Unicore combines our prime efficiency of a “wound type” core with the cost and production advantages of “stacked” laminations. AEM Cores provides a large range of custom size single and three phase Unicores in a variety of core types. State-of-the-art machinery, software and production techniques persistently produce repeatable quality cores resulting in highly accurate and reliable cores so therefore lower losses and material savings.
Each Unicore lamination is fully formed through the Distributed Gap Cores cutting machine. The laminations are then stacked to make the core. The core are often used to build a transformer immediately, subject to required losses, without the further processing. For that lowest possible, especially smaller cores, core loss, the Unicore should be annealed.
We are among the leading manufacturers and suppliers of Unicore for several types of power distribution transformers in India. Unicore offered by us is really a wounded type transformer core which can be manufactured using high grade raw materials like silicon steel of different grades with grain orientation. This transformer core is made by stacking the Unicore lamination with the aid of efficient machines.
The Unicores available from us are highly advantageous as it is highly flexible and does not require preset tooling. The core may be used for construction a transformer immediately, without any further processing. This Unicore needs to be annealed to achieve less core loss when compared to cut cores and laminations. These cores can be easily assembled and it highly boosts the efficiency in the transformers. The weight of such Unicores may range approximately 1500kg. The length, thickness as well as other dimensions are made accurate and can also be custom specified.
We offer these Unicore in numerous sizes and shapes based on the requirements in our clients. This transformer core requires less maintenance and it is highly economical. These cores can be popular in a variety of general purpose transformers and distribution transformers using the capacity starting from 1000VA to 10000KVA. Customers can avail these Unicore Machine in customized specifications and then in market leading prices.
High Efficiency – very low core loss and magnetizing current. Flexibility of core sizes and kinds – transformer designers and productions managers have options to reduce their costs and improve their customer’s satisfaction. Basic and highly flexible core production – no mandrels or jigs needed, sizes are quickly and simply designed to the user-friendly machine. The manufacturing process requires reduced space, consumables, inventories, labor and maintenance.
Each individual Unicore lamination is fully formed or “folded” from the Unicore machine. The operator stacks these laminations to form the core. The core may be used to create a transformer immediately, without the further processing. For applications requiring the best core loss, like distribution transformers, the Unicore should be annealed. An annealed Unicore could have losses 15-30 % lower (according to core size) than an un-annealed Unicore.
Various cores types and faces for reduced loss and magnetizing current. Core losses are less than bonded and cut C & E cores, E&I and strip laminations. Core losses are exactly like Distributed Gap cores and Mitered laminations. Various core types and faces for reduced assembly time. Please watch the DUO-Core assembly video of how Unicore Machine may be used yjgfnk reduce assembly time.
Various core types and faces for reduced cost. Lower grades of GOSS or unannealed cores could be supplied to lessen core cost. All common grades of GOSS could be processed from thickness .2 to .35 mm. Unicore sizes vary from .5 to in excess of 1000 kg. Strip width can be from 20 to 300 mm. Window Length, Width and Build-Up are unlimited through the machine.
Short lead times and reduced inventories are possible due to rapid production methods. The flexibility and suppleness provided by the pc controlled Unicore machine allows cores to be tailor-created to suit specific applications. This results in optimization and fine-tuning for individual applications resulting in increased efficiency and reduced costs.
