What is a traversing machine four-in-one ESC?
In the fields of drones and flying machines, electronic speed regulators (electronic speed regulators) are the core component for controlling motor speed. In recent years, the four-in-one ESC has gradually become the first choice for ride-through enthusiasts due to its advantages such as high integration and easy installation. This article will introduce in detail the definition, working principle, advantages and popular product recommendations of four-in-one ESC to help you fully understand this technology.
1. Definition of 4-in-1 ESC
The four-in-one ESC is a device that integrates four independent electronic speed regulators on one circuit board. It is mainly used to control the four brushless motors of the ride-through machine. Compared with traditional split ESCs, the four-in-one ESC reduces cable connections, reduces weight, and improves system reliability and response speed.
2. Working principle of four-in-one ESC
The four-in-one ESC adjusts the speed of the motor by receiving the PWM (Pulse Width Modulation) signal sent by the flight controller (flight controller). Its core features include:
1.Signal decoding: Analyze the instructions sent by the flight controller.
2.Current control: Adjust the output current according to the instruction and control the motor speed.
3.protection mechanism: Equipped with overcurrent, overheating, and low-voltage protection functions.
3. Advantages of 4-in-1 ESC
Compared with traditional split ESCs, four-in-one ESCs have the following significant advantages:
| Comparative item | 4-in-1 ESC | Split ESC |
|---|---|---|
| Installation complexity | Low (integrated design) | High (requires independent installation) |
| weight | Lighter (fewer cables) | Heavier (more cables) |
| Response speed | Faster (short signal path) | Slower (signal delay) |
| Maintenance cost | Low (low failure rate) | High (many wearing parts) |
4. Recommendations for popular 4-in-1 ESC products
The following are the four-in-one ESC products and their parameters that have attracted much attention in the market recently:
| Product name | Maximum current | input voltage | weight | Features |
|---|---|---|---|---|
| T-Motor F55A Pro | 55A | 2-6S | 28g | Support BLHeli_32 firmware |
| Hobbywing XRotor 60A | 60A | 2-6S | 30g | Overheating protection |
| iFlight SucceX-E 45A | 45A | 2-6S | 25g | Compatible with DShot protocol |
5. How to choose a suitable 4-in-1 ESC
When choosing a 4-in-1 ESC, you need to consider the following factors:
1.Current demand: Select the matching current specification (such as 30A, 45A, 60A, etc.) according to the motor power.
2.voltage range: Commonly supports 2-6S (lithium battery voltage), which needs to match the battery.
3.Firmware compatibility: Give priority to products that support BLHeli_32 or AM32 firmware, with more adjustable parameters.
4.Thermal design: Metal shell or heat sink can effectively extend the service life.
6. Future development trends
With the popularity of traversing machine racing and FPV (first-person-view flight), four-in-one ESCs are developing towards higher integration and more intelligence. For example:
1.Integrate with flight control: Some manufacturers have launched an integrated “flight control + electronic control” solution.
2.AI adjustment: Automatically optimize the motor response curve through algorithms.
3.Over-the-air updates:Support OTA (over-the-air upgrade) firmware update.
As the core component of the ride-through machine, the technological progress of the four-in-one ESC will directly promote the performance improvement of the entire machine. Whether you are a novice or an experienced player, choosing a suitable 4-in-1 ESC can significantly improve your flying experience.
