[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.

[0003] However, the installation operation process of the rotor, stator and other components inside the existing servo motor is relatively inconvenient. Due to the unreasonable distribution of the number of magnetic poles, it will cause problems such as high power consumption and substandard power output. Therefore, a stator wheel structure for a servo motor is needed to solve the problems existing in the prior art. Utility Model Content

[0006] As a preferred embodiment, a plurality of stator slots in a ring array are provided on the inner surface of the connecting cavity, a stator magnetic block is fixedly connected to the top of the stator slots, and a rectangular array of excitation coils are wound between the stator slots, and the excitation coils are integrally wound.

[0007] As a preferred implementation, a rotor core is disposed on the inner surface of the connecting cavity, and a fixed outer ring is fixedly connected to the front and rear sides of the outer surface of the rotor core.

[0008] As a preferred embodiment, six magnets in a ring array are fixedly connected to the top of the outer surface of the fixed outer ring, and six pillars in a ring array are fixedly connected to the top of the outer surface of the fixed outer ring. The pillars are arranged between two of the pillars, and the fixed outer ring and the pillars are narrow at the top and wide at the bottom.

[0009] As a preferred embodiment, a support rod is fixedly connected to the center of the front and rear sides of the outer surface of the rotor core, the support rod is arranged at the center of the fixed outer ring, the top of the support rod is fixedly connected to a rotating rod, the top of the rotating rod is fixedly connected to a connecting rod, and a connecting groove is provided at the top of the outer surface of the connecting rod.

[0010] As a preferred implementation manner, the rotor core rotates inside the connecting cavity.

[0011] Compared with the prior art, the stator wheel structure for a servo motor provided by the utility model has at least the following beneficial effects:

[0012] (1) The rotor core is slid into the connecting cavity through the motor stator wheel, so that the rotor core is flush with the motor stator wheel, and the connecting block is inserted into the groove, so that the excitation coil in the stator slot wedge and the stator magnetic block generate magnetic force, and the magnetic force generated by the magnets on the front and back sides of the rotor core interacts with each other, so that the rotor core in the connecting cavity can more efficiently complete the energy and power conversion in the process of sending and receiving pulses to rotate, the power output is stronger, and the power loss is lower, thereby improving the rotation efficiency of the structure.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] See also Figure 1-4 The utility model provides a stator wheel structure for a servo motor, including a motor stator wheel 1, the outer surface of the motor stator wheel 1 is provided with four grooves 2 in a ring array, the four grooves 2 are narrow outside and wide inside, the four grooves 2 are slidably connected with connecting blocks 3 inside, and the outer surface of the motor stator wheel 1 is provided with connecting cavities 4 on both sides of the front and rear.

[0021] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that a plurality of stator slots 5 in a ring array are opened on the inner surface of the connecting cavity 4, and a stator magnetic block 6 is fixedly connected to the top of the stator slot 5. An excitation coil 7 in a rectangular array is wound between the stator slots 5, and the excitation coil 7 is wound as an integral whole. Since the excitation coil 7 is wound as an integral whole, the excitation coil 7 can improve the rotation efficiency of the motor, reduce energy consumption and extend the service life when the motor is working.

The pillar 11 is arranged between two pillars 11, and the fixed outer ring 9 and the pillars 11 are narrow at the top and wide at the bottom.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that a support rod 12 is fixedly connected at the center of the front and rear sides of the outer surface of the rotor core 8, and the support rod 12 is arranged at the center of the fixed outer ring 9. The top of the support rod 12 is fixedly connected to a rotating rod 13, and the top of the rotating rod 13 is fixedly connected to a connecting rod 14. A connecting groove 15 is provided on the top of the outer surface of the connecting rod 14. Through the motor stator wheel 1, the rotor core 8 is slid into the connecting cavity 4, so that the rotor core 8 is flush with the motor stator wheel 1, and the connecting block 3 is inserted into the groove 2, so that the excitation coil 7 in the stator slot wedge 5 and the stator magnetic block 6 generate magnetic force, so that the magnetic force generated by the magnets 10 on the front and rear sides of the rotor core 8, the interaction between the two makes the rotor core 8 in the connecting cavity 4 more efficient in completing energy and power conversion during the process of sending and receiving pulses for rotation, with stronger power output and lower electrical loss, thereby improving the rotation efficiency of the structure.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the rotor core 8 rotates inside the connecting cavity 4.

[0026] This scheme has the following working process: first, the rotor core 8 is slid into the interior of the connecting cavity 4, so that the front and rear top ends of the rotor core 8 are flush with the outer surfaces of the two sides of the motor stator wheel 1, so that the motor stator wheel 1 and the rotor core 8 are combined into one, and then connected to the object that needs to be rotated through the connecting rod, and then an iron block is placed inside the connecting groove to increase the friction force to make the connection more stable, and then the connecting block 3 is inserted into the groove 2, so that the excitation coil 7 in the stator slot wedge 5 and the stator magnetic block 6 generate magnetic force, so that the magnetic force generated by the magnets 10 on the front and rear sides of the rotor core 8, the interaction between the two makes the rotor core 8 in the connecting cavity 4 in the process of sending receiving pulses to rotate, can more efficiently complete the energy and power conversion, the power output is stronger, and the power loss is lower.

[0027] According to the above working process, it can be known that: through the motor stator wheel 1, the rotor core 8 is slid into the connecting cavity 4, so that the rotor core 8 is flush with the motor stator wheel 1, and the connecting block 3 is inserted into the groove 2, so that the excitation coil 7 in the stator slot wedge 5 and the stator magnetic block 6 generate magnetic force, so that the magnetic force generated by the magnets 10 on the front and rear sides of the rotor core 8, the interaction between the two makes the rotor core 8 in the connecting cavity 4 in the process of sending and receiving pulses to rotate, more efficient energy power conversion can be completed, the power output is stronger, and the power loss is lower, thereby improving the rotation efficiency of the structure, because the stator slot wedge 5 is evenly distributed on the inner surface of the connecting cavity 4, so that the magnetic force on the outer surface of the rotor core 8 is balanced, so that the rotor core 8 is more stable during the rotation process, thereby improving the rotation efficiency of the structure.
