When it comes to wiring a 120 volt motor starter coil, it’s important to have a clear understanding of the process. A motor starter helps in providing protection to the motor by controlling its electrical circuit. It is an essential component of most electrical systems, especially those that involve heavy-duty motors.
Overview of Motor Starter Coil Wiring Diagram
The wiring diagram for a motor starter coil involves several different components, each with a specific function. These components include the power supply, control circuit, contactor, overload relay, and the motor itself.
The power supply supplies electrical energy to the motor starter coil. This energy is then used to activate the starter coil and initiate the motor’s operation.
The control circuit, on the other hand, consists of various devices that help in controlling the motor’s operation. It includes switches, relays, timers, and other control devices.
The contactor is a vital component of the motor starter coil. It is responsible for the motor’s electrical connection to the power supply. It acts as a switch for the motor’s electrical circuit, enabling or disabling the flow of electrical energy to the motor.
The overload relay is an essential safety device that helps in protecting the motor from overload, overcurrent, and overheating. It is connected to the motor circuit and can monitor the current flowing through it. If the current exceeds the pre-determined limit, the overload relay will trip, thereby cutting off the power supply to the motor.
Lastly, the motor is the primary component that needs to be connected to the starter coil. It is the device that converts electrical energy into mechanical energy, thus enabling it to perform its intended function.
Wiring Diagram for a 120 Volt Motor Starter Coil
The wiring diagram for a 120 volt motor starter coil involves the following steps:
Step 1: Connect the Power Supply to the Motor Starter Coil
The first step involves connecting the power supply to the motor starter coil. This typically involves connecting the power supply to the contactor, which in turn, will energize the starter coil.
Step 2: Connect the Control Circuit to the Motor Starter Coil
The second step is connecting the control circuit to the motor starter coil. This involves connecting the control circuit to the contactor, which will help in controlling the motor’s operation. This step may involve switches, relays, timers, or other control devices, depending on the type of motor being used.
Step 3: Connect the Overload Relay to the Motor Circuit
The third step involves connecting the overload relay to the motor circuit. This is an essential safety device that helps in protecting the motor from overload, overcurrent, and overheating. The overload relay is typically connected to one of the motor starter coil terminals.
Step 4: Connect the Motor to the Motor Starter Coil
The final step is connecting the motor to the motor starter coil. This involves connecting the motor leads to the contactor’s output terminals, thus allowing the motor to receive electrical power from the starter coil.
