Yes worth a look because it's linear torque so there rating will be higher than the 2.2Kw at lower speeds because the torque on these falls away quickly when speed is lowered unless using a more expensive Vector drive and this isn't always possible depending on the VFD make.?

Servo will offer more torque across the speed range.! . . . . You can get some largish and Cheap Servo drives from ali-express so may be worth a look and it will make a proper job of it.!
