We often get the question of whether an ESC is always required, even if controlling the
speed or the direction of a thruster is not desired. The answer is yes, an ESC is always
required. At the core of a thruster is a brushless DC (BLDC) motor. Like any other BLDC
motor, an ESC is required to energize the motor phases at the correct timing to drive the
motor. If you try to use a thruster like a common brushed motor, you will just end up with a
broken thruster.

The thruster cable has three conductors that terminate in tinned wire ends.
