and an adsorption plate (842) fixed at the end part of the limiting rod (841), and a pressurizing spring (843) is arranged between the adsorption plate (842) and the attaching arc plate (82).
9. The magnetic steel mounting device for a large synchronous motor according to claim 8, wherein: the limit rod (841) is made of metal, strong magnetism can be added to the limit rod through an external connection cable of the external connector (811), and the auxiliary adsorption plate (842) adsorbs and fixes the magnetic steel.
10. A method of mounting a magnetic steel mounting device for a large synchronous motor according to any one of claims 1 to 9, comprising the steps of:
s1, sleeving the motor rotor (3) at the middle position of the fixed rod (1), and fixing the motor rotor (3) through a fixed nut (2);
s2, fixing an assembly body consisting of a guide sleeve (4), a supporting sleeve rod (5) and a driving assembly (7) at two ends of the fixed rod (1), and pre-installing an adjusting block (61) and an adjusting ring (62) on the guide sleeve (4);
s3, firstly hinging the adjusting rod (63) and the adjusting sleeve (64), sleeving the adjusting sleeve (64) on the attaching assembly (8), and then hinging the other end of the adjusting rod (63) on the adjusting ring (62);
s4, adjusting relative rotation angles of the adjusting ring (62) and the adjusting block (61) to enable the center of the attaching assembly (8) to be opposite to the attaching surface of the motor rotor (3);
s5, adsorbing the magnetic steel on the adsorption plate (842), and adding strong magnetism to the limit rod (841) to strengthen the adsorption stability;
s6, starting a driving motor to control a screw rod (72) to rotate, and driving the screw rod to drive through a driving block (74) so that the adjusting block (61) and an adjusting ring (62) synchronously slide in a mutually-far mode, driving an arc block (81) to approach to the center under the driving of an adjusting rod (63) and an adjusting sleeve (64), and then attaching magnetic steel to the surface of a motor rotor (3) until the end part of an attaching arc plate (82) is attached, so that the magnetic steel is installed;
s7, magnetic force opposite to the magnetic steel is added to the limiting rod (841), so that the adsorption plate (842) is separated from the magnetic steel, the driving motor is adjusted to rotate reversely, the relative positions of the adjusting ring (62) and the adjusting block (61) are subsequently readjusted, the magnetic steel is fixed on the adsorption plate (842), and the magnetic steel is repeatedly installed.
