If you’re in the market for a high-quality motor, 12 wire motors are definitely worth considering. They are designed for maximum efficiency, reliability, and performance, and are ideal for a wide range of applications.
What is a 12 Wire Motor?
A 12 wire motor, also known as a dual voltage motor, is a type of electric motor that is capable of operating at two different voltages. This type of motor consists of 12 wires that are connected to the internal winding, corresponding to two different voltage levels. It offers the flexibility of operating at either low or high voltage, making it suitable for a variety of applications.
The motor may be connected to the supply circuit either in a star or delta configuration, depending on the required voltage. In a star connection, the supply voltage is applied between two of the motor terminals, and the other two terminals are connected together. In a delta connection, the supply voltage is applied across three of the motor terminals, with the other three terminals connected together.

How to Wire a 12 Wire Motor
Wiring a 12 wire motor may seem complicated, but it’s actually quite simple. The first step is to consult the wiring diagram, which will show you how to connect each wire to the power source.
Once you have the wiring diagram, follow these steps:
- Disconnect the power supply from the motor.
- Identify the wires for both low and high voltage.
- Connect the wires according to the wiring diagram, depending on the desired voltage and connection type (star or delta).
- Reconnect the power supply and test the motor to ensure it’s running properly.
It’s important to follow the wiring diagram carefully and ensure that the correct wires are connected to the correct terminals. This will help you avoid any potential issues and ensure that the motor operates at maximum efficiency.
FAQ
What are 12 wire motors used for?
12 wire motors are used in a variety of applications, including conveyor belts, pumps, fans, and compressors. They are also commonly used in industrial machinery, such as CNC machines and lathes.
What’s the difference between a 12 wire motor and a 9 wire motor?
9 wire motors are designed to operate at a single voltage, whereas 12 wire motors are capable of operating at two different voltages. This makes 12 wire motors more versatile and suitable for a wider range of applications.
Can a 12 wire motor be wired for single phase?
No, a 12 wire motor is not designed for single-phase operation. It requires a three-phase power supply to operate properly.
What’s the difference between a star connection and a delta connection?
In a star connection, the supply voltage is applied between two of the motor terminals, and the other two terminals are connected together. In a delta connection, the supply voltage is applied across three of the motor terminals, with the other three terminals connected together. The choice of connection type depends on the desired voltage level and application.
How do I determine the correct wire size for a 12 wire motor?
The correct wire size for a 12 wire motor depends on factors such as the motor’s current rating and the length of the wiring run. It’s important to consult the motor’s manufacturer for guidance on wire size and wiring requirements.
Can I wire a 12 wire motor myself?
Wiring a 12 wire motor requires some electrical knowledge and experience. If you’re not confident in your abilities, it’s best to hire a licensed electrician to ensure that the motor is wired correctly and safely.
By following these guidelines, you’ll have a better understanding of 12 wire motors and their wiring requirements. Whether you’re an industrial professional or a DIY enthusiast, the knowledge you gain will help you make informed decisions and get the most out of your motor.
