[0002] The motor shaft is generally made of high-quality carbon steel. You can choose 35# or 45#. Generally, 45# steel is used. These two materials belong to medium carbon steel, and their strength, rigidity, and toughness can meet the working requirements of the motor shaft. The motor shaft has a high speed and low torque. It is made of 45# and does not require other heat treatment. The raw materials are in normalized state. The supply performance of the raw materials can meet the mechanical performance requirements of the motor shaft;

[0003] After checking the public (announcement) number: CN217143484U, a motor shaft rust removal device for brake motor manufacturing is disclosed. This technology discloses "a motor shaft rust removal device for brake motor manufacturing, including a frame device for supporting and grinding the motor shaft, a driving device for pressing down and driving the motor shaft to rotate is installed on the top of the frame device, a clamping device for clamping the motor shaft is arranged below the driving device, and a translation device for reciprocating movement is arranged below the clamping device" and other technical solutions, which have "the setting of pressing and holding by the transmission belt ensures the rust removal of the motor shaft rotation; the symmetrical setting of the grinding roller speeds up the support and speed of the motor shaft rust removal; the reciprocating movement setting ensures the comprehensiveness of the motor shaft rust removal" and other technical effects;
