Simcenter Electric machine design solutions deliver a complete design and analysis platform; tailor-made for motor and generator design engineers to model, document, and estimate future systems.
OVERVIEW
The world of electric motors
Electric Machines are omnipresent. They are commonly found in almost all applications such as transportation, aerospace, generators in power plants, actuators, pumps, blowers, electric guns, HVAC-compressors, home appliances, etc.
Simcenter Electric machine design solutions deliver a complete design and analysis platform; tailor-made for motor and generator design engineers to model, document, and estimate future systems or reorganize current ones while staying in compliance with industry standards.
The conventional approach to electric motor design is either classical or FEA. Classical methods (analytical and equivalent circuit) are fast and the least accurate, while FEA has the highest fidelity, but is slow. Simcenter Motorsolve combines the synergies of both these approaches: it is fast and accurate enough for rapid electric motor design exploration.
Simcenter Motorsolve
The template-based design solution has a unique interface that is easy to use and flexible enough to handle practically any motor and generator topology, with provision for custom rotors and stators.
Simcenter Motorsolve simulates machine performance using equivalent circuit and our unique automated finite element analysis engine, with the synergy of automating the non-productive tasks such as mesh refinement for rapid and accurate analysis of electric machines.
Why Simcenter Motorsolve ?
The template based design interface combined along with the fastness of analytical/equivalent circuit based calculation makes the design procedure smarter and faster. Thus multiple design iterations can be done to meet the need to explore various designs, resulting in the decrease in time to market for new and redesigned products.
Risks of not being in compliance with future standards may be catastrophic for motor manufacturers and suppliers , so the need of designing a high fidelity virtual prototype of the model is important before taking the product into the market. Finite element based analysis is a proven method to predict the electrical, mechanical and thermal performance of the machine.
The true power of Motorsolve lies in the Automated FEA Engine which insures accurate replication of the laboratory prototype.
Only FEA simulations accurately predict:
- Performance when there is saturation
- Hysteresis, eddy current & winding loss
- Deep bar effects
In this modern industry, engineers are trying to shift from the conventional design models to more advanced custom designs to improve the machine performance and efficiency. As the models are becoming more and more complex , it is essential that a design tool should able to handle the modelling and simulation with limited effort and less time consumption. When the available inbuilt templates do not match the desired shape Simceneter Motorsolve support cad importing functionality to create custom stator and rotor geometries.
The software also has dedicated libraries for industry-specific applications like air conditioning, automotive transmission, liquid propulsion, fuel cells, etc. Control system library in Simcenter Amesim helps in the design and validation of complex control system logics.
Temperature is an important factor that affects the performance of electric machines. Due to their thermal design, electric machines can suffer problems such as insulation breakdown, reduction in torque provided, shortened lifetimes and so on. In addition, the size of a motor is ultimately dependent upon the thermal rating. In order to predict machine temperatures, the design of the electric machine needs to take thermal factors into account.
As systems become more electrified, designers are required to ensure compliance of electric drive systems in terms of electromagnetic, thermal, noise, vibration, and structural analysis. Simcenter Motorsolve allows to integrate motor design models with system analysis solution such as Simcenter Amesim to meet this needs. An integrated workflow allows designers to be more decisive from the start, compressing the overall design cycle.
