One horsepower electric is 746 watts, so 30 horsepower is 22.4 KW. You don't specify the power factor or motor efficiency, so I am going to assume a power factor of 0.92 and an efficiency of 0.97, fair values for a 30 horsepower motor. Divide 22.4 KW by 0.92 and then by 0.97 and you get 25.1 KVA. Divide that by three and you get 8.4 KVA per winding. You don't say if the motor is delta or wye connected, so I'm going to assume delta, and multiply by the square root of 3 (1.732) to get 14.5 KVA per phase.

What size breaker do you need for 9000W at 440V 3phase?
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
How do you do motor solo run test?
To do a motor solo run test you need to connect the motor to a power supply. Next, you observe the motor's vibration, temperature, and sounds.
Why capacitors are not used in three phase motor?
There is no need. The three-phase supply provides a rotating field in the motor, rotating in the right direction, so there is no need for a starting capacitor.
How many AMPs does a 7.5HP motor need?
depending on 1phase or 3phase voltage motor , the amphere requirement is found outfor 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)for 1phase AC motor : (HP x 746) / (E x Eff x PF)
