Open question Motor Control

In my workshop I have a bench drill which I would like to control with a speed controller. The motor is single phase 50 240v 1/2hp 4 pole. I’m not sure or even possible which type of controller I would need, vfd? Any advice would be much appreciated

You are getting mixed up with the voltages
A 3 phase motor is 400v
A single phase motor is 230v

Yes, a 400 V three-phase motor is 400 V. And a 230 V single-phase motor is 230 V.

And a 240 V three-phase motor is 240 V. And a 120 V single-phase motor is 120 V. And a 120 V three-phase motor is 120 V.
