Abstract
The utility model provides a spark-eliminating electric motor for the technical field of electric motors. The utility model is mainly characterized in that spark eliminating circuits are arranged on part or all the windings (armatures) of an electric motor, so that counter electromotive force, potential difference and induced potential generated when the electric motor is used can be weakened or eliminated to eliminate sparks. As a result, the service life of the electric motor can be extended. The utility model can be used at combustible and explosive places, and the working range is widened.
Description
The utility model belongs to technical field of motors, is a kind of antispark motor.
In existing technology, motor is as an inductive load, owing to reasons such as galvanomagnetic effects, when electric motor starting, stop or in servicely all may produce back electromotive force or potential difference etc., thereby cause producing spark, puncture winding, in the place that has flammable explosive gas, easier causing burnt and blast, exists insecurity.
The purpose of this utility model is a kind of antispark motor of design.
The technical measures that the utility model is taked are to connect arc-suppression circuit on all or part of winding of existing motor internal or armature, arc-suppression circuit comprises resistance, electric capacity, semiconductor diode, voltage stabilizing didoe, discharge tube, selenium pile, TVS Transient Voltage Suppressor, metal oxide arrester and series, parallel thereof or combinational circuit.
The utility model is owing to connected arc-suppression circuit on motor internal winding or armature, therefore can slacken or eliminate the back electromotive force that produces when motor uses, potential difference and induced potential, thereby elimination electric spark, improved the useful life of motor, can be used for existing the place of flammable explosive gas, widened range of application, compare with prior art and have significant advantage.
