Transformer Winding Machines, Their Significance, and Types

Transformer is one of the most crucial components of any electrical circuit. A transformer is basically used to convert (increase or decrease) the voltage, depending upon the maximum allowable voltage of an application. Thus, there are two main types of transformers, namely, step-up and step-down transformers. The main difference between these two types of transformers is the number of windings. Thus, winding becomes the most important part of this electrical device. These windings are manufactured with the help of transformer winding machines.

Transformers are used in a wide range of applications varying from a mobile charger to huge industries. Thus, the rating of the transformers can vary from VA to MVA. VA is the voltage and current rating of a transformer. Thus, based on the applications, transformers with different windings are used. There are different types of transformer winding machines used to manufacture transformers with different VA/MVA ratings. Besides this, different types of winding machines are required, depending upon low volume or high volume production. What are these machines? What is the significance of these machines in manufacturing winding? Are you intrigued to know more about them? Read the following post to get a detailed understanding of these machines.

What Are the Types of Transformer Winding Machines?

As discussed earlier, transformers with different VA ratings require different coil winding machines. Based on this, there are three main types of winding machines used. These three types of machines are as follows:

  • Manual Transformer Winding Machines –

    These transformer winding machines can either be operated by hand or with the help of a small motor. Transformer coils can be wound precisely by using the manual transformer winding machines. One of the major advantages of these machines is that they are light weight. This makes them portable and can be carried from one place to another easily.

  • Programmable Transformer Winding Machines –

    The programmable transformer winding machines are an advanced version of winding machines, which feature a 16 Bit microprocessor for smart operation. These machines also have a stepper motor, which is capable of winding up to 750 RPM. In these machines, various functions of a transformer are set-up and programmed. This is one of the biggest advantages of these machines, as programming these functions provides high level of precision in operation. Thus, coils of transformer can be wound easily. Some striking features of these achiness are:

    • They have a built-in production counter, which keeps an eye on the number of transformer coil winding.
    • There are a number of menu items, which can be programmed easily.
    • These winding machines are equipped with a speed control knob. This helps adjust the speed.
    • Another important and beneficial feature of these transformer winding machines is that they have a display.
  • Automatic Transformer Winding Machines –

    As their name suggests, the automatic transformer winding machines do their job with no or very less need of human interference. The advantage of using these types of winding machines is that they help reduce the labor costs. Various tasks can be fed to these machines, and they are operated using computerized programs. The multi-spindle feature of these machines help make the equipment multi-coil winding. Multiple coil windings can be done simultaneously using these types of machines.

These were the three basic types of transformer winding machines used by a number of manufacturing firms. To now more on the topic, you can always contact industry experts, such as Armature Coil, who has a decent experience in providing transformer winding and manufacturing services.
