Difference between inner rotor brushless motor and outer rotor brushless motor

Posted by Fengyukun on

Difference between inner rotor brushless motor and outer rotor brushless motor
The choice between an inner rotor and an outer rotor brushless motor depends on the specific requirements of the application. Inner rotor motors are favored for their compact size and rapid response, while outer rotor motors excel in providing high torque and continuous operation.

ROV design—— ballast buoyancy control

Posted by Fengyukun on

When designing an ROV, it is common to use light weight components to keep the entire submersible from exceeding the desired weight limit, so aluminum or other lightweight materials are used. The weight of the submersible consists primarily of the following components: subsystem components, loads, and the buoyancy system used to establish the desired operational specific gravity.

How can I use a Raspberry Pi 4B to send a PWM signal to an ESC to control an underwater thruster?
The neutral stop signal is its unlocking signal
Using a 50Hz signal, the signal period is 20ms.
The percentage in the instructions refers to the percentage of the PWM control pulse width, not the actual duty cycle of the PWM signal (it is easy to misunderstand here).

【Underwater Thruster Control】 How to control ESC by PWM with STM32?

A lot of researchers who want to control the operation of the thruster with a microcontroller to find a lot of information on the Internet, but found that a lot of them are not written very clearly, APISQUEEN roughly record how to solve.I hope you can exchange experience in the comments section, can help more people.We buy the ESC may be different, but the overall control idea is the same, so I believe you can certainly achieve your goal after reading this article. PWM signal:(1) PWM wave control (generally speaking ESCs are controlled by PWM wave at 50Hz, that is...
