Common types of armature shaft (I)

armature shaftIt is an important part of the motor equipment. The armature shaft serves as the link between the motor and the equipment, supporting the rotating parts, transmitting torque and determining the relative position of the rotating parts. Therefore, the armature shaft must have high strength and rigidity.

The motor is different, the usearmature shaftIt is not the same, the armature shaft can be divided into many types, the following specific introduction of the common classification of the armature shaft.

1.armature shaftAccording to the classification of whether there are steps above, it can be divided into stepped armature shafts and non-stepped armature shafts. Non-stepped armature shafts are also called optical axes. Optical axes are generally made of cold-drawn round steel and can be used in micro-motors. Stepped armature shafts can be equipped with different parts more conveniently and reliably, so they are currently widely used.

2.armature shaftAccording to the production process can be divided into round steel shaft, forging shaft, welding shaft. Round steel shaft is common in small and medium-sized motors, and the armature shaft is generally made of high-quality carbon structural steel. The welding shaft uses radial ribs instead of the rotor support, which increases the ventilation area of the rotor, but it is agreed to cause deformation during welding, so annealing treatment is required after welding.

3.armature shaftAccording to the shape of the shaft center, it can be divided into a solid shaft, a shaft with a deep hole at one end and a shaft with a central through hole. Solid shafts are more common, but deep-hole shafts are generally used in wound asynchronous motors to facilitate the lead wire on the rotor through The hole is connected with the collector ring outside the end cover.

The above is a summary of the common classifications of armature shafts, and there are other classifications that have not been summarized,Fuzhou Sanhe Precision Shaft Co., Ltd.Specializing in the production of various types of armature shaft, precision shaft, micro shaft, etc., the product has been recognized by the market, welcome to inquire.
