3. Belt Drive System:
   A belt drive system uses a rubber belt to move the door. This type of system is preferred for its quiet operation and smooth movement. The Home Improvement Research Institute suggests that belt drives are ideal for homes with living spaces adjacent to the garage due to their low noise levels. The downside is that they may not be as durable as chain drive systems when lifting very heavy doors.

4. Chain Drive System:
   A chain drive system relies on a metal chain to open and close the garage door. This type is known for its strength and ability to handle heavier doors. However, it tends to be noisier than belt drive systems. Research by the National Association of Home Builders in 2020 indicates that chain drives are often the most cost-effective option, making them a preferred choice for budget-conscious consumers.

5. Screw Drive System:
   A screw drive system uses a threaded steel rod to lift the door. This system requires less maintenance than others but can be slower in operation. The International Door Association states that screw drives are suitable for moderate-weight doors but may not perform well in extreme temperatures. They offer a balance of cost, efficiency, and durability.

Evaluating the pros and cons of each motor type, along with the operational systems they encompass, can greatly impact your selection process for a garage door opener.
