I've been thinking of fitting a Tacho to my fobco drill. It's got a 3 phase 240v motor, fed from an inverter. If the gearing is equal, I can infer the drill speed from the motor shaft speed (i need to check that the motor pulley and quill pulleys are equal, but let's assume they are for now).
I can't seem to find a setting on the inverter to output rpm, but I wondered if I could fit something like this:
You can specify the number of poles, and it's fed off the motor supply, and apparently it will output rpm. Apart from being expensive, I think it would do the job?
Has anyone gone this route, or am I over complicating this?
