I am dealing with an old mixer - the motor has me a bit puzzled. I'm guessing this motor is a bit more than 25 years old. It is a Siemens 1LA4 223 V3 225M - I haven't been able to locate details in a catalog, but the nameplate lists the voltage as 240 delta, 160 amp, 52 kW. It is connected to a 240v Wye-Delta starter (six leads). I would like to run this from a VFD - and get off the 240v service (switch to 480v).
I'm guessing I can run this motor from a 480v VFD, and set the Volts at 240 - but am a bit concerned on proper sizing and is the drive going to be particularly noisy running at reduced voltage?
From reading other posts on here, there are a number of really smart people here - any advice would be appreciated.
