Abstract
The utility model relates to a two-stage in-series permanent-magnet speed controller, comprising a cylindrical conductor rotor body, a permanent-magnet rotor and a regulator; the two-stage in-series permanent-magnet speed controller is characterized in that: the permanent-magnet rotor and the cylindrical conductor rotor body are in a two-stage in-series type, only the conductor rotor moves with the width of one conductor, the action area can be regulated to 0 or 100 percent, and the regulating distance is greatly shortened.
Description
Technical field
The utility model relates to a kind of permanent magnetic speed-adjusting device.Specifically a kind of secondary series type permanent-magnet speed governor.
Background technology
The patent No. of the previous application of applicant is 01000678.7 patent, has announced a kind of permanent-magnet speed governor.It comprises: tubular conductor rotor, tubular p-m rotor and adjuster.The tubular conductor rotor is installed on the motor shaft, with the motor synchronous rotation, conductor is installed on it; The tubular p-m rotor is installed on the circumference axle, rotates synchronously with bearing axle, and permanent magnet is installed on it; All there is counterbore circumference axle both sides, to hold motor shaft and bearing axle; Adjuster links to each other with p-m rotor, is responsible for regulating the active area between tubular conductor rotor and the tubular p-m rotor.During work, driven by motor tubular rotating conductor rotor, this moment, tubular conductor rotor and tubular p-m rotor produced relative motion, permanent magnetic field produces eddy current on the tubular conductor rotor, eddy current produces induced field and permanent magnetic field interaction again simultaneously, rotate along the direction identical with the tubular conductor rotor thereby drive the tubular p-m rotor, the result is that transmission of torque with power shaft is to output shaft.Adjuster is by the active area between electric operator adjusting tubular conductor rotor and the tubular p-m rotor, thus the size of regulating the output torque, active area is big more, and transfer torque is big more, and vice versa.
Now, I recognize that above-mentioned patent has following deficiency:
When the designing high-power permanent-magnet speed governor, for increasing active area, must widen conductor, cause: the adjuster adjustable range is oversize, and it is big to take up room, and regulates inconvenient.
Summary of the invention
The utility model provides a kind of adjustable range short, regulates permanent-magnet speed governor more easily, and the technical scheme that it adopted is:
1, p-m rotor is designed to secondary series type, its structure comprises left magnet rotor, right magnet rotor and magnet bracing frame.Left side magnet rotor and right magnet rotor are contained in the both sides of magnet bracing frame respectively, become with a stairstepping baffle group by magnetic support.Magnetic support is an annular, and its outer ring is evenly equipped with the hole that magnet is installed.Stairstepping baffle plate one end links to each other with the magnetic support lateral surface, and the other end links to each other with the magnet bracing frame.Its function is: also played the effect every magnetic when blocking magnet, connecting the magnet bracing frame.The magnet bracing frame be its both sides outer wall of prong like parts respectively with left and right sides magnet rotor, link to each other, the middle part is a tubular, tube links to each other with bearing axle at an end.
2, the conductor with tubular conductor rotor body is mounted to secondary series type equally: its adjacent two conductor separation, one segment distance.In the outer ring of tubular conductor rotor body one circle looping pit is set, is beneficial to heat radiation and loss of weight.The manhole of its bottom is arranged to square, and is extended to form the square through hole boss, so that the motor side shaft to be installed to load-side.
3, adjuster is linked to each other the size of coming the regulating action area by mobile tubular conductor rotor body with tubular conductor rotor body.
During work, adjuster is by electric operator push-and-pull tubular conductor rotor body, with the regulating action area.Because tubular conductor rotor body and p-m rotor all are designed to two-stage tandem, tubular conductor rotor body only need move the width of a conductor, and its active area just is 0, and tubular conductor rotor body and p-m rotor are just thrown off fully.Therefore shortened adjustable range greatly.
The patent No. of the previous application of the utility model and applicant is that 01000678.7 patent is compared, and can bring following beneficial effect:
Contrast high-power permanent magnet speed regulator, the utility model has shortened adjustable range greatly, has also dwindled taking up room in more convenient adjusting greatly.

Embodiment
With reference to accompanying drawing 1～3:
P-m rotor 8 is designed to secondary series type, and its structure comprises left magnet rotor 1, right magnet rotor 2 and magnet bracing frame 3.Left side magnet rotor 1 and right magnet rotor 2 are contained in the both sides of magnet bracing frame 3 respectively, form by a magnetic support 4 and a stairstepping baffle plate 5.Magnetic support 4 is an annular, and magnet 6 is installed in its outer ring.Stairstepping baffle plate 5 one ends link to each other with magnetic support 4 lateral surfaces, and the other end links to each other with magnet bracing frame 3.Magnet bracing frame 3 is that its both sides outer wall of prong like parts links to each other with left and right sides magnet rotor 1,2 respectively, and the middle part is a tubular, and the tube end links to each other with bearing axle.
The conductor 77 ' of tubular conductor rotor body 9 is mounted to secondary series type equally: its adjacent two conductors 77 ' are spaced a distance.One circle looping pit is set in the outer ring of tubular conductor rotor body 9.The manhole of its bottom is arranged to square, and is extended to form square through hole boss 10 to load-side.
Adjuster is linked to each other with tubular conductor rotor body 9, comes regulating action area 11 11 by mobile tubular conductor rotor body 9 ' size.
During work, adjuster is by electric operator push-and-pull tubular conductor rotor body 9, with regulating action area 11 11 '.Because tubular conductor rotor body 9 and p-m rotor 8 all are designed to secondary series type, 9 need of tubular conductor rotor body move the width of a conductor, its active area 11 11 ' just be 0, tubular conductor rotor body 9 and p-m rotor 8 are just thrown off fully.Therefore shortened adjustable range greatly.
