Three-phase asynchronous motor can be divided into squirrel cage type and winding type two, the main difference is the structure of the rotor winding, winding asynchronous motor structure is more complex, generally used in starting and speed regulation performance requirements of the occasion, the following and Senforce motor Xiaobian together to understand the next.
About the squirrel cageThree-phase asynchronous motorWhen the squirrel cage rotor winding has no iron core, the shape of the entire winding is like a squirrel cage. There are also slots in the rotor core, each of which has a copper or aluminum guidance bar as the rotor conductor. The two ends of the guide bar are shorted with short circuit rings to form a closed loop. The large and medium-sized motor guide bar is copper, and the bare copper bar is inserted into the rotor core slot during manufacturing, and then the copper ring is placed on the head of the copper bar at both ends, and welded together;The lead bars of most small motors are made of aluminum, and the folded rotor core is placed in a cast aluminum mold, casting the cage and the inner fan at the end in one cast.
About the winding typeThree-phase asynchronous motorThe wound rotor winding is similar to the stator three-phase symmetric winding and is embedded in the rotor slot. The tail end of the three-phase winding is connected to the star inside, the head end is led from the center of the rotor shaft to the slip ring, the slip ring is connected to the external resistance through the brush, which can improve the starting and speed regulation performance of the motor. Some winding motors are also equipped with brush lifting device, after the start of the external resistance in the series, the brush is lifted, and the three-phase slip ring is directly short-circuited to reduce the loss in operation.
