Abstract

The invention discloses a permanent magnet electromagnetic needle. The permanent magnet electromagnetic needle comprises a shell and an end cover; an upper positioning plate base is arranged on the top of the interior of the shell; a lower positioning plate base is arranged at the bottom of the interior of the shell; a silicon steel sheet sleeve is arranged between the upper positioning plate baseand the lower positioning plate base; a coil is arranged in the silicon steel sheet sleeve; a limiting sleeve is arranged in the coil; a rotor is arranged in the limiting sleeve; and the rotor comprises a rotor main body, a rotor upper end and a rotor lower end. By virtue of the permanent magnet electromagnetic needle, relative balance can be kept between the rotor and the magnetic field, the matching degree of the coil magnetic field and the rotor magnetic field can be improved, the efficiency problem caused by magnetic leakage is solved, sound decibel is obviously lowered, the service lifeof the whole apparatus is prolonged, and the temperature of the whole apparatus is lowered; and in addition, the electromagnetic leakage part generated by the coil is returned to the coil through thesilicon steel sheet sleeve, and the silicon steel sheet sleeve also generates a partial magnetic effect, so that the circularity of the coil magnetic field is improved, the efficiency of the whole electromagnetic coil is further improved, magnetic noise generated by magnetic leakage is lowered, the whole apparatus can reach the magnetic full strength, and the efficiency can be improved by 10%.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, in particular to a permanent magnet electromagnetic needle. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit, and its main function is to convert electrical energy into mechanical energy. [0003] The Chinese patent disclosed a utility model patent named motor (application number: 201220020273.9) on 2012.01.17. It includes a stator, a rotor and a motor shaft, and also includes a circuit board. The circuit board is arranged perpendicular to the motor shaft. A heat shield is arranged between the side and the stator, and the other side of the circuit boar...
