The model number “TB213TTTS18653AAL” for a Marathon Electric motor contains several pieces of information that specify the motor’s characteristics and design features. While the exact decoding can depend on Marathon Electric’s specific model number conventions, here’s a general breakdown that could apply to many electric motor model numbers:

• TB: This prefix often indicates the product line or specific type of motor, possibly referring to the frame type or design series.
• 213: This part of the model number typically specifies the frame size or physical dimensions of the motor. Frame size is crucial as it relates to mounting and the motor’s physical compatibility with the machinery it’s intended for.
• TT: This could represent the motor’s enclosure type, which indicates how the motor is built to prevent the ingress of various environmental factors like dust or water.
• TS: This part might specify other design features or modifications from the standard product line, such as a special shaft or mounting configuration.
• 18653: This sequence often provides information about the motor’s electrical characteristics, such as horsepower, speed, voltage, or other performance-related attributes.
• AAL: This suffix could indicate specific modifications, options, or special features that the motor has, like a particular type of bearing, insulation class, or a special type of rotor.

For an exact and detailed explanation of what each segment of the model number means, it’s best to consult directly with Marathon Electric or refer to the specific product documentation. Motor manufacturers have their own unique coding systems, and a Marathon representative or product catalog could provide the most accurate interpretation of their model numbers.
