Permanent magnetic booster

Abstract

The invention relates to a permanent magnetic booster which is characterized in that the permanent magnetic booster comprises a rack and a cylindrical outer casing, two ends of the outer casing are provided with sealing caps, the circumferential inner wall of the outer casing is provided with a plurality of rows and columns of inclined holes, the axis of each inclined hole forms a horizontal included angle with a connecting line between the inclined hole and the central axis of the outer casing, a permanent magnet is fixed in each inclined hole; a roller is rotatably arranged in the outer casing and corresponds to an inclination direction of each inclined hole on the outer casing, an inclined hole is also arranged on the roller and a permanent magnet is also fixed in each inclined hole, the permanent magnet in the outer casing and the permanent magnet in the roller are arranged in a form of opposite homopolarity, two ends of the roller are respectively provided with a projecting shaft, and each projecting shaft is rotatably connected with the sealing cap of the corresponding end through a bearing. The permanent magnetic booster provided by the invention has a clever structural design, is convenient to operate, energy-saving and environmentally-friendly and can be widely applied to all kinds of devices requiring rotary driving.

Description

technical field [0001] The invention relates to a permanent magnet device, in particular to a permanent magnet booster for auxiliary driving of a rotary power mechanism. Background technique [0002] At present, most domestic and international power generation systems use rotating power to do work to generate power, including the use of driving energy such as water conservancy, fire power and wind power. Wind energy is a kind of clean energy, but it generally generates power by rotating the fan blades under strong wind conditions; when the wind is small or there is no wind, the rotating speed of the fan blades will decrease or stand still, thus causing the power generation system to fail. The efficiency of power generation is reduced, or even no electricity can be generated. [0003] The surface magnetic strength of the NdFeB permanent magnets currently produced has reached 6000-8000 Gauss, and between two permanent magnets of the same polarity, a repulsive force of 2-5kg w...

Problems solved by technology

However, since the permanent magnets in this auxiliary device are arranged on the end faces of the disks, the radially utilized space of the disks is limited, and the number of permanent magnets placed is limited, especially its rotational torque is limited by the radial dimensions of the disks. The torque generated is small, and the rotational torque often does not meet the required requirements
