Marine type motor in the use of the process must consider its safety performance, at this time the wiring of the motor is very important, can not have any careless, so as not to cause hidden danger.

　　When wiring Marine motor, do not build any motor control circuit on winding or plug-in prototype board. It is very important to use high-frequency printed circuit wiring to prevent pulse dithering. Usually due to excessive noise at the input end of the current detection sensor or error signal amplifier. Therefore, the printed circuit layout shall have a ground surface with a small current signal and a high drive output buffer and shall be returned to the power input filter capacitor through separate paths.
