Three-phase induction motor(Triple-phase asynchronous motor)Its by simultaneous access380VThree-phase AC power supply(Phase difference120The degree of)A type of electric motor supplied with electricity,Because the rotor and stator of the three-phase asynchronous motor rotate the magnetic field in the same direction、Different speed into rotation,There is a slip,So its called three-phase asynchronous motor。 When the motors three-phase stator winding After the three phase symmetrical alternating current,Will create a rotating magnetic field,The rotating magnetic field cuts the rotor windings,Thus an induced current is generated in the rotor winding(The rotor winding is a closed path),The rotor conductor carrying current will generate electromagnetic force under the action of stator rotating magnetic field,Thus forming electromagnetic torque on the motor shaft,Drive motor rotation,And the direction of the motor rotation is the same as that of the rotating magnetic field. When a conductor cuts a line of f

Temperature relay switch symbol Temperature relay;The product is a contact induction sealed temperature relay,Have small size、Light weight、High temperature control precision,Extremely versatile。Is used for a wide range of products,Aerospace availability、Surveillance camera equipment、Electric machine、Electrical equipment and other industries for temperature control and overheat protection。Many drawings are made with symbols instead of Chinese to make the drawings look beautiful and more professional,The following Feng Ye Xiaobian will take you to take a look at the temperature relay switch symbol。
fagDeep groove ball bearing model FAGDeep groove ball bearing formerly known as single row radial ball bearing,Is widely used A kind of rolling bearing。It is characterized by low friction resistance,High speed of revolution,Can be used to withstand radial loads or diameters On a joint load that acts simultaneously in both direction and axial direction。Compared with words, pictures can often make people clearly understand the general meaning,The following Feng Ye Xiaobian will take you to understandFAGDeep groove ball bearing model drawing。
TIMKENCylindrical roller bearingsIts a bearing,It is characterized by large radial bearing capacity,The application is large and medium-sized motor、Rolling stock 。 principle: Single row cylindrical roller bearings are usually subject to radial forces only,Compared with ball bearings of the same size,Radial bearing capacity increased1.5-3times,Good rigidity、Impact resistance,It is especially suitable for rigid supports、It also supports the short shaft、Axial displacement of shafts caused by thermal elongation and installation and disassembly of machine accessories requiring separate type bearings。Mainly used for large motor、Machine tool spindle、Engine rear and rear support shafts、Train car axle support、Diesel crankshaft、Car tractor gearbox, etc。
Deep groove ball bearing means that the inner and outer ring with a groove,The rolling element is the ball,Generally divided cage and full ball two
