Method for adding magnet into elevator

Abstract

the invention relates to the technical field of magnet addition into an elevator. A method for adding a magnet into the elevator includes such step as laying a plurality of electromagnetic steel plates on that outside of the stator iron core of a rotary electric machine in the elevator, winding the slot in stator iron core, cutting slot in rotor iron core, alternately laying a plurality of magnetized permanent magnets in the slot, adding magnetized permanent magnets in stator iron core, and adding magnetized permanent magnets in stator iron core. A method for adding the magnet to the elevatorthrough setting electromagnet to drive the spring group inside the hoist to vibrate, minimizes unwanted harmonics generated by the stator, thereby minimizing harmonic losses, The permanent magnet is connected in series distribution, the rotor punch die is the simplest, and each magnet steel is small in volume and easy to install, and the permanent magnet is connected in series distribution, so that the rotating motor inside the hoist is magnetized, the magnetism inside the hoist is increased, and the service life and reliability of the hoist are improved.

Description

technical field [0001] The invention relates to the technical field of adding magnets to a hoist, in particular to a method for adding magnets to a hoist. Background technique [0002] Hoists are large-scale mechanical equipment that are transported by changing potential energy, such as mine hoists and dam crossing hoists. Machines and hoists generally refer to large-scale mechanical equipment with large power and strong lifting capacity. The transportation process is completed by dragging the flexible steel wire rope and the up and down movement of the goods transported by the power machinery. The steel wire rope is an indispensable and important part of the hoisting machinery. Varieties include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope and smooth steel wire rope, etc. [0003] During the long-term use of the hoist, when the rotating motor used inside the hoist has fewer poles, the volume occupied by each pole of the motor ro...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for adding magnets to the hoist, which has the advantages of increasing the magnetic force of the rotating motor inside the hoist, and solves the phenomenon that the rotating motor itself will lose magnetism after the hoist has been used for a period of time There are problems that affect the working efficiency of the hoist
