4. การตั้งค่าและการติดตั้ง
การติดตั้งอย่างถูกต้องเป็นสิ่งสำคัญอย่างยิ่งต่อประสิทธิภาพและความปลอดภัยสูงสุด โปรดปฏิบัติตามขั้นตอนเหล่านี้อย่างระมัดระวัง:
- การติดตั้ง ESC: Securely mount the EZRUN 18A ESC in your vehicle using double-sided tape or screws. Ensure it has adequate airflow for cooling.
- การติดตั้งมอเตอร์: Install the EZRUN 12T/2030 motor into your vehicle's motor mount. Ensure proper gear mesh between the motor pinion and the spur gear.
- การเชื่อมต่อมอเตอร์เข้ากับ ESC: Connect the three motor wires to the corresponding three wires on the ESC. While specific order is not critical for sensorless motors, maintaining consistency (e.g., A to A, B to B, C to C) is good practice. If the motor spins in the wrong direction, you can reverse two of the motor wires or adjust the motor rotation setting via the program card.
- การเชื่อมต่อ ESC กับตัวรับสัญญาณ: Plug the ESC's throttle cable (usually a black, red, and white wire bundle) into the throttle channel (typically Channel 2) of your RC receiver.
- การเชื่อมต่อแบตเตอรี่: Connect your battery pack to the ESC's battery input wires. Ensure correct polarity (red to positive, black to negative). Incorrect polarity can cause severe damage.
- Radio System Setup: Turn on your transmitter, then turn on the ESC. Calibrate the ESC to your radio system's throttle range according to the ESC's specific calibration procedure (refer to the general Hobbywing ESC manual if not detailed here). This typically involves holding the throttle at full, neutral, and full reverse during power-up.
5. Programming with the LED Program Card
The included LED Program Card allows for easy adjustment of various ESC parameters. Connect the program card to the ESC's fan/program port (if available) or the throttle cable port (after disconnecting from the receiver) and power the ESC. The card will display the current settings, which can be changed using the "ITEM" and "VALUE" buttons.

6. คู่มือการใช้งาน
- เปิดเครื่อง: Ensure all connections are secure. Turn on your radio transmitter first, then connect the battery to the ESC. The ESC will emit a series of tones indicating successful power-up and cell count detection.
- การขับขี่: Use the throttle trigger on your transmitter to control the vehicle's speed and direction. Gentle throttle inputs are recommended initially, especially with high-power systems.
- หมดแรง: Disconnect the battery from the ESC first, then turn off your radio transmitter. This sequence prevents accidental throttle inputs.
- การติดตาม: Pay attention to the temperature of the ESC and motor during operation. If either component becomes excessively hot, stop operation and allow them to cool. Adjust gearing or ESC settings if overheating is a recurring issue.
7. การบำรุงรักษา
- การทำความสะอาด: Regularly clean the ESC and motor to remove dirt, dust, and debris. Use a soft brush or compressed air. Avoid using liquids directly on electronic components.
- การตรวจสอบ: Periodically inspect all wires and connectors for damage, fraying, or loose connections. Ensure motor bearings are smooth and free of resistance.
- พื้นที่จัดเก็บ: When not in use, store the ESC and motor in a dry, cool place away from direct sunlight and extreme temperatures. Disconnect batteries when storing.
- อัพเดตเฟิร์มแวร์: ตรวจสอบที่ Hobbywing website for any available firmware updates for your ESC. Updates can improve performance and add new features.
