1, the damage of rectifier module is usually caused by power grid voltage or internal short circuit. Under the condition of eliminate water pump internal short circuit, replace the rectifier bridge. At the scene to deal with generator price failure, verify the user AC motor should focus on power grid, such as power grid voltage, whether of power grid pollution equipment such as electric welding machine, etc. 2, the inverter module or cable damage and the damage is electric water pump usually due to motor drive circuit failure cause. After repair www.facebook.com/guohong.trading of drive circuit, good condition, the measured waveform change module. After replacement driver board in the on-site service, but also must pay attention to check the motor and connecting cable. Without any fault is decided, the operating frequency converter.

3, ac synchronous generator electricity without display is commonly due to damage or soft charging circuit switch power supply damage caused no dc dc, such as starting resistance is damaged, it is possible that the single phase induction motor panel damage. 4, after power on display over voltage or under voltage due to the input phase, general circuit aging and circuit board to ac synchronous generator be affected with damp be affected with damp. Find out the voltage detection circuit and check points, to replace the damaged parts. 5, after ac motor power on display over current or grounding short circuit is generally due to the damage of electric current detection circuit. And such as hall element. 6, start the display over current is usually caused by inverter module drive circuit or damaged. 7, no-load output voltage is normal, after the loading of overload or over-current
Since the MANNESMANN spare parts Rexroth Indramat arm of company officially motor parts launched at the hannover 1978 trade fair MAC permanent magnet ac servo motor and drive lamination machine system, this symbolized this new generation of ac servo technology has entered the stage of practical application. By the 1980 s, generator the company has a complete series of products. The whole servo device market turned to the ac system. Early simulation systems such as zero drift, anti-interference and reliability, accuracy and flexibility, as well as insufficient, is not fully electric motor parts meet the requirements of motion control, in recent years as the wholesalemotor.blogspot.com microprocessor, the application of new type digital signal processor (DSP), diesel generator a digital control system, the control part can be completely by the software, called 摪 oboro creepy-crawlies or tuan continuous fresh synchronous generator Xi, 撊 creepy-crawlies permanent magnet ac servo lamination machine system. So far, the electrical servo system of high electric generator performance is used mostly type permanent magnet synchronous ac servo motor, control drive more rapid and accurate positioning of the digital position servo system. Manufacturers such as Germany's Siemens, typical American Morgan cole and Japan panasonic, yaskawa company, etc.

1, each computer is about 200 ~ 200 w power consumption (about 1 ~ 1.5 A), then 10 computers need A 2.5 mm square copper www.dongfeng- motor.com wire power supply, or may generator diesel generator price be A fire. 2, 3 big horse air-conditioning consumes about 3000 w (about 14 a), then 1 air conditioner need to separate a 2.5 mm2 copper wire of ac synchronous generator power supply. 3, now of the housing into line is commonly 4 square millimeter of copper wire, auto spare parts therefore, at auto spare parts the same time open the electrical appliances (5500 w) shall not exceed 25 a, someone to the wire in the house changed into 6 mm square copper wire is not useful, because enter the wire is 4 acmotor2.blogspot.com mm square meters. 4, early housing (15 years) into the line is generally 2.5 square mm aluminium wire, therefore, at the same time open the electrical appliances shall generator set not exceed 13 a (2800 watts). 5, power consumption is relatively large home appliances: air conditioning 5 a (1.2), electric water heater 10. water pump price A, 4 a, microwave cooker 4 a, 8 a dishwasher, washing machine with drying function 10. A, electric water boiler 4 a. In power caused by the fire, 90% is caused by joint fever, so all the joints shall be welded, cannot contact welding device 5 ~ 10 years (such as sockets, air switch, etc.) must be replaced.

Asynchronous motor produce abnormal vibration and abnormal sound mainly has two aspects of mechanical and electromagnetic. Mechanical reasons: (1), motor blades damage or tighten screw loose blades, blades and the blades into cover, clattering sound produced by it with the weight of the sound, the big small; (2), due to the improper bearing wear or shaft, motor rotor eccentricity caused serious when will make, rotor rub, make the motor produces severe vibration and electric fan motor uneven scratches. (3), motor due to long-term use of the anchor bolt is loose or not foundation, thus the electromagnetic torque of the motor under the action of abnormal vibration; (4), long-term use of the electric motor 12v 500w motor due to a lack of lubricating oil in the bearing inner formed in mill run or bearing steel ball is damaged, therefore make the hiss of the motor bearing interior an exception or purr. Electromagnetic reasons: (1), the normal operation of the motor suddenly appear abnormal sound, in the load running speed decreases significantly, while a low along the roar, may be unbalanced three phase current, the heavy load or single phase operation; (2), the normal operation of the motor, if the stator and rotor winding short-circuit fault ac induction motor 110kw or squirrel cage rotor broken bar when electric are high when low buzz.

The fuselage vibration. (1), due to long-term lack of oil running of motor bearing, friction losses increase bearing overheating. In addition, when the motor running, the oil too much or too thick will also cause bearing overheating; (2), when the replacement of lubrication, due to the lubricating oil mixed with hard grain impurity or bearing cleaning uneven net, make bearing wear and overheating, even may damage the bearing; (3), due to improper assembly, fixed end cover wholesalemotor.blogspot.com screw tightness is differ, in a straight line between the two bearing center is unbalanced or bearing outer ring. The bearing rotation is not flexible, adds load after growing friction and heat; (4), belt too tight or motor and were not in a straight line with mechanical shaft center, and thus can increase the bearing load and heat; (5), bearing improper selection or poor quality, such as bearing internal and external ring rust, individual steel ball is not round, etc.; 6, in the operation of the motor bearing damaged, resulting in bearing overheating.
