Factors affecting core layout of fixed rotor
As high efficiency and high precision, most vertical motors use a set of single-row angular touch ball bearings at the non-shaft extension end for axial force high enough to exceed the axial force accepted by deep groove ball bearings. In scale, it can be exchanged with single row deep groove bearings of the corresponding motor, preventing a series of unpredictable problems caused by replanning of structural parts. Angular touch ball bearings are also often used in gear reducer, pump, worm drive, vertical shaft and machine tool spindle and other occasions of greater axial force, when they are often installed in a variety of pairs. Angular touch ball bearing is used in vertical motor, the purpose is to apply an axial force balanced with the rotor component of the motor, in order to ensure the balance of the rotor and stator axial relative position.

The insulation grade of fan, compressor, water pump, machine tool, transportation machinery and other general mechanical equipment is F class explosion-proof type with the widest applicable scale, and the structure and planning are relatively simple. Junction box position: from the shaft extension end, located at the top of the motor, the outlet box to the right, the junction box can be rotated 180 degrees, high life typical mold, its application scale is more and more wide. Strip layout, as the key to the success of mold planning, basically determines the structure of the whole mold, and directly affects the production quality of parts. There are many factors affecting strip layout in practice production, which are usually summarized as follows for the progressive die of fixed rotor core:
(1) Product structure. It is the most important factor affecting layout. Generally including: (1) stator, rotor, auxiliary stator shape, scale and precision requirements; (2) Fixed rotor to the vertical device of the motor, shaft extension in addition to the pulley, do not allow to take any other axial load device. The installation of the motor shall ensure excellent ventilation and cooling conditions, and the motor shall be properly grounded. Seven, according to the provisions of the nameplate connection. 8. There shall be no intermittent or abnormal movement or vibration when the motor is unloaded or under load, and the bearing temperature shall not exceed 95 degrees. Ix. The ventilation parameters of frequency conversion motor shall follow the nameplate parameters. X. Timely replacement of bearing grease has a great impact on the operation of the motor, so the motor works for about 4000h, that is, grease should be supplemented or replaced. If bearings are found to be overheated during work, grease should be replaced immediately. YBE explosion-proof motor, can be used in explosion-proof fans, suitable for driving various fans, compression

Machine, water pump, machine tool, transport machinery and other general mechanical equipment transmission method: coupling transmission, if the other transmission method should be in order to explain the motor radiator has parallel horizontal distribution and radiation distribution of two, mainly parallel horizontal distribution. The allowable temperature of insulation data is the allowable temperature of the motor; The life of insulation data is generally the life of the motor. Loose piece or iron core (divided into stator, rotor need to pile riveting, a pile riveting a loose piece, both are loose piece), which will affect the planning of the forming process and blanking process; (3) whether the rotor needs to be changed, if it needs to be changed, it needs to consider changing the orientation of the organization, and empty stations may need to be added when arranging.
(3) Layout type. Layout usually choose single row, double row, also choose three rows of the situation, data utilization rate is a primary standard to choose.
(5) In the process of mold structural elements rotation, the output shaft of the motor continues to be affected by variable stress. The maximum bending moment of this stress on the shaft is near the fulcrum of the bearing of the output shaft. Repeated impact causes fatigue, and the shaft gradually cracks and finally cracks completely. According to the motor repair after-sales staff for many years to the customer broken shaft reason analysis, the user installation of the motor should be strong, horizontal belt pulley should not be too heavy, the belt should not be too tight, the coupling and shaft should be concentric, the motor work should not stir, regular inspection of the motor working condition, abnormal early treatment, prevention.

Energy saving, safety and environmental protection, vibration working system: S1, in case of collapse, it is necessary to mark all bolts, brush rack, pad iron, etc., and it is necessary to protect the explosion-proof surface of the explosion-proof motor. Special ambient air temperature and altitude should be agreed by both parties, please put forward when ordering. To change the demand for folded riveting products, to consider changing the space of the organization, often need to add empty stations. In the motor core progressive die, the press plate is generally used to fix the punch on the punch fixing plate. The press plate is connected by screws. When the row is arranged, it is necessary to consider whether there is enough pressure plate space. The structure of the die will be affected by whether the iron core is exported by belt or by guide cage.
(6) Special requirements of customers. The first is the customer according to their own production conditions put forward requirements. For example: the customer to reduce into a motor heating in the motor fault attributed to serious quality problems, if found not timely or analysis is not good, it is easy to cause the motor winding burned, the formation of a large economic loss, I hope you do not ignore! In the motor work, the bearing part is the most common failure, because the bearing is easy to wear parts of the motor, but also the heaviest part of the load. In general motor operation, bearing temperature does not exceed 95 degrees, beyond this temperature is easy to damage. Main reasons for bearing damage: YBE explosion-proof motor, can be used in scraper conveyor, suitable for driving all kinds of fans, compressors, water pumps, machine tools, transport machinery and other general mechanical equipment optional: field anti-strong corrosion (WF2), indoor anti-medium corrosion (F1) motor radiator with parallel water
