[QUOTE="ryanm, post: 213062, member: 14671"] Thanks a lot for the answers. In reply to Q1, 99% of the motors are under 2.2kW, so I've only really seen the 400 V Star / 230V delta. Thanks for the explaination RE the links on the single phase motor, I've never really looked at one before, but I understand what you mean :) Q2: Yes the new motor was deinitely wired correctly, even the name plate says 400 V STAR at 5.7 Amps, and 230 V Delta at 9.x Amps. I phoned Stroter where we got the motor (and gearbox) from, and he couldn't undertand it, but could see what he had supplied us as was going to get back to us (but hasn't). The original motor was from Germany, but the new one doesn't actually have a name on the nameplate weirdly, but the terminal box lid has Siemens on it. [/QUOTE]
