CLAMP DEVICE AND METHOD OF MANUFACTURING STATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240235338 titled 'CLAMP DEVICE AND METHOD OF MANUFACTURING STATOR

The abstract describes a patent application related to a stator core design with two shafts that restrict the positions of end portions in the circumferential direction.

The first shaft and the second shaft have grooves that define the positions of the end portions.
The first shaft presses a curved portion radially outward, while the second shaft presses a curved portion radially inward.
This design clamps segment coils in place, ensuring the end portions are in contact with each other.

- Key Features and Innovation:**

Innovative stator core design with shafts and grooves to secure end portions.
Radial pressing of curved portions for effective clamping of segment coils.

- Potential Applications:**

Electric motors
Generators
Wind turbines

- Problems Solved:**

Ensures proper alignment and positioning of segment coils in stator cores.
Prevents displacement or misalignment of end portions during operation.

- Benefits:**

Improved efficiency and performance of electric machines.
Enhanced stability and durability of stator cores.

- Commercial Applications:**

Electric motor manufacturers can utilize this technology to enhance the reliability and efficiency of their products, leading to increased market competitiveness and customer satisfaction.

- Questions about Stator Core Design:**

1. How does the design of the shafts and grooves contribute to the stability of the stator core? 2. What are the potential cost implications of implementing this innovative stator core design in electric machines?

Original Abstract Submitted

the first shaft and the second shaft restrict the positions of the first end portion and the second end portion in the circumferential direction of the stator core with the first end portion and the second end portion interposed therebetween. each of the first shaft and the second shaft has a groove. the groove is defined by a first side wall, a second side wall, and an end wall connecting the first side wall and the second side wall. a first side wall of the first shaft presses the first curved portion radially outward of the stator core. the second side wall of the second shaft presses the second curved portion radially inward of the stator core. thereby, the first segment coil and the second segment coil are clamped in a state where the first end portion and the second end portion are brought into contact with each other.
