelmaschine 1 ablesbar. während die Werte n-undn,j für die Dreh-
EMI2.2
MK wirdder Pendelmaschine l ablesbar ist, hiebei wiederum konstant gehalten.
Die zugehörigen Drehzahlen nK1 und nK2 können dabei am Drehzahlmesser, der vorzugsweise an der Pendelmaschine angebracht ist, abgelesen werden.
Da bei der erfindungsgemässen Einrichtung zur Bestimmung des Hochlauf-und des Kippmomentes des zu prüfenden Asynchronmotors nur diese beiden Werte des Drehmomentes abgelesen werden müssen, ist ihre Ermittlung sehr rasch möglich.
Die erfindungsgemässe Einrichtung kann selbstverständlich auch für Kraftmaschinenprüfstände verwendet werden. Die Verwendung für Getriebeprüfung, Generatorprüfung u. dgl. ist gleichfalls möglich.
PATENTANSPRÜCHE :
1. Einrichtung zur Aufnahme des Hochlauf-und des Kippmomentes eines Asynchronmotors unter Verwendung einer Pendelmaschine und eines Drehzahlmessers, dadurch gekennzeichnet, dass zur Konstanthaltung des einstellbaren Drehmomentes der Pendelmaschine (1), die mit konstanter Erregung versehen ist, ein automatischer Stromregler (5) vorgesehen ist.

EMI2.1
ne 1 is supplied, the motor to be tested starts up from the standstill torque MSt. If the run-up torque-MH is undershot at the speed nH1, the speed of the test object increases rapidly to the value non as a result of the free torque MF, whereby the value of the load torque remains unchanged due to the automatic constant torque maintenance. This value corresponds to the run-up torque MH and can be read on the torque balance of the pendulum machine 1. while the values n- and n, j for the rotary
EMI2.2
MK is readable from the pendulum machine 1, again kept constant.
The associated speeds nK1 and nK2 can be read on the tachometer, which is preferably attached to the pendulum machine.
Since in the device according to the invention for determining the run-up and breakdown torque of the asynchronous motor to be tested only these two values of the torque have to be read off, they can be determined very quickly.
The device according to the invention can of course also be used for engine test stands. Use for gear testing, generator testing, etc. Like. Is also possible.
PATENT CLAIMS:
1. Device for recording the run-up and breakdown torque of an asynchronous motor using a pendulum machine and a tachometer, characterized in that an automatic current regulator (5) is provided to keep the adjustable torque constant of the pendulum machine (1), which is provided with constant excitation is.
