Frequently Asked Questions

Is this cable suitable for 3-phase BLDC thruster motor wiring on ROVs?

Yes. This is one of the most common applications for 3 x 18AWG screened cable. The 3 conductors carry the U, V, W phases from the ESC to the thruster motor. The individual screening and overall shield minimise PWM switching noise that could interfere with subsea sensor signals.

Can the screening drain wires be connected at the ESC end?

Yes. For motor drive applications, drain wires should be connected to the ESC chassis ground at one end only. Floating the drain wire at the motor end prevents ground loops while still providing effective EMI suppression of motor switching transients.
