Dear All,

Kindly tell me that how much torque a 3 phase motor of 7.5 KW and 1500 RPM will have in Nm.

As Lyn implies, which torque do you mean?

1500rpm? Is it synchronous?

Otherwise, rated torque is normally calculated by: power (watts) ÷ speed (rad/s) from nameplate information.

What is the context of your query???

If it isn't connected to a mechanical load, the torque will be zero, as it is the load that presents the torque to the motor.
