Abstract

The invention discloses a DC motor. The DC motor is applied to a nuclear-level valve electric executing mechanism, comprising a motor seat, a shaft extending end cover and a reverser end cover, wherein the shaft extending end cover is of a single-layer end cover structure and arranged at one end of the motor seat; the reverser end cover is of a double-layer end cover structure and arranged at the other end of the motor seat. According to the DC motor, the reverse end cover is of the double-layer end cover structure through which the structure and sealing requirements of the DC motor are ensured, and meanwhile, the testing, debugging, use and maintaining processes of the DC motor are conveniently performed; the special requirements of a nuclear power environment can be further met, and the protecting grade is high.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a DC motor applied to an electric actuator of a nuclear-level valve. Background technique [0002] Under the background that all countries in the world have put forward higher requirements for nuclear power safety and re-analyzed the reliability of nuclear power device actions, my country has begun to independently develop third-generation nuclear power technology and improve electric devices. One of the improvements is to use DC Electric motors instead of AC motors. [0003] In the prior art, the end cover of the DC motor commutator has a single-layer structure, which cannot meet the requirements of convenient DC motor test debugging, use and maintenance on the basis of meeting the structure and sealing requirements of the DC motor. Contents of the invention [0004] The invention provides a DC motor applied to an electric actuator of a nuclear-level va...
