FAQ
What is the role of the frame in the motor?
The main load of the frame during the operation of the motor
(1) Gravity load, generally the weight of the stator. In the motor with end cover bearing, the weight of the rotor is also supported, while in the suspended hydro-generator, the weight of the rotating part of the unit, the upper frame, etc. needs to be supported.
(2) The radial force caused by the unilateral magnetic pull and the thermal expansion of the iron core.
(3) In the case of internal press-fitting and full-circle punching, some parts of the machine base must bear the axial rebound force of the iron core; for the suspended hydro-generator, it must bear the axial water thrust.
(4) Torque. Including the transient electromagnetic torque when the load suddenly changes and the generator is suddenly short-circuited. Among the above loads, torque is the most important. In addition, the frame of a general motor will also be subjected to clamping force, cutting force, lifting force, etc. during processing, transportation, and installation; for motors that require sealing (such as hydrogen-cooled steam turbine generators or explosion-proof motors), the The machine base is also subjected to the action of test pressure. When the end cover bearing and belt (or gear and other transmission mechanisms) are used for transmission, the machine base and its feet will also be subjected to the action of the belt pulling force (or the force of the gear and other transmission mechanisms). . Therefore, when designing the machine base, the mechanical calculation of the general machine base often includes the calculation of its stiffness, strength and natural vibration frequency. The strength calculation of the joint plate bolts needs to be carried out for the half machine base, and the foot plate welding seam needs to be carried out for the welding machine base. The calculation of stress, which is mainly the calculation of the stiffness of the machine base.
