Inspection vehicle for inspecting an air gap between the rotor and the stator of a generator

摘要

An inspection vehicle (24) for inspecting an air gap (14) between the rotor (11) and the stator (12) of a generator (10) includes drive elements (26, 27) for the independent progressive movement in the air gap (14). A particularly compact construction and flexible application is achieved by the drive elements (26, 27) being formed as elongated, flexionally elastic, torsionally rigid, magnetic rolls.

主权项

1. An inspection vehicle for inspecting an air gap between the rotor and the stator of a generator, the inspection vehicle comprising:
a housing or a carrier structure; and at least one rotatable drive element extending from opposite sides of the housing or of the carrier structure for moving the housing or carrier structure in the air gap, the drive elements comprising elongated, flexionally elastic, torsionally rigid, magnetic rolls to magnetically engage a portion of the outer circumference of the rotor or a portion of the inner circumference of the stator.
