Preferably, being equipped with sliding shoe in the magnetic yoke body, the sliding shoe is described between adjacent segmentation magnetic yoke
Segmentation magnetic yoke, which is equipped with, makes sliding shoe along the sliding slot of magnetic yoke body radial slippage, and the sliding slot bottom, which is equipped with to magnetic yoke body center position, to be made
For the spring of sliding shoe, the outer end of the sliding shoe, which is equipped with, acts on the contact jaw that positioning pin compresses segmentation magnetic yoke.Rotor stops
When rotation stop is moved, sliding shoe slides to magnetic yoke body center position under the action of the spring, sliding shoe close to magnetic yoke body center, when rotor from
When stationary state starts, since sliding shoe is close to magnetic yoke body center, rotary inertia is smaller, raises speed convenient for rotor.Work as rotor
When rotation, sliding shoe is conducive to rotor and keeps stabilized (steady-state) speed since the outside side slip of centrifugal action, rotor moment of inertia increase.
Meanwhile sliding shoe be displaced outwardly after act on positioning pin so that positioning pin compresses adjacent segmentation magnetic yoke, further increase magnetic yoke
Body rigidity advantageously ensures that rotor rotational stability.
The beneficial effects of the present invention are: on-site assembly and monobloc forging magnetic yoke one can be transported with piecemeal by having had both slab magnetic yoke
Sample reduces rotor center part structure, reduces installation difficulty and production and processing cost.
