6-8x curentul nominal
Direct delta start draws 6-8x nominal current — damages motor and fuses
Pornire directa in D = curent de 6-8x nominal — distruge motorul si sigurantele
5-15 secunde comuta in D
Y-D reduces starting current to ~33% — protects motor and supply
Y-D reduce curentul de pornire la ~33% — protejeaza motorul si reteaua
230V D = retea 230V → conectezi in Dreieck (triunghi)
230V network → connect motor windings in delta
Retea 230V → inconezi infasurarile in triunghi
400V Y = retea 400V (standard Austria) → conectezi in Stern (stea)
400V network (standard in Austria) → connect in star
Retea 400V (standard in Austria) → conectezi in stea
U/min = Umdrehungen pro Minute = rotatii pe minut / rpm
Umdrehung = rotation · pro = per · Minute = minute
Turatia motorului — 2835 rpm = aproape 2 poli / 50Hz
linkslaufend / rechtslaufend
Motor direction: linkslaufend = anticlockwise · rechtslaufend = clockwise
Directie motor: linkslaufend = sens invers · rechtslaufend = sens normal
rund laufen = a merge lin, fara vibratii / to run smoothly
„Läuft der Motor rund?" = Is the motor running smoothly/evenly?
Rund = rotund/lin → motorul merge uniform, fara batai
tauschen = a schimba / a interschimba / to swap
„L1 und L2 tauschen" = swap L1 and L2 — reverses motor direction
Schimbi doua faze = inversezi sensul de rotatie
einstellen = a regla / to set / to adjust
„Den Motorschutzschalter einstellen" = to set the motor protection relay
Verb separabil: „Ich stelle ein." = Reglej.
umdrehen = a inversa / a intoarce
„Die Richtung umdrehen" = to reverse the direction
um + drehen = a intoarce in sens opus
