How to connect brushless motors in mode aircraft
Among model aircraft enthusiasts, brushless motors have become the mainstream power choice due to their advantages such as high efficiency, long life and low noise. However, wiring of brushless motors can be a confusing problem for beginners. This article will introduce in detail the wiring methods of brushless model aircraft wires and provide relevant data references to help you quickly master wiring skills.
1. The basic structure of brushless motors
Brushless motors usually consist of two parts: stator and rotor. Three sets of coils (three-phase) are wound on the stator, and the rotor is equipped with permanent magnets. The brushless motor controls the phase of the current through an electronic speed regulator (ESC), thereby driving the motor to rotate. The wiring of brushless motors mainly involves the connection between the motor three-phase wire and ESC.
| Motor wire color | ESC output line | Connection instructions |
|---|---|---|
| Red (Phase A) | ESC Phase A | Usually corresponding to the U phase marked by the motor |
| Yellow (Phase B) | ESC Phase B | Usually corresponding to the V phase marked by the motor |
| Blue (Phase C) | ESC Phase C | Usually corresponding to the W phase of the motor mark |
2. Wiring steps
1.Confirm the phase correspondence between motor and ESC: Different brands of brushless motors and ESCs may have color marking differences. It is recommended to consult the product manual or determine the phase correspondence through experiments.
2.Connect the motor to the ESC: Connect the three-phase wire of the motor (usually red, yellow, and blue) to the three-phase output wire of the ESC. If the motor is reversed, the wiring of two phases can be exchanged arbitrarily.
3.Connect ESC to battery: The ESC power cord (usually red and black wires) is connected to the positive and negative electrodes of the battery, be careful not to reverse the polarity.
4.Test motor steering: After power on, test the motor steering through the remote control. If the direction is wrong, readjust any two phases of the motor and ESC.
3. Frequently Asked Questions and Solutions
| question | Possible Causes | Solution |
|---|---|---|
| The motor does not turn | Wiring error or ESC not initialized | Check wiring and recalibrate ESC |
| Motor reversal | Phase inverted | Switch any two-phase connection |
| Motor shake | ESC does not match the motor | Replace matching ESC or adjust ESC parameters |
