Bodine Electric Company is a leading manufacturer of fractional horsepower (FHP = less than 1 HP/746 watts) small gearmotors, motors, and motor speed controls in North America. Bodine Electric motors are used in a wide variety of applications.

How to Wire Bodine Electric Motor

Here are some examples of Bodine Electric motor wiring diagrams:

Single-phase, 2-wire motor

Figure on this is a two-phase line type, and figure below is a schematic design of a three-wire single-phase system. I believe you understand that the two single-phase line type uses only a portion of the 100 V of the single-phase three-wire system.

Figure 1: Single-phase, 2-wire motor wiring diagram.

This is the simplest type of Bodine Electric motor wiring diagram. The two wires are connected to the power supply, and the motor will run in one direction. To reverse the direction of the motor, simply swap the connections of the two wires.

Single-phase, 3-wire motor

This type of Bodine Electric motor has a capacitor that is used to improve the motor’s performance. The capacitor is connected to the two main power wires. The third wire is the start wire, and it is connected to one of the main power wires through a switch.

When the switch is closed, the capacitor is connected to the power supply and the motor starts running. When the switch is opened, the capacitor is disconnected from the power supply and the motor stops running.

Three-phase motor

Three-phase motors are more complex than single-phase motors, and they require a special power supply. The three wires of the motor are connected to the three phases of the power supply. The motor will start running as soon as it is connected to the power supply.

Identifying the type of Bodine Electric motor

There are many different types of Bodine Electric motors, each with its own unique wiring diagram. It is important to identify the type of motor you have before attempting to wire it. This information can be found on the motor’s nameplate.

Bodine Electric manufactures a wide variety of electric motors, including:

1. Permanent magnet DC motors
2. Brushless DC motors
3. AC induction motors
4. Inverter duty motors
5. Gearmotors

Understanding the wiring diagram

To understand the wiring diagram of a Bodine Electric motor, you need to be familiar with the basic symbols used in electrical diagrams. The most common symbols are:

1. Wire: A solid line represents a wire.
2. Terminal: A circle represents a terminal. Terminals are used to connect wires to electrical components.
3. Switch: A switch is represented by two lines that cross each other. Switches are used to turn electrical circuits on and off.
4. Capacitor: A capacitor is represented by two parallel lines with a curved line in between. Capacitors are used to store electrical energy.
5. Resistor: A resistor is represented by a zigzag line. Resistors are used to limit the flow of electrical current.

Once you are familiar with the basic symbols, you can start to interpret the wiring diagram. The wiring diagram will show you how to connect the wires from the power supply to the motor terminals. It will also show you any other components that need to be connected to the motor, such as switches and capacitors.

Choosing the correct wire gauge

The wire gauge is the thickness of the wire. To choose the correct wire gauge for a Bodine Electric motor, you need to consider the following factors:

1. The current rating of the motor: The current rating of the motor is the maximum amount of current that the motor can draw. The wire gauge you choose must be able to handle the motor’s current rating.
2. The length of the wire run: The longer the wire run, the larger the wire gauge you need to use. This is because longer wire runs have more resistance, which can cause the voltage at the motor to drop.
3. The ambient temperature: The ambient temperature is the temperature of the air around the wire. If the ambient temperature is high, you need to use a larger wire gauge. This is because high temperatures can cause the wire to overheat, which can reduce its current carrying capacity.

Preparing the wires

To prepare the wires of a Bodine Electric motor, you will need to:

1. Strip the insulation off the ends of the wires. Be careful not to strip too much insulation off, or you could damage the wires. You can use a wire stripper to make this task easier.
2. Tin the ends of the wires. This will help to prevent the wires from oxidizing and will make it easier to solder the wires to the motor terminals. You can use a soldering iron and some solder to tin the ends of the wires.
3. Connect the wires to the motor terminals. The wiring diagram for your motor will show you how to connect the wires to the motor terminals. Be sure to follow the wiring diagram carefully to avoid making any mistakes.
4. Insulate the exposed wires. Once the wires are connected to the motor terminals, you need to insulate the exposed wires to prevent short circuits. You can use electrical tape or heat shrink tubing to insulate the wires.

Connecting the wires to the motor

The wiring diagram will show you how to connect the wires to the motor terminals. Be sure to connect the wires correctly, or you could damage the motor.

Securing the wires

Once the wires are connected to the motor, you need to secure them in place. This will prevent the wires from coming loose and causing a short circuit.

To secure the wires of a Bodine Electric motor, you can use a variety of methods, such as:

• Cable ties: Cable ties are a quick and easy way to secure wires. Simply wrap the cable tie around the wires and tighten it.
• Electrical tape: Electrical tape can also be used to secure wires. However, it is not as durable as cable ties and may need to be replaced over time.
• Wire loom: A wire loom is a flexible tube that can be used to protect and secure wires. Wire loom is often used in applications where the wires are exposed to harsh environments.
• Heat shrink tubing: Heat shrink tubing is a type of tubing that shrinks when heated. Heat shrink tubing can be used to insulate and secure wires.

Testing the motor

Once the motor is wired, you need to test it to make sure it is working properly. To do this, simply connect the motor to the power supply and turn it on. If the motor runs smoothly, then it is wired correctly.

Troubleshooting

If your Bodine Electric motor is not working properly, there are a few things you can do to troubleshoot the problem:

1. Check the power supply. Make sure that the power supply is turned on and that the motor is properly connected to the power supply.
2. Check the wiring. Make sure that the wires are properly connected to the motor terminals. Follow the wiring diagram carefully to avoid making any mistakes.
3. Check the brushes. If your motor has brushes, make sure that the brushes are clean and in good condition. You can use a brush cleaner to clean the brushes.
4. Check the armature. If your motor has an armature, make sure that the armature is not damaged. You can inspect the armature for signs of damage, such as burnt windings or broken wires.
5. Check the bearings. If your motor has bearings, make sure that the bearings are lubricated and in good condition. You can lubricate the bearings with a light oil or grease.
