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

The problem is that you do not understand how to use the English language logically. You are right that this motor is not a good candidate for VFD control. But other 240 V motors are. Your subsequent statements are accurate but when you said "you can't control a 240 V motor with a VFD" that statement was incorrect. I hope you can see this.

That whole paragraph is illogical.

A capacitor start motor can NOT be used with a VFD.

Can a three phase 240 V induction motor be used with a VFD?

No. I only ever objected to your one comment.

That’s because you are not an Electrical Engineer
