A new-type theory and method for motor protection |
| |
| Abstract: | This paper points out the basic new technological theory for motor- protection, and on the base of this, it also points out the new method for motor- protection. Through on-line measurement of direct current resistance of motors winding, it can determine the real rising temperature of motors. By comparing it with the winding resistance under the permitted highest temperature, it outputs alarming signal for cutting off the electricity supply, thus achieving the goal for protecting the motors effectively. |
