HBS860H 12NM VS iHSV60 for Router 3000x2000mm

You are building a ....what ?
Plasma?
Router?
House?

In general,
For plasma use steppers
Anything else use servos if you can afford them and the time it takes to tune and make them work properly.

Kkkk sorry... Its a router with r&p module 2 with 30 teeth

That will make 18.nn CM of move for one rotation so you will need a lot of reduction to make that useful.
How heavy will the gantry be ?

This is my michine, extruded aluminum, with steel plates, take a look.

I can not see it, it just lets me download it, but i do not use windows so no way of opening it.

First i think direct drive the gantry, later on i will buy some planetary gearbox, thats why iam thinking in big motor.

Direct driving a pinion that does over 18CM per rotation is not going to work with any of those motors, the 860 is a stepper motor drive driving a 12NM motor that will cause extreme vibrations of the machine but it should have enough power, the 400W servo will have to spin very slowly with that pinion so it will not have enough power and will constantly overheat trying to get in position or just never reach it.

i cant understand the diference between hbs860h 12nm and ihsv60

both use 400w power supply this let me think both are 400w... they have the same power?

The first should be a Stepper system, the second is a servo system. The power thing is not quite equal here as stepper motor do have more torque than servos, but they can not spin fast as they loose that torque at anything above 200RPM while servo motors spin easily to 2000 or 3000RPM. Also steppers have more power for the same size.
For the pinions you have, the minimum reduction should be 1:10 for a stepper system and 1:15 for a servo system.
