I have a nice Husqvarna brush cutter where the motor has a failed bearing and they stopped making that model. One of my backburner projects is to electrify it. Current candidate is a small router motor: probably has enough power and it can meet the duty cycle requirements. Like I said in my other post, the biggest issue is the mechanical coupling from motor to device: they're all non-standard.
We could have general purpose electric motors by now but the corporations are instead pushing proprietary formats that we can't retool ourselves upon us. More money for them this way.
