Abstract

The invention discloses an induction motor rotor fault quantitative simulation experiment device. Comprising an experiment bench, a rotor lead-out induction motor and a control cabinet. In the lead-out induction motor, a rotor mouse cage conducting bar is fixed in a groove of a rotor core, and two ends of the rotor mouse cage conducting bar are respectively arranged in two end ring open grooves at two ends; a leading-out type screw hole is formed in one end of each mouse cage guide bar, a binding post is installed in each screw hole, direct short circuit and non-direct short circuit of the mouse cage guide bars at the position of the end ring B are achieved through conductive and non-conductive nuts which are arranged on the binding posts and make contact with the end ring, and a plurality of mouse cage guide bars can be led out through the sliding ring and connected with a control cabinet. According to the invention, the blank of the special experimental device for fault simulation of the induction motor rotor is filled, the broken bar simulation process is simplified, the short circuit of the rotor to the ground caused by burrs generated by processing is avoided, the repeatable quantitative simulation of different broken bar fault conditions is realized, and the convenience and expandability of the fault test of the induction motor rotor are improved.

Description

technical field [0001] The invention relates to a comprehensive experiment device for motor faults, in particular to a quantitative simulation experiment device for induction motor rotor faults. Background technique [0002] As a driving device, induction motors are widely used in national defense construction, industrial production, transportation, infrastructure, agricultural development, and daily life because of their convenient manufacture, low price, excellent performance, and ease of use. At present, induction motors are the motors with the largest consumption and the widest coverage in the world. Therefore, prolonging the service life of asynchronous induction motors, thereby improving the reliability and stability of the entire production system has become the top priority of industrial development. [0003] Induction motors are affected by factors such as power supply, load properties, operating mechanism, and installation environment. During operation, the fault f...
