When working with electricity, especially in water, always practice caution. Always ensure that connections are secure and watertight. Keep your body away from spinning motors and propellers.
1. Connect the three motor wires to the motor. The order of connections does not matter; however, switching any two wires will change the direction of the motor. The output phases A, B, and C are completely interchangeable.
2. Connect the red power wire and black ground wire to a power source like a battery. You will hear three beeps in rising pitch from the motor indicating all three phases are connected.
3. Connect the signal cable to your signal source like a RC radio receiver or microcontroller board. The white wire is the signal wire.
4. Send a stopped signal (1500 microseconds) for a few seconds to initialize the ESC. You will hear two tones indicating initialization, and then you can send a signal from 1100-1900 µs to operate the thruster. 1500 – 1900 µs for forward thrust, 1100 – 1500 µs for reverse.
Installation and Thermal Considerations
Like all ESCs, the Basic ESC can generate a significant amount of heat when operated. It’s important to consider this when mounting and operating the ESC to ensure that it is not damaged by overheating. Most of the heat is generated in the MOSFETs, which are underneath the blue aluminum heat spreader. Here are a few helpful tips:
1. If possible, make sure the heat spreader is exposed to free air or attached to a larger heat sink.
2. Do not use any adhesives that may insulate the heat generating components, such as silicone sealant.
