So, anyone want to buy a 7.5KW 380 3 Phase Driver, Spindle Servo Motor, cables and braking resistor? The cost to me was $USD 990, plus a bit of tax and sadly the shipment was expensive due to the weight of the motor (60 ish KG). Let me know if interested. Ill possibly stick it up for sale on a few other places too.

Surely it's only the drive you require not the motor.? this wouldn't cost a fortune to replace. What is the model number of the drive, so I can check it against mine which does supposedly work with single-phase, though I haven't tried it, and will use 3 phase anyway?

Thanks.

I thought so too, so queried with them, reckon no go as the motor is wired for 380V. I did notice when I connected it they only expose 3 wires, so cant change from high to low voltage.

The drive is SZGH-S4T7P5, the motor is SZGH10-3-48-7.5/11-4-1500.
