Integrated Case Geared Motor Stator Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing geared motor and damper device structures require multiple components and high positional accuracy for end plate fixation, increasing manufacturing costs and labor due to the need for two end plates and complex assembly processes.
Innovation Solution
A geared motor design that uses a single case member with integrated radial, axial, and circumferential positioning parts to accurately position the stator and rotor support shaft, eliminating the need for end plates and reducing the number of components, thereby simplifying the assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two end plates are used to support the stator and rotor support shaft, then the structural stability is improved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent merges the functions of two separate end plates into a single integrated case member. The first case member simultaneously supports the stator at one end and the rotor support shaft at the other end, eliminating the need for separate end plates while maintaining structural stability through unified design
2Manufacturing precision
If two end plates are used with fixation processes, then the positional accuracy is improved, but the manufacturing labor and time increase
Solution Approach 1:
The case member is designed as a single integrated component that incorporates all positioning and support functions. The first support part for the rotor support shaft and the stator support structure are formed as one piece, eliminating multiple fixation processes and reducing assembly labor while maintaining high positional accuracy
3Manufacturing precision
If high positional accuracy is required between stator core and end plate, then the positioning precision is improved, but the manufacturing cost and labor increase
Solution Approach 1:
The case member integrates the positioning features directly into its structure. The first support part for the rotor support shaft and stator positioning elements are formed as integral parts of the case member, eliminating the need for separate end plates and reducing the complexity of achieving high positioning precision while lowering manufacturing costs

AI summary
A geared motor may include a first case member, a support member disposed on one side in a motor axial line direction with respect to the first case member and connected with the first case member, a stator in a tube shape disposed between the first case member and the support member, a rotor disposed on an inner side with respect to the stator, a rotor support shaft rotatably supporting the rotor, and a gear train structured to transmit rotation of the rotor. The first case member may be provided with a radial direction positioning part which positions the stator in a radial direction and a first support part for the rotor support shaft which supports an end part on the other side in the motor axial line direction of the rotor support shaft.
