Are you looking for a 5 wire blower motor wiring diagram? You’ve come to the right place. In this guide, we’ll walk you through everything you need to know about 5 wire blower motors, including how they work, the different types available, and how to wire them correctly.

What is a 5 Wire Blower Motor?

A 5 wire blower motor is a type of motor commonly used in HVAC (heating, ventilation, and air conditioning) systems. As the name suggests, it has five wires that supply power to the motor and control its speed. These motors are designed to be efficient and reliable, making them a popular choice for both residential and commercial applications.

How Does a 5 Wire Blower Motor Work?

5 wire blower motors work by converting electrical energy into mechanical energy. The motor has a rotor (the rotating part) and a stator (the stationary part). When power is supplied to the motor, an electromagnetic field is generated in the stator, which causes the rotor to turn. The speed of the rotor is controlled by adjusting the amount of power supplied to the motor.

Types of 5 Wire Blower Motors

There are two main types of 5 wire blower motors: PSC (permanent split capacitor) and ECM (electronically commutated motor). PSC motors are the more traditional type, while ECM motors are newer and more efficient. Here’s a breakdown of the differences between the two:

Motor Type	Pros	Cons	Price
PSC	Less expensive, simple design, reliable	Less efficient, limited speed control	$50-$100
ECM	Highly efficient, variable speed control, quieter operation	More expensive, more complex design	$150-$300

How to Wire a 5 Wire Blower Motor

Wiring a 5 wire blower motor can be tricky, but it’s important to do it correctly to ensure the motor operates safely and efficiently. Here’s a step-by-step guide:

Step 1: Turn off Power

Before you begin, make sure the power to the HVAC system is turned off. This will prevent any electrical shock or damage to the system.

Step 2: Identify the Wires

The five wires on the motor will be labeled with letters or numbers that indicate their function. Typically, the wires are labeled L1, L2, G, M1, and M2. Consult the manufacturer’s wiring diagram to ensure you know which wire is which.

Step 3: Connect the Ground Wire

Connect the G wire (which is the ground wire) to the ground screw on the motor housing.

Step 4: Connect the Power Supply Wires

Connect the L1 and L2 wires to the power supply. These are typically black and white wires.

Step 5: Connect the Motor Wires

Connect the M1 and M2 wires to the motor. These are typically red and blue wires. Make sure to follow the manufacturer’s wiring diagram to ensure the wires are connected correctly.

Step 6: Test the Motor

Once the wiring is complete, turn on the power to the HVAC system and test the motor to ensure it’s operating correctly.

Conclusion

In conclusion, a 5 wire blower motor is an essential component of an HVAC system. Whether you choose a PSC or ECM motor will depend on your specific needs and budget. Wiring the motor correctly is crucial for safe and efficient operation. If you’re unsure about how to wire your motor, consult a professional HVAC technician.
