Sounds to me like a replacement for your replacement is in order.
If the motor is defective there isn't much you can do for it.

Generally a roaring noise is something out of balance or a bad bearing. If yours gets better after a few minutes I'd bet it's a bearing that gets hot and loosens up enough to turn more freely. OK for the short term but it might indicate that it's in for a short life.
Also, since you didn't say what motor you replaced or what it does go through and check to make sure it's installed properly and that nothing is loose. If it's a motor for a fan or blower the fan might be loose and it eventually vibrates and finds it's own balance.
