What would be the best motor to use if you need it to run continuously?

For continuous operation, a brushless DC (BLDC) motor is often the best choice due to its efficiency, reliability, and low maintenance requirements. These motors generate less heat and have a longer lifespan compared to brushed motors. Additionally, they provide smooth torque and can operate quietly, making them ideal for various applications that require continuous running. Other options, such as stepper motors, may also work depending on the specific application needs, but BLDC motors generally offer superior performance for continuous use.
