Robot of crawling based on variation in permeability leads

The utility model relates to a robot of crawling based on variation in permeability leads. The robot of should crawling for in placing the clearance between stator core and rotor core, in order to span in the stator coil groove or on changeing the subcoil groove. Should crawl the robot includes the unilateral mechanism of first, second, both ends respectively with coupling mechanism first, that the unilateral mechanism of second is connected to and guiding mechanism, the unilateral mechanism of first, second can adsorb on stator core or rotor core, and can move on stator core or rotor core, and guiding mechanism is including locating the first magnetic conductivity probe in the first unilateral mechanism and locating the second magnetic conductivity probe in the unilateral mechanism of second. Adopt the aforesaid to creep the robot and examine and repair and test with the rotor subassembly stator module, need not take out the rotor subassembly, ability labour saving and time saving, the security is higher.
