What type of performance data must be included related to braking in propulsion motors?

Braking data is essential information concerning the performance of propulsion motors because it provides insights into how effectively a motor can decelerate and control the vessel. This data typically includes parameters such as the time required to come to a complete stop, the distance traveled during braking, and the overall braking performance under various conditions.

Braking performance is also critical for ensuring safety and compliance with regulatory standards, as it impacts maneuverability and the vessel's ability to respond to operational commands. Understanding the braking characteristics of propulsion motors is necessary for designing systems that can efficiently handle emergencies and operational maneuvers.

While other options like torque performance, energy consumption, and regenerative efficiency hold relevance in evaluating motor performance, they do not specifically address the necessary metrics and considerations associated with braking capabilities. Therefore, the focus on braking data highlights the necessity for detailed specifications that reflect how well the propulsion system can manage deceleration, which is crucial for safe operation.
