Prevent the casing from leaking electricity? Very few motors I’ve seen are grounded; in the 3+1 configuration, the 1 terminal is almost always cut off
It is to prevent harm to the human body in case of electric leakage from the motor
Prevent insulation failures that could lead to electric shock for personnel
The purpose of installing a grounding wire for the motor is to prevent electric shock in case the insulation of the motor’s windings is damaged and leakage occurs; touching the metal casing in such a situation could lead to an electric shock. The grounding wire serves to direct the leakage current back into the ground, thereby returning it to zero. This creates a loop. To ensure personal safety,
Fill-in-the-blank: The purpose of installing a grounding wire for motors is (to introduce charges into the ground so that they can return to zero)
Installing a ground wire is to direct any leakage current back into the earth via the ground wire, thereby returning it to zero.
The purpose of installing a grounding wire for the motor is to (channel charges into the ground through the grounding wire so as to return them to zero)
The purpose of installing a grounding wire for the motor is to (channel charges into the ground through the grounding wire so as to return them to zero)
The purpose of installing a grounding wire for the motor is to provide protective grounding that prevents electric leakage caused by faults or insulation damage in the motor, thereby protecting equipment circuits and preventing electric shock to people. In other words, motor grounding serves as a means of preventing electric shock in case of leakage, as well as electrical fires resulting from damaged circuits
