For selection of motor how can we find the motor for appropriate load?

First do some load torque calculation and than consult load torque rating charts of motor to find motor of your need.

First, determine what kind of motor do you need? a single-phase or a3-phase motor?then, find the nameplate of the motor where you can see the appropriate voltage and amperes that can be drawn by the motor. By doing so, you will also come to know how much rating/value of the power supply and the circuit protection you are going to provide for it.
