Servo motorThe inner rotor is a permanent magnet，Driver controlledU/V/WThree-phase electricity forms an electromagnetic field，The rotor rotates under the action of this magnetic field，At the same time, the encoder with the motor feeds back the signal to the driver，The drive compares the feedback value to the target value，Adjust the rotation Angle of the rotor。 1、Permanent magnet AC servo motor has the following advantages： （1）The motor has no brush and commutator，Work reliably，Simple maintenance and maintenance； （2）The stator winding dissipates heat quickly； （3）Low inertia，Easy to improve the speed of the system； （4）Suitable for high speed and high torque working state； （5）At the same power，Small size and weight，Widely used in machine tools、Mechanical equipment、Handling mechanism、Printing equipment、Assembly robot、Processing machinery、High speed winding machine、Textile machinery and other occasions，To meet the development needs of the transmission field。
Micro DC motor features： 1.Micro DC motors are generally more efficient than other types of motors，So you get the same output power，The volume of DC motors is generally relatively small。For a limited installation location，Micro dc motorRelatively suitable。 2.The micro DC motor has a feature that the motor can be based on the load size，Automatic deceleration，To achieve extreme starting torque。This AC motor is more difficult。In addition, the DC motor is easier to absorb the sudden change of load size，The motor speed can automatically adapt to the load size。
Alignment of the coupling，In four steps。Now let me elaborate。
It is well known that，Bearing in case of damage，It is necessary to go through a very rigorous testing process to determine whether the damaged bearing can be repaired。Bearings to be repaired must be thoroughly cleaned，And then very rigorous, comprehensive testing。The first is to detect the bearing only damage，If there are cracks、Large peeling and overheating discoloration，Bearings with these injuries are likely to be beyond repair and must be scrapped。
EZOImported bearingParts in heat treatment，There are thermal stress and structural stress，These internal stresses can be superimposed on each other or partially offset，Is complex and changeable，Because it can follow the heating temperature、Heating rate、Cooling mode、Cooling rate、Parts vary in shape and size，So heat treatment deformation is inevitable。Understanding and mastering its changing laws can makeEZODeformation of imported bearing parts（Like the ellipse of a ring、Size increases, etc）Keep it under control，Conducive to production。Of course, the mechanical collision in the heat treatment process will also cause the parts to deform，But this kind of deformation can be reduced and avoided by improving operation。
The occurrence of Siemens inverter failure is very many，This is also one of the faults that commonly exist in the operation of all kinds of inverters。So how do we reduce the occurrence of inverter failures？This is a problem that all inverter manufacturers and users are very concerned about。Lets give you a specific introduction！
Omron relays are capable of producing a small current for the draw and close action。In normal use，The given current must be slightly greater than the draw current，So the Omron relay can work stably。And the operating voltage applied to the coil，Generally do not exceed the rated operating voltage1.5times，Otherwise, it will generate a large current and burn the coil。
The advantages of Maiyudi synchronous belt drive
normal，If bearings are used correctly，Can be used until fatigue life is reached。But there will be accidental premature damage，Incapacitated for use。This early damage，Relative to fatigue life，Is a quality limit called a failure or accident。Many causes are installation、Use、Careless lubrication，A foreign body invading from the outside，Counter axis、The thermal effect of the shell is not sufficiently studied。
Formation mechanism of grinding metamorphic layer on working surface of Kentie flange bearing，The main factors affecting the grinding metamorphic layer are grinding heat and grinding force。Below we will analyze the reasons for the heating of Ken iron flange bearings！
