What is a Motor Shaft?

The main component in most rotating devices is the motor shaft. A shaft is a mechanical section for transforming the rotation and torque. Shaft size significantly influences the torque in these devices. Therefore, the precise modeling and prototyping of shafts are essential for all applications.

In addition to the need for mounting the rotor and a variety of attachments, the model of the motor shaft is very much based on the cooling concept selection of the electric device. Particularly with greater electric motors and thus longer and larger motor shafts, a hollow shaft enables new model matters both for lightweight construction and for the cooling system.
Some different performances are used to resume the transmission of the torque from electricity to the kinetic output in the transmission and thus to move the device. Based on the great rotation speed of up to more than 20.000 rpm and the large torques, the motor shafts should tolerate very high loads. This needs high-strength parts that still have to meet high requirements for lightweight modeling.
