Abstract

The utility model discloses an improved rotor magnet structure of a synchronous servo motor, which belongs to the electromechanical field. The utility model is provided with a plurality of sheet-shaped magnets which are in the arc shape. The straight side edge of the magnet is respectively provided with bevels with the same direction and the same angle. After the magnets are assembled to form a rotor magnetic ring, even chutes are formed on the magnetic ring so as to reduce the rotation distance, and the rotor magnetic ring is easy to control at low speed. Because the straight side edge of each magnet is provided with a bevel with the same direction and the same angle, the magnet is easy to form the even chutes after assembled. Thus, the assembly work is convenient and fast, and the efficiency of the productivity is improved. The utility model has the advantages of convenient operation, small rotation distance and easy control at low speed. The bevels are aligned to form the chutes when the utility model is assembled.

Description

The rotor magnet structure-improved of synchronous servo motor

Technical field

The utility model relates to electrical category, and particularly a kind of rotor magnet structure-improved of synchronous servo motor refers to a kind ofly be constituted average skewed slot after assembling especially, and making changes apart from less the rotor magnet structure that is easy to control when low speed.

Background technology

As everyone knows, the general employed rotor magnet of synchronous servo motor, usually shown in accompanying drawing 1 and accompanying drawing 2, be magnet circle 1, and form skewed slot 12 in magnet circle 1 by most arcuation magnet 11 stacked combination, but because the side of each magnet 11 is a vertical configuration, therefore, after from top to bottom arranging, form as the ladder and cause the inequality of skewed slot 12, therefore, there is following shortcoming in traditional rotor magnet circle 1:

1, because the side of magnet 11 is vertically, skewed slot 12 difficulty presents, and causes the puzzlement in the assembling;

2, the skewed slot 12 of forming the back formation makes skewed slot 12 inequalities can't make commentaries on classics apart from dwindling for stepped;

3, owing to skewed slot 12 inequalities, difficult control when low speed.

The utility model content

The purpose of this utility model is to provide a kind of rotor magnet structure-improved of synchronous servo motor, has solved existing magnet arrangement and has been difficult for assembling, can't dwindles when changeing distance and low speed than problems such as difficult controls.

The technical solution of the utility model is: mainly be provided with most flaky magnets, make these magnet generally arc shapeds, the inclined-plane that directly is made as equidirectional, equal angular respectively of magnet to side, after making most group of magnets be combined into the rotor magnet circle, be able to constitute average skewed slot in the magnet circle, the commentaries on classics distance is dwindled, and more easy to control when low speed; Because each magnet is to be equidirectional and inclined-plane that angle is identical to side directly, makes magnet be easy to form average skewed slot after assembling, and then makes assembling operation more convenient, quick, to improve production capacity efficient.

Advantage of the present utility model is: because the magnet side is made as the inclined-plane, only need during assembling the inclined-plane alignment can be constituted skewed slot, operation is quite convenient; Because skewed slot is average, therefore making changes apart from less; Because average skewed slot makes servo motor more easy to control when low speed.

Fig. 1, Fig. 2 are rotor magnet schematic perspective view commonly used;

Fig. 3, Fig. 4 are the schematic perspective view of the utility model magnet;

Fig. 5, Fig. 6 are combination schematic perspective view of the present utility model.

Embodiment:

Shown in accompanying drawing 3 and accompanying drawing 4, the utility model mainly is provided with most magnet 21, these magnet 21 generally arc shapeds, and make magnet 21 directly to side be made as respectively equidirectional, with the inclined-plane 22 of angle, make most magnet 21 after being assembled into the rotor magnet circle, be able to inclined-plane, form average skewed slot in the magnet circle because of magnet 21.

Shown in accompanying drawing 5 and accompanying drawing 6, during assembling, with the magnet 21 of majority stacked combination from top to bottom, to constitute a magnet circle 2, make magnet circle 2 form most skewed slots 23, because the side of magnet 21 is inclined-plane 22, during assembling, do not need to calculate the distance of rank portion, make skewed slot 23 be able on average as traditional magnet.

Claims

1, a kind of rotor magnet structure-improved of synchronous servo motor, it is characterized in that: be provided with most flaky magnets, these magnet generally arc shapeds, the inclined-plane that directly is made as equidirectional, equal angular respectively of magnet to side, the rotor magnet circle is made of the magnet of majority, and the magnet circle constitutes average skewed slot.
