Which type of motor + drive , AC or DC is better for the above application ?
What are the pros and cons of using an AC Drive vs using a Dc Drive.
Thanking in advance,

this is not an usual application, you have to specify better your needs and your environment.
Inertia is a very important factor to be considered, can you supply some data?
Do you have the need to recover energy during reversing, or friction load is enough high to stop the motor?
What is the value of "full speed"? Do you have a gearbox to reduce speed?
Please add as more info as possible, you will have a more detailed reply.
What is the total installed power in this location? What is medium voltage supply?
Happy new year
