What is a common frame size for small motors?

The common frame size for small motors is 56. Frame sizes are standardized measurements that correspond to the mounting dimensions and physical size of the motor. A frame size of 56 typically indicates a motor that has a certain standard height and width, which is commonly used in various applications requiring smaller motors, such as in HVAC systems, pumps, and conveyor systems.

This frame size strikes a balance between power output and physical dimensions, making it versatile for a range of industrial and commercial uses. Frame sizes below 56, such as 48, are less common for small motors and are usually used for specific applications. Larger frame sizes like 66 and 72 correspond to larger motors that are suited for higher power requirements, further distinguishing them from the more widely used 56 frame size in the small motor category.
