Abstract
The utility model diskloses a permanent-magnet intelligent speed-regulation energy-saving apparatus, which comprises a permanent magnet disk, a main shaft and a conductor copper disk. The permanent magnet disk and the conductor copper disk are sleeved on the main shaft in a mutually opposed way. The main shaft drives the permanent magnet disk to rotate and approach the conductor copper disk through a screw key located between the permanent magnet disk and the main shaft. Elastic elements arranged between the permanent magnet disk and the main shaft limit the approaching of the permanent magnet disk to the conductor copper disk. By means of the cooperation between the screw key and the elastic elements, the speed-regulation apparatus achieves automatic adjustment of the gap or the coupling degree between the permanent magnet disk and the conductor copper disk in line with a load condition. Furthermore, the permanent-magnet intelligent speed-regulation energy-saving apparatus has the characteristics of simple structure, convenient installation and long service lifetime.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of permanent magnet intelligent speed-regulating energy-saving device as shown in Figure 1, comprise permanent magnetic disk 1, main shaft 2 and conductive copper dish 3, permanent magnetic disk 1 and conductive copper dish 3 are sleeved on main shaft 2 relative to one another, main shaft 2 drives permanent magnetic disk 1 rotation close conductive copper dish 3 by the screw key 4 between permanent magnetic disk 1 and main shaft 2, restriction permanent magnetic disk 1 is set between permanent magnetic disk 1 and main shaft 2 near the flexible member 5 of conductive copper dish 3, the preferred helical spline of screw key.
Flexible member 5 is compression spring, on main shaft 2, has back-up ring, and compression spring is enclosed within on main shaft 2, between back-up ring and permanent magnetic disk 1.
On main shaft 2, have two compression springs that length is different, the spring constant of the compression spring that length is long is less than the spring constant of the short compression spring of length.The compression spring that length is long also play motor out of service after, the reset of permanent magnetic disk 1, guarantees the pliability of again starting, protection motor useful life.The apolegamy of the spring constant of compression spring (coefficient of stiffiness), can guarantee the final running speed of load, therefore can, according to different needs and the actual conditions of load, mate different compression springs and the optimum condition of proof load, thereby obtain efficient result.
Between conductive copper dish 3 and main shaft 2, bearing is set.
The course of work is as follows:
When electric motor starting rotates together with main shaft 2, at this moment permanent magnetic disk 1 is also followed rotation, and it has certain moment of inertia, and there is a certain amount of lotus root to close with conductive copper dish 3, thereby be also subject to a power that hinders its rotation, make the speed of itself and main shaft 2 have certain speed poor, at this moment permanent magnetic disk 1 moves inwards, while compression pressure spring, and when suffered always the making a concerted effort when axial component equates with the spring force of compression spring of permanent magnetic disk 1, main shaft 2 and permanent magnetic disk 1 assembly synchronous rotary, at this moment permanent magnetic disk 1 is also in relative static conditions.
Therefore when the load being driven by conductive copper dish 3 increases, its rotating speed moment changes to little direction, permanent magnetic disk 1 changes to large direction with conductive copper dish 3 moment relative velocity, at this moment a powerful Ampere force of 3 moments generations of permanent magnetic disk 1 and conductive copper dish, because of powerful active force and the reaction force between them, and make permanent magnetic disk 1 and main shaft 2 have a very little differential, and permanent magnetic disk 1 is moved again inwards, increased lotus root right.And when conductive copper dish 3 load that drives while reducing, its rotating speed moment changes to large direction, permanent magnetic disk 1 changes to little direction with conductive copper dish 3 moment relative velocity, at this moment permanent magnetic disk 1 outwards moves, and makes to have reduced lotus root right.
As can be seen here, this device can be used in changeable work condition environment, and constant load rotating speed intelligently, improvement load running rule, reaches energy-efficient effect.
