You are assigned to install a motor in a large industrial site. The owner demand that the motor must run at a constant speed over a specific range near a rated load (30 hp). The motor will not run the whole day, rather it will run when needed. The owner will be happy if the motor can be used for any other purpose when it may remain idle. 430V L-L power supply with variable frequency is available on the site. What type of motor will you install? Explain. Does the motor need any additional arrangement for starting? Explain. Assume values of the efficiency (>90%) and the power factor (>0.9) of the motor and determine the KVA rating of the motor. What should be the cable size for the motor load? You can assume any other data required.
