It is to add more power to the motor to help it start spinning. You can replace the motor with one that does not have a capacitor, but why? Most motors of this type do have it so it isn't a big issue.

Remember that a capacitor stores electricity and then supplies it if/when the current drops. When the blower kicks on, it needs a little more juice than when it's just running. The cap keeps the electricity flowing properly.
If the capacitor is easily transferred to the other motor you're thinking about, you should do so. Otherwise, get an approved replacement part for your heater so you don't damage the furnace.

It's what is referred to as a start capacitor. I don't know of any blower fans that don't have them. It isn't too hard to replace but if you're not confident in doing it yourself hire an electrician or HVAC tech. It won't be too expensive, maybe $100 parts and labor.

I don't know what kind of heater/furnace you have, but the blower is sized to the heater in order to move a specific amount of air across its heat exchanger/element etc. Dont start cobbling around with it. All you're going to do is overheat the unit, stress limit (safety) switches, and cause yourself alot of grief.
