| 31. | It had a single field coil, and two principal poles, each split halfway to create two pairs of poles.
|
| 32. | The maximum field strength is 1.2 tesla produced by 20 toroidal field coils spaced symmetrically in the toroidal direction.
|
| 33. | The " sense coil ", another loop antenna, is placed in the area between the field coils.
|
| 34. | This means that there is no externally driven current on the device axis and so there are no external toroidal field coils.
|
| 35. | In a shunt wound motor, the field coils are connected in parallel, or " shunted " to the armature coils.
|
| 36. | Rotating the sense coil in the field coils has the same output as rotating the entire loop antenna in the original field.
|
| 37. | Flexible plate is used in electric motor and generator armatures, field coil insulation, and magnet and motor starters, and transformers.
|
| 38. | The " dynamo-electric machine " employed self-powering electromagnetic field coils rather than permanent magnets to create the stator field.
|
| 39. | In a series wound motor, the field coils are connected electrically in series with the armature coils ( via the brushes ).
|
| 40. | The current generated in the magneto is transmitted by wires attached to the rotating shaft to the dynamo's rotating field coil.
