DYNAMO INSTRUMENTATION CARRIER Russian patent published in 1998 - IPC

FIELD: serviceability check of dynamos incorporating stator with ferromagnetic armature and rotor. SUBSTANCE: frame part of carrier mounts instruments for serviceability check of dynamo (video camera, ultrasonic monitoring head) and at least one first set of wheels with at least three wheels used to provide for carrier displacement in armature-to-rotor gap. Auxiliary frame mounts second set of wheels displaced relative to first one by hoist. Two sets of wheels enable carrier displacement in two relatively perpendicular directions. For holding instrumentation carrier tight against yoke, each wheel is provided with cylindrical permanent magnet coaxial relative to axis of revolution of wheel. Dynamo stator and/or rotor is easily checked up from air gap between them. No stiff connecting or guide members (buses) are required for carrier. EFFECT: simplified design, improved reliability and reproducibility of check results. 14 cl, 4 dwg
