In order to solve the above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways：A kind of
Stepwise permanent-magnet speed governor, including input terminal and output end, the input axis connection on input terminal and motor, output end in load
Axis connection is exported, input terminal includes the first rotating shaft with input axis connection, and first rotating shaft is equipped with and is led with what motor rotated synchronously
Body cylinder, output end include the second shaft being connected with exporting axis, and the second shaft is equipped with the permanent magnetism pallet rotated synchronously with load
And the adjuster for adjusting the back-and-forth motion of permanent magnetism pallet, conductor cylinder is cylindrical in shape structure, in conductor cylinder inner ring at least provided with one
A magnetic guiding loop is arranged with magnetic support ring on permanent magnetism pallet, and magnetic support ring circumferential direction inside direction is uniformly provided with magnet, and the setting of magnetic support ring exists
Inside conductor cylinder, and the position of magnetic support ring and magnetic guiding loop corresponds, and there are certain gaps between magnetic guiding loop and magnetic support ring；
Conductor cylinder is internally provided with multiple first stair-steps, and magnetic guiding loop is mounted on the first stair-step, and the first ladder
The diameter of step is gradually expanded by conductor cylinder Inside To Outside, and permanent magnetism pallet is equipped with second-order corresponding with the first stair-step
Halfpace rank, magnetic support ring are arranged on the second stair-step.
The technical solution that the utility model further limits is：
Step permanent-magnet speed governor above-mentioned, magnetic guiding loop are copper ring.
Step permanent-magnet speed governor above-mentioned, the second shaft are equipped with torque plate, are equipped between torque plate and permanent magnetism pallet
Sliding pin for transmitting torque.
The utility model has the beneficial effects that：Existing conductor cylinder is axially inside spaced the multiple magnetic guiding loops of setting, in order to
The speed of load can be adjusted to be zero by permanent-magnet speed governor, so there must be a certain distance between magnetic guiding loop, and should be away from
From the width for being at least greater than or equal to a magnetic guiding loop, so the distance is inevitable, but permanent-magnet speed governor is also increased
Axial dimension；
Pass through in the technical program, since the gap of magnetic guiding loop and magnetic support ring is smaller, the torque of generation is bigger, in conductor cylinder
Multiple first stair-steps are arranged in inside, and the second stair-step is arranged on permanent magnetism pallet, and such magnetic guiding loop is logical with magnetic support ring
The engagement for crossing stepped form, using height distance between step, when adjuster driving permanent magnetism pallet is displaced outwardly, the magnetic conduction in outside
Ring is staggered with magnetic support ring, and the gap between the magnetic support ring and the magnetic guiding loop in outside of inside increases, to realize speed-regulating function, in this way
The distance between magnetic guiding loop in the prior art is eliminated, so as to reduce the size of conductor cylinder and permanent magnetism pallet axial direction, is shortened
The axial dimension of permanent-magnet speed governor, and then reduce the axially mounted size of output shaft and input shaft, make the permanent-magnet speed governor more
Different installation environments is adapted to, its versatility is increased.
