Hi Mick,
the Allen Bradley with the DSD-030 shows 8Nm at 3000rpm.
angular frequency= 3000 x 2 x PI / 60
= 314.1 rad/sec
power =frequency x torque
= 314.1 x 8
= 2513 W
=2.5kW
The BCH2MM152 shows 5Nm at 3000rpm
power = frequency x torque
=314.1 x 5
=1570 W
=1.5 kW
So firstly the power output of the Allen Bradley servo is 2.5kW not 3kW and secondly when is 5Nm ever 'nearly the same' as 8Nm?
You may note that the low speed torque of the Schneider servo is a little higher, in fact closer to 8Nm, than its ultimate torque, 5Nm, at rated speed,
but it does not mean its more powerful, I rather suspect that change occurs by virtue of the transformation effect of the drive rather than any
characteristic of the servo.
