Face up to the application of single-phase transformer in our country, single-phase transformer and single-phase power supply technology has been developing, as early as the late 1950 s to the single-phase transformer have exported abroad. Over the years, the development of science and technology to promote the Three phase motor development of the single-phase transformer, roll core, amorphous iron core technology application in the single-phase transformer, can greatly reduce the loss in the transformer core. According to the analysis, after the urban and rural power grid renovation to a certain degree, the network loss share will greatly reduce the line loss, no-load loss of distribution transformer will make up the main status of the network loss. Only greatly reduce the loss of iron core, is expected electric fan motor parts to reduce the loss of grid power. Therefore, the roll core, amorphous iron core single-phase transformer has great development potential. At present, the three-phase transformer and three-phase centralized power supply system is still dominant, single-phase transformer and single-phase power supply generator set system is its supplement. Practical application in transformer, we should make full use of three-phase transformer single-phase transformer and their respective advantages and characteristics, according to load condition to choose suitable varieties of transformer, power supply radius with power in economy

Common fault analysis and maintenance - running motor fault analysis

Has swept chamber, vibration, mechanical bearing overheating and damage failure. Asynchronous motor, air gap between rotor is small, easy to cause, collision between the rotor. General because indoor end cover shaft hole wear or stop end cover mouth and base check mouth wear deformation, make the stand, end cover, single phase ac motor rotor misalignment caused chamber. Vibration should be distinguish is caused by the motor itself, or poor transmission device, or a mechanical load transfer, and then ruled out according to specific conditions. Belong to cause the vibration of the motor itself, mostly due to the rotor dynamic balance is not good, bad and bearing, shaft bending, or end cover, frame, rotor misalignment, or motor installation of foundation, installation does not reach the designated position, loose fasteners. Vibration can produce noise, will also generate additional load. Motor after electrify found speed to slow, analyze its reasons in many aspects, capacitor start motor capacity lack serious leakage, whether the capacitor voltage is too low, or a squirrel cage rotor article aluminum parts have a serious accident shrinkage cavity, breaks, and so three phase asynchronous motor on and so forth, especially the washing machine motor starting and positive and negative work alternately, often make article turned aluminum induced current big and make electromagnetic electricalmotor1.blogspot.com force increases, all can produce turned aluminum strip break, resulting in slow running to, serious when make the rotor fever and edm and burn winding lines).

It refers to the shell design and manufacture according to the prescribed conditions, can prevent the dust ac electric motor into the motor shell or cannot completely prevent dust to enter, but it into the quantity does not interfere with the safe operation of the motor, and internal dust accumulation is not easy to produce fire danger, when using, also won't cause around with explosive dust mixture explosion of the motor. Its features are: (1) the shell has high sealing, in order to reduce or prevent dust acmotor2.blogspot.com into the enclosure, even to enter, it into the quantity also not form fire danger. (2) control the shell top surface allow temperature does not exceed the prescribed temperature group. At electric generator present, has been used in national food reserve of mechanized equipment. The national standard of dust explosion-proof electrical equipment for GBl2476.1-90 dust explosive environment with explosion-proof electrical equipment.

Stepper motor and ac servo motor performance comparison of different control pre

Two-phase hybrid stepper motor step Angle is 3.6 ° and 1.8 °, 5 phase hybrid stepping motors interval Angle is 0.72 ° and 0.36 ° in general. electric motor single phase motor There are also some high-performance stepper motor step Angle is smaller. Such as cross company produces a kind of stepping motor for wire walking machine, where the step Angle is 0.09 °. BERGER LAHR company in Germany (BERGER LAHR) production of three-phase hybrid water pump price stepping motor where the step Angle can dial the code permanent magnet generator switch is set to 1.8 ° and 0.9 ° and 0.72 ° and 0.36 ° and spare parts 0.18 ° and 0.09 acmotor2.blogspot.com ° and 0.072 ° and 0.036 °, combine www.dongfeng-motor.com the two and five phase hybrid stepper motor step Angle. Control precision of the ac single phase motor servo motor by the motor shaft after the rotary encoder. Panasonic digital ac servo motor, for example, in line with standard 2500 encoder of the motor, drive due to the permanent magnet generator internal used four frequency multiplication technology, the pulse equivalent to 360 ° / 10000 = 0.036 °. For with 17 encoder of the motor, drive each receive 217 electric generator = 131072 pulse motor turns a circle, namely the pulse equivalent to diesel generator set 360 ° / 131072 = 9.89 seconds. Interval Angle is 1.8 ° is 1/655 of the pulse equivalent of stepper motor.
