Motor connections
(OP)
Help, can anybody please provide connection information for a three phase two speed SCHORCH mixer motor (Type K953/4-2M Delta-Star-Star) 9 terminals.
The original panel has one main and four auxiliary contactors. Motor is being used on a Papenmeier mixer. (1966)
Thanks in advance to anyone who can help out, we’ve been struggling with this problem for a while.

RE: Motor connections
That took me all of 3 minutes on Google, mostly because Papenmeier was an old brand name.
The reason I bring that up is because even if someone here can tell you the motor connections, it may not help if they don't know what was being done with it. 5 contactors in a motor control scheme is complicated to say the least, most likely a Star-delta starting, 2 or 3 speed running arrangement. I have seen some Westfalia separators with that kind of control cabinet and I would never attempt to reconnect it without a very detailed drawing.
A more up-to-date solution might be to dump the contactor control and just install a VFD. Since the Papenmeier name went away in 1999 it could be that VFDs were too expensive back then so they opted for this complicated arrangement. I don't know of any multi-speed mixers now that are NOT controlled by VFDs, it's just too easy in comparison.

RE: Motor connections
I've done a lot of repair and servicing of Schorch machines but i think i can't figure out your query, maybe the unit is too old for me or maybe you lack to describe your scenario.
Better to post the detail.
