I have recently purchased an old heavy (350kg 9 inch joiner/buzzer) that had a 3 phase motor on it. I replaced it with single phase. I had to replace the pully but it was only $20.
I would like to run the power through the NVR switch that the 3 phase power was through. At the moment the powerpoint turns the motor on and off. If anyone has wired single phase through a switch the same as

please let me know the connection so that I can run them through.
Ihave in total spent about $750 for the buzzer and could have got an 8inch Carbatec for $995 (reduced from $1395) so whether it was worth it?
Cheers

How about we find what hp or kw the motor is.
An inverter single to 3 phase may be the option if it's not too big a capacity motor.
The inverters mostly only do 240 volts single phase in to 230 volt 3 phase out.
Many motors in the smaller range have dual voltage operation which makes it easy to achieve re-powering them without the expense of going for "proper" i.e. utility provided 3 phase power.
I do have some inverters available if the kw is low enough.
PM me for details if interested.

Its easy to swap motors around just make sure you get the correct hp and speed as every one else said....I have a spare new 1hp 2850 RPM and switch due to not checking that b4 buying
but the second motor I bought works perfect

I almost went this way with a nice solid old table saw, 3phase. The problem was finding a single phase motor with an exact match for the mounting, which was with the flange, not a pad. Probably not a problem in your case as bandsaw motors seem to be pad mounted. One electrical repairer could provide with an adaptor to align the bolts but it was such a come down in scale as to be a serious weak point, and compromised the solid old cast iron construction of the saw!
Good luck with it!Andy Mac
