In batch production, we often encounter this situation: sometimes different defects appear due to seemingly the same cause, and sometimes the same defect occurs due to different causes.
Back electromotive force is generated by opposing the tendency of the current in the winding to change. Back electromotive force is generated in the following situations: (1) when an alternating current is passed through the coil;
The characteristics of motor products are the relative stillness of the stator and the relative movement of the rotor during operation. Usually, we use the relatively still parts as the input or output of the power supply.
Deep groove ball bearings cannot bear heavy axial loads, so angular contact ball bearings (also known as thrust bearings) are mainly used as locating bearings in vertical motors.
In the production and manufacturing process of motors, in order to obtain some performance advantages of certain parts, thermal treatment processes are sometimes used. Different materials, different parts,
If you have had the opportunity to participate in the test of motors, you may have a deeper understanding of frequency conversion technology. Especially those who have experienced old test equipment can better feel the advantages of frequency conversion technology.
As for the bearings of motors, whether we are motor manufacturers or motor users, we all know that for heavy-loaded motors, cylindrical roller bearings will be used at the shaft extension end of the motor, and for particularl
