Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet speed regulators, in particular to an energy-saving permanent magnet automatic speed regulator. Background Art

[0002] In the prior art, both motors and engines have an optimal efficiency speed. Once deviating from this speed, their working efficiency will decrease. Therefore, the application of permanent magnet speed regulation technology on constant-speed prime movers has achieved remarkable energy-saving effects. The permanent magnet speed regulator mainly consists of a conductor rotor, a permanent magnet rotor, and an adjusting mechanism. The conductor rotor is installed on the input shaft, and the permanent magnet rotor is installed on the output shaft. When the conductor rotor rotates, relative movement is generated between the conductor rotor and the permanent magnet rotor, and eddy currents are generated on the conductor rotor by the permanent magnetic field; at the same time, the eddy currents generate an induced magnetic field that interacts with the permanent magnetic field, thereby driving the permanent magnet rotor to rotate in the same direction as the conductor rotor, and transmitting the torque of the input shaft to the output shaft. The magnitude of the output torque is related to the distance or meshing area between the permanent magnet rotor and the conductor rotor. The larger the distance or meshing area, the greater the torque and the higher the speed, and vice versa. However, the permanent magnet speed regulator in the prior art uses a gear meshing method for speed regulation. It uses the contact between gears to transmit force and adjust the rotation speed. Due to the contact and meshing between gears, part of the energy will be lost, and the structure of the existing permanent magnet speed regulator is relatively complex. During assembly, precise cooperation between various parts is required to achieve the speed regulation function of the speed regulator, resulting in a relatively large assembly difficulty and being not easy to operate.

[0003] The Chinese invention patent with the application number: 201310093401.1 discloses a permanent magnet speed regulation, braking or load device capable of steplessly adjusting the magnetic field intensity. It has a single turntable / multi-turntable type, single drum / multi-drum type, turntable-drum combination type or turntable-drum composite type structure, mainly consisting of an active rotor, a passive rotor, a working magnetic coupling air gap / medium, a leakage magnetic circuit / air gap, a leakage magnetic circuit air gap adjusting disk, and an adjusting mechanism. The active rotor consists of at least one set of active rotor disks and a matching active coupling mechanism. The active rotor disks are connected to the power shaft through the active coupling mechanism. The passive rotor consists of at least one set of passive rotor disks and a matching passive coupling mechanism or a braking connection mechanism. However, this permanent magnet speed regulation, braking or load device capable of steplessly adjusting the magnetic field intensity has a relatively complex structure. During assembly, precise cooperation between various parts is required to achieve the speed regulation function of the speed regulator, resulting in a relatively large assembly difficulty and being not easy to operate. It uses a gear meshing method for speed regulation. The contact between gears is used to transmit force and adjust the rotation speed. Due to the contact and meshing between gears, part of the energy will be lost. Summary of the Utility Model

[0033] Through the cooperation of the output mechanism and the speed regulating mechanism, a non-contact automatic speed regulating combination is formed. The closed coil or copper ring 9 cuts the magnetic force lines of the speed regulating magnets 17 to generate a changing electromagnetic damping force. As the relative speed gradually increases, the electromagnetic damping force will become larger and larger, so that the speed regulating magnets 17 and the closed coil or copper ring 9 move in the same direction. The greater the relative speed difference between the speed regulating magnets 17 and the closed coil or copper ring 9, the greater the output torque, and the smaller the relative speed difference, the smaller the output torque, so as to realize the automatic speed regulation function. In the working state, the output mechanism can rotate relative to the speed regulating mechanism. When the output mechanism rotates relative to the speed regulating mechanism, an electromagnetic damping force is generated between the two, so as to drive the speed regulating mechanism to rotate, and the speed of the speed regulating mechanism changes with the change of the speed of the output mechanism.
