| 1. | This type of plant does not use rotating machines for energy conversion.
|
| 2. | Aircraft zones differ in usage, flammable fluids, flammable vapors, or rotating machines.
|
| 3. | Armored vehicles with rotating machine gun turrets patrolled city streets.
|
| 4. | Both traction control equipment and rotating machines ( motors, generators and auxiliary machines ) were manufactured.
|
| 5. | The critical speed of a rotating machine occurs when the rotational speed matches its natural frequency.
|
| 6. | Instead of using miniature rotating machines, accurately calibrated phase-shifting transformers were built to simulate electrical machines.
|
| 7. | Rotating machines, where the direction of the magnetic field can change, gain no benefit from grain-oriented steel.
|
| 8. | The armature, in contrast, must carry shaft torque in a rotating machine or force in a linear machine.
|
| 9. | Also, motor generators require more routine maintenance due their nature as rotating machines, given the bearings and slip rings.
|
| 10. | In a rotating machine, the field coils are wound on an iron magnetic core which guides the magnetic field lines.
