DC motor is a rotating motor that can convert DC electric strength into mechanical power (DC motor) or mechanical strength into DC electric powered vitality (DC generator). It is a motor that can change DC and mechanical vitality into a single yet another. When it operates as a motor, it is a direct present motor, which converts electrical vitality into mechanical strength when it operates as a generator, it is a direct existing generator, which converts mechanical strength into electrical strength.
|Item Identify||Fired up DC Motor for Drilling in ZJ500-one thousand Oilfield|
|Motor Type||DC Motor,ACMotor,Stepper Motor,Asynchronous Motor ,Synchronous Motor
|Composition construction||The framework of DC motor must consist of two parts: stator and rotor. The static component of DC motor is referred to as stator. The major purpose of stator is to make magnetic area, which is composed of foundation, main magnetic pole, commutation pole, finish cap, bearing and brush device. Working portion is named rotor, whose main perform is to create electromagnetic torque and inductive electromotive force. It is the hub of vitality conversion of DC motor. So it is also generally known as armature, which consists of rotor, armature main, armature winding, commutator and fan.|
|Torque variety||one.five ~180kNm|
|Safety amount||IP23, IP44|
|Operating speed||Constant Velocity /Low Pace /Adjust Speed /Large Speed Other|
|Main classification||DC Motor is a machine that converts mechanical strength into DC electricity. It is primarily utilized as DC motor for DC motor, electrolysis, electroplating, smelting, charging and excitation electrical power source of alternator. Though in locations in which DC electricity is essential, AC energy rectifier is also utilised to convert AC into DC electricity, but from some factors of functionality, AC rectifier energy offer can not totally exchange DC generator.|
|Software||DC motors are commonly utilised in tape recorders, online video recorders, video discs, electrical shavers, hair dryers, digital watches, toys and so on.|
|Routine maintenance method||Skilled motor upkeep heart motor upkeep approach: cleansing stator and rotor – replacing carbon brush or other areas – vacuum F strain dipping paint – drying – Calibration stability.
one. Use atmosphere must be constantly dry, motor surface ought to be kept cleanse, air ingestion should not be hindered by dust, fibers and other obstacles.
two. When the thermal safety of the motor proceeds to operate, it must be ascertained no matter whether the fault comes from the motor or the overload or the placing benefit of the protecting gadget is also lower. Soon after reducing the fault, it can be place into procedure.
3, guarantee that the motor is well lubricated throughout operation. The general motor runs for about 5000 several hours, that is to say, lubricating grease ought to be extra or replaced. When bearing overheating or lubricating deterioration is located in operation, the hydraulic pressure ought to adjust lubricating grease in time. When replacing grease, the previous grease should be eliminated, and the oil groove of bearing and bearing include need to be washed with gasoline. Then ZL-3 lithium grease must be loaded with one/two (two poles) and two/three (four poles, six poles and 8 poles) of the cavity in between the interior and outer rings of the bearing.
four. When the existence of the bearing is over, the vibration and noise of the motor will improve clearly. When the radial clearance of the bearing reaches the following worth, the bearing ought to be changed.
5, when getting rid of the motor, it is Okay to remove the rotor from the shaft extension or the non extension finish. If it is not needed to unload the enthusiast, it is more practical to just take out the rotor from the non-axle extension end. When pulling out the rotor from the stator, the stator winding or insulation should be prevented from currently being damaged.
6. When changing the windings, the sort, dimensions, turns and gauges of the first windings need to be recorded. When these data are lost, they need to be acquired from the manufacturer and the authentic developed windings need to be altered at will, which usually deteriorates one particular or numerous efficiency of the motor or even tends to make it extremely hard to use them.
