Invertor required

Id just pick one off Ebay. Loads of Hyuanyang's available.

That said, not sure the complexities of a dual speed motor ...... perhaps someone smarter can comment :-)

Be careful - that's a 415V motor, not a 240V motor that the usual invertors will drive directly. You need a rather different invertor to run a 415V three-phase motor from a 240V single-phase supply as it needs the capability to increase voltage. Possibly something like this.

Some dual speed motors are just not suited to inverters, check if anyone else - Google search - has converted the make & model you have.
It may be cheaper and quicker to re-motor and vfd at the same time.
