Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor cores, in particular to a servo motor rotor core structure. Background Art

[0002] The motor rotor core is the iron core part of the motor rotor. It is generally composed of 0.5mm thick silicon steel sheets punched and stacked. These silicon steel sheets are insulated from each other to reduce energy loss. There are many slots on the outer circumference of the rotor core for placing the rotor winding.

[0003] Conventional rotor punchings are mostly made by integral stamping and blanking, and the material utilization rate is not high. Because it is an integral stamping manufacturing, the equipment requirements are higher and the equipment cost is also relatively high. The use of petal-type rotor punchings can reduce equipment costs and improve material utilization.

[0004] The existing split-petal structure rotor punchings are prone to displacement during installation, thereby affecting the installation efficiency of the rotor punchings. In addition, the existing rotor punchings lack a heat dissipation structure. When the rotor is working, the heat inside the motor will be high. The high internal temperature of the motor will affect the temperature rise of the motor, resulting in a reduction in the life of the motor. Therefore, the utility model provides a servo motor rotor core structure. Utility Model Content

The coolant can be filled into the liquid storage chamber 210 through the coolant inlet 208. When the rotor unit is working, the heat dissipation of the rotor unit can be dissipated through the heat dissipation fins 201. To avoid damage to internal components due to excessively high temperatures during operation, when the rotor unit rotates, the wire block 302 drives the heat dissipation fins 201 to rotate through the heat dissipation grooves 309. When the heat dissipation fins 201 rotate, they also drive the inner sleeve 202 to rotate. The annular slide rails, annular slide rails B205 and balls 204 set at both ends of the inner sleeve 202 and the outer sleeve 206 can make the inner sleeve 202 rotate more smoothly.
