Conventional Motor Housings are usually made of cast or forged metal. Metals used in housings include steel or corrosion resistant alloys. The damping characteristics, weight and other properties of the housing are a function of the materials used to construct the housing and the geometry of the motor structure.
What are the advantages of 3D printing technology to produce Motor Housing?
What are the technical characteristics of Motor Housing?
What are the developments in the production method of Motor Housings?
3D printing technology produces Motor Housing cost-effectively, reduces waste and reduces risk of mold revisions
In addition to the rapid production of Motor Housing, the advantages of 3D printing technology also have the cost advantage of small batch order production. Since the 3D printing process does not require any molds, small batch order production can bring huge cost benefits. In addition, VJ's high-precision industrial 3D printing system can bring extremely low waste or scrap rate, because when using traditional modeling molds to make models, any modification to the prototype will be followed by modification or re-production of the mold mold. Using 3D printing technology, any changes only need to be applied to the 3D data, and the model can be printed at any time to verify the design.
The water jacket is the core part of the die-casting motor shell, which nests the motor stator to ensure the normal operation of the rotor. Its air tightness, force performance and concentricity directly affect the safety performance of the motor. Based on comprehensive cost and application necessity, we The water jacket part of the motor shell with high performance and safety requirements is selected to optimize the process, and a new semi-solid die-casting process is used. The safety performance of Motor Housing is ensured efficiently with the lowest process cost.
Compared with the die-casting or casting-molded water jackets in the prior art, the drawn semi-solid die-cast motor shell water jacket has excellent air-tightness and force-bearing performance. At the same time, the advanced friction stir welding process is used to complete the flow channel sealing cavity. The two-pronged approach ensures the normal and safe operation of the motor.
With the continuous emergence of new electric vehicle platforms and the need to meet mass production conditions, the requirements for light weight, small installation space, high specific power and efficiency, and low overall cost of electric motors have risen sharply, which has also driven changes in electric motor architectures. Therefore, the design of motor integration has become a hot spot. This means that the motor consists of only a few components, such as the housing, gearbox and power electronics, which are individually cast and assembled through various techniques and then integrated into the Motor Housing. The integrated design approach also has manufacturing advantages, which reduce manufacturing costs by eliminating critical interfaces. At the same time, weight loss and performance improvement can also be achieved. The cooling channel of the motor can be directly formed during casting, which has more design and optimization space. Due to the complex structure of the casting, the casting of the motor casing is mostly CPS or gravity casting.
Patented new technology PCM (patternless casting manufacturing) has been applied to Guangdong Fenghua Zhuoli Technology Co., Ltd manufacturing which improved the traditional casting efficiency rapidly.
