Understanding the Basics of Electrical Starters
Before we dive into the reasons behind the effectiveness of hitting a starter, it’s essential to understand the basics of how electrical starters work. An electrical starter is a device that helps to start an electric motor or engine by providing a high surge of current to the motor windings. The starter consists of a solenoid, a set of contacts, and a motor. When the starter is activated, the solenoid pulls the contacts together, allowing the high current to flow to the motor windings and start the engine.
The Role of Contacts in Electrical Starters
The contacts in an electrical starter play a critical role in its operation. The contacts are responsible for connecting and disconnecting the high current flow to the motor windings. Over time, the contacts can become worn out or corroded, leading to a reduction in the starter’s performance. When the contacts are dirty or corroded, they may not connect properly, preventing the high current from flowing to the motor windings and causing the starter to fail.
Why Corrosion and Wear Occur
Corrosion and wear on the contacts can occur due to various factors, including moisture, dirt, and high temperatures. When the starter is exposed to moisture, it can cause the contacts to corrode, leading to a reduction in their conductivity. Similarly, dirt and debris can accumulate on the contacts, preventing them from connecting properly. High temperatures can also cause the contacts to wear out faster, leading to a reduction in the starter’s performance.
The Science Behind Hitting a Starter
Now that we understand the basics of electrical starters and the role of contacts, let’s explore the science behind hitting a starter. When you hit a starter, you are essentially applying a physical force to the contacts. This force can help to clean the contacts, remove dirt and debris, and improve their conductivity. The physical force can also help to reseated the contacts, ensuring they connect properly and allowing the high current to flow to the motor windings.
The Effect of Vibration on Contacts
Hitting a starter can also create a vibration that helps to loosen any corrosion or dirt that may be accumulated on the contacts. This vibration can help to restore the contacts’ conductivity, allowing the starter to work properly. The vibration can also help to reseated the contacts, ensuring they connect properly and allowing the high current to flow to the motor windings.
Real-World Examples
There are many real-world examples of how hitting a starter can make it work. For instance, car starters often require a physical tap to get them working again. Similarly, generators and pumps may also require a physical hit to get them started. In some cases, industrial equipment may also require a physical tap to get them working again.
