Energy-saving remanufacturing technology of brushless dc motor | brushless dc motor of high efficient remanufacturing technology | | brushless dc motor, brushless dc motor in the south of anhui

Takeaway: brushless dc motor in the south of anhui energy-saving remanufacturing, brushless dc motor is the inefficient brushless dc motor by redesigning, replacement parts, and then made into high efficiency brushless dc motor or apply to specific load and condition of system energy saving brushless dc motor (Change pole brushless dc motor, frequency conversion brushless dc motor, permanent magnet brushless dc motor, etc. )。 As efficient promotion of brushless dc motor and brushless dc motor system energy saving reconstruction work, eliminated down inefficient brushless dc opportunity more and more. How to deal with the old brushless dc motor is inevitable problems, if the brushless dc motor after simple renovation again into the market, will lead to government subsidies for efficient brushless dc motor, the other side of the inefficient old brushless dc motor is back into the market situation, to promote efficient brushless dc motor and brushless dc motor system energy-saving work serious adverse, so the inefficient old efficient remanufacturing of brushless dc motor is the inevitable requirement of the national energy conservation and emissions reduction work. Below, the brushless dc motor in the south of anhui took everybody understand the brushless dc motor manufacturing to a process. Remanufacturing process for brushless dc motor: old pieces of assessment of detection and classification, determine the remanufacturing scheme, and dismantling of every parts and components manufacturing (The stator, rotor, end cover, fan, wind hood, junction box), assembly, factory test. Stator, the stator coil by impregnating varnish and curing of the stator core as a whole, it is often hard to take apart, in the brushless dc motor repair of the past, adopt the method of burning coil varnish, remove damaged core quality, pollution to the environment; Remanufacturing adopts special machine tool cutting winding end, nondestructive and pollution-free. After cutting winding ends, using hydraulic pressure equipment out of the coil of the stator core, core after heating, the pull of the stator coil, winding coil according to the new plan. To logoff after cleaning, the stator core, connection, pressure test, after passing into the VPI varnished varnished, into the oven to dry after varnished. Rotor: adopts hydraulic rama, remove the bearing; Rotor core and USES the interference fit between a shaft, in order not to damage shaft and core, remanufacturing adopted the intermediate frequency eddy current heating equipment for heating of brushless dc motor rotor appearance, according to the shaft and rotor core heat expansion coefficient is different, separate shaft and rotor core. Rotating shaft for processing, using medium frequency eddy current heating heater rotor core, pressure into the new shaft. Rotor after the completion of the installation on the dynamic balancing machine to do dynamic balance test, the bearing heater heating bearing, installed on the rotor. Stand, end cover: stand, end cover, after inspection, the sand blasting equipment clean appearance, to use fan, wind shield: the original parts scrap, new high efficiency fan, wind shield. Panel: junction box cover, wiring board scrap, to purchase. According to the new BLDC motor manufacturing way to final assembly, factory test.
