Answer:Servo control technology is necessary to determine the position of the motor. This chapter will introduce the principles of servo control. We will also introduce the application of programmable servo/sequence controller (PSC) in servo control.
Answer:Bore scraping is a mechanical quality failure that motor products often encounter. Its limit state is uneven air gap , that is, the motor stator and rotor are not coaxial. Uneven air gap is a defect that the physical space of motor parts does not con...
Answer:There are actually many aspects to judge the quality of an electric motor. Today, the editor has sorted out a few points and hopes that it will be helpful to everyone.
Answer:Motor bearings are also called motor bearings or motor bearings. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, spherical bearings and oil-containing bearings. What is the temperature standard of ...
Answer:The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding induces electromotive force and current due to the relative motion between the rotor winding and the magnetic field...
Answer:permanent magnet motors are becoming more and more popular in many modern industrial applications, such as electric vehicles, wind power generation, industrial automation equipment, etc. However, permanent magnet motors also have some limitations, su...
Answer:AC asynchronous motors are electric motors that run on leading AC voltage and are widely used in household appliances such as electric fans, refrigerators, washing machines, air conditioners, hair dryers, vacuum cleaners, range hoods, dishwashers, el...
Answer:The windings of the motor can be divided into concentrated windings and distributed windings. In case of distributed windings, the winding is always wound on at least two stator teeth. On the other hand, in case of concentrated windings, only one sta...
Answer:Motors can provide power for many devices, which shows that motors must have enough application scenarios in real life. In order to enhance everyone's understanding of motors, this article will introduce the advantages and disadvantages of induc...
Answer:Asynchronous motors are also called induction motors because the rotor current of asynchronous motors is generated by electromagnetic induction.
