DC Motor Torque: 95% Power to Stator, 5% to Motor?

AI Thread Summary
In a conventional DC motor, 95% of the power is directed to the motor, while only 5% goes to the stator. A hypothetical motor with 95% power to the stator and only 5% to the motor would still operate but would be highly inefficient. This inefficiency results in minimal shaft output, making it economically unviable for practical applications. The discussion emphasizes the importance of power distribution for optimal motor performance. Ultimately, efficient power allocation is crucial for effective motor functionality.

In a conventional DC motor 95 percent of the power is supplied to the motor while only 5 percent of the power is supplied to the stator. consider the torque equation. what if you have a motor that has 95percent power supplied to the stator and 5 percent to the motor. the motor will still run but why do we not use this motor?

It sounds like you're referring to the motor efficiency. If the shaft output is only 5% then the motor is not very efficient. So it would not be economical to use it.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
