Description

A kind of pin-connected panel AC servo motor stator of segmental structure

Technical field

The utility model relates to AC servo motor more particularly to permanent-magnet alternating current servo motors, specifically a kind of point The pin-connected panel AC servo motor stator of segment structure.

Background technique

Existing AC servo motor structure, including casing, stator, end cap and rotor, usual permanent magnet are placed on rotor.Figure 1 show a kind of typical stator, and the yoke portion of each tooth of magnetizer connects together, the entire stator magnetizer of this structure It is an entirety, referred to as monolithic construction.Tooth socket 4, coiling in tooth socket 4 are offered on magnetizer 10.

Fig. 2 show a kind of typical assembled stator, and the magnetizer is spliced into circle by multiple independent point of magnetizers 1 A complete stator magnetizer is welded in the seam crossing of each point of magnetizer outer circle again after shape.Magnetizer 1 is divided to be equipped with Tooth socket 4 is used for coiling 3.Magnetizer 1 is divided first to cover upper skeleton 2 before assembly and wind coil 3.In general, the knot of tooth socket 4 Structure has straight trough and skewed slot.When using straight groove structure, the cogging torque of motor is big, is not suitable for high accuracy positioning control field.

To reduce cogging torque, pin-connected panel AC servo motor stator generallys use flume structure.It is a kind of more typical Flume structure, the tooth socket of stator are still straight groove structure in pole body part, are only skewed slot in pole shoe.The stator of the flume structure has Two important parameters, i.e. the week down fold angle α and oblique α 1 in axial chute angle.

Refer to that the tooth socket side positioned at motor rear end on magnetizer pole shoe is electric relative to being located at referring to Fig. 6, all down fold angle α Angle of the tooth socket side of machine front end in motor circumferential offset.

Refer to the angle between the tooth socket 4 of motor and machine shaft center line referring to Fig. 4, the oblique α 1 in axial chute angle.

The oblique α 1 in axial chute angle and the relationship of all down fold angle α are as shown in Equation (1):

(1)

In formula, D is the diameter of stator bore of motor, and L is the axial length of motor stator core.

From formula (1) as it can be seen that when the diameter of stator bore of motor and when dividing magnetizer down fold angle α being a definite value in 1 week, no With length motor its divide the axial chute angle α 1 of magnetizer 1 to be different.That is: right when the axial length of motor is 4L The axial chute angle answered is α 2, then the angle of α 2 and α 1 is not identical.For the motor of same model but different size, determine Sub- iron core internal diameter is identical, and core length is different, thus axial chute angle is all different, brings many fiber crops to punching and management It is tired, not only increase cost of manufacture, and poor universality.

Summary of the invention

To be solved in the utility model is above-mentioned technical problem of the existing technology, it is desirable to provide a kind of segmental structure Pin-connected panel AC servo motor stator improves production efficiency to simplify the punching and management of iron core, reduces manufacturing cost.

To solve the above problems, the utility model uses following technical scheme: a kind of pin-connected panel exchange of segmental structure is watched Motor stator, including magnetizer, coil and skeleton are taken, the magnetizer is spliced by multiple independent point of magnetizers, often It is a divide tooth socket is offered on magnetizer, the tooth socket pole shoe be in skewed slot, it is characterised in that each divide magnetizer by least It is stacked before and after two points of magnetic conduction body units to constitute, each divide magnetic conduction body unit structure having the same and length.

The pin-connected panel AC servo motor stator of a kind of segmental structure of the utility model, by magnetizer by equal length Two to multiple points magnetic conduction body units are stacked to be formed, the same a set of stator structure of base type design, for the difference under the model Different quantity need to only be divided magnetic conduction body unit to be laid out, bring many sides to punching and management by the motor of specification Just, it is suitable for batch production, improves production efficiency, reduce production and management cost.

It is stacked before and after two to multiple points magnetic conduction body units to constitute a point of magnetizer as the improvement of the utility model, Described dividing in the tooth socket of magnetizer puts on the skeleton, and the coil described in coiling on the skeleton constitutes one point Magnetizer component；After multiple points of magnetizer components are spliced into circle, one is formed by welding in the seam crossing of each point of magnetizer outer circle Complete stator.

Magnetizer is divided to be 12 described in as a further improvement of the utility model, 10 pole of rotor, the week of the skewed slot Down fold angle is 6 degree.Axial chute angle is pressed at this timeIt calculates and obtains.
