Motor wiring mantra: www.dongfeng-motor.com "1.5 plus two, plus three" 1.5 "after the four plus four, six plus six," "increasing after 25 plus five, after 50 minus five" 102 conductor, the best number "the mantra diesel engine is equipped with wire directly based on the three-phase 380 v ac motor capacity." 1.5 plus two "said 1.5 was copper, plastic wire, can go with 3.5 kW and the following motor. Because of the 4 kW motor selection of close to 3.5 kW use scope, and the formula has certain allowance, so the quick table 4 kW motor under the selected conductor take 1.5 was." After 2.5 plus three ", auto spare parts "four plus four", said was 3 phase induction motor 2.5 and 4 was the copper plastic wire to auto spare parts respectively 5.5 kW, 8 kW motor." After six plus six, "said from the beginning of the 6 was, with the" increase 6 kW motor. "that squirrel cage induction motor was can match 12 kW, choose similar specification with 11 kW motor.

10 was 16 kW, choose similar specification with 15 kW motor. 16 was 22 kW acmotor2.blogspot.com motor can match. The middle and 18.5 kW motor, also copper plastic line 16 was chosen." After 25 plus five ", it is said from 25 was addend from six to five. 25 was 30 kw electric motor can match. 35 was 40 kw can match, choose similar diesel generator set specification with 37 kw motor." Increasing after 50 minus five ", it is said that since 50 was made up into a reduced, and it is increasing step by step to lose five. 50 was 45 kw motor can be produced (50-5). 70 was can match up to 60 kw (70-10), select similar specification is equipped with 55 kw electric motor. 95 was can match 80 kw (95-15), choose similar specification with 75 kw motor." 102 conductor, with the number ", magnetic generator it is said that 120 was the copper plastic wire can match 100 kw motor, phase selection specifications namely 90 kw electric motor.

Frequency conversion air conditioner according to the compressor room is using ac or dc motor and is divided into two kinds of ac frequency conversion mode and dc frequency conversion way. 1, communication. 50/60 hz ac?? Direct current (dc)?? Alternating current (120 hz) 30??? Ac compressor. 2, dc way. 50/60 hz ac?? Direct current (dc)?? Dc compressor. Compare these two approaches, more advanced dc mode, displays in more save electricity, run more peaceful and more strong heating effect, etc. And, of course, the price of a dc frequency converting single phase induction motor air conditioner was higher. More than 95% at present, the Japanese room air conditioner are frequency conversion air conditioning, and the direct current frequency conversion air conditioning and dominant.

Midea air-conditioning division since the early ninety s began work on human resources development of frequency conversion air conditioning, and insist for a long time and Toshiba, panasonic until companies for technical cooperation. With the improvement of the actual purchasing power of Chinese consumers, our company will to dc frequency conversion air conditioning market in a timely manner. Beauty of the dc frequency conversion air conditioning, not only the Three phase motor compressor is dc compressor (including 35 gw (KFR? / BP2Y is the use of high performance double rotor compressor), and indoor and outdoor air blower motor is a brushless dc motor, using the world's most advanced digital frequency conversion control technology, run more smoothly, lower noise, higher efficiency (more than magnet generator 10% higher than that of ac frequency conversion air conditioner).

The application of squirrel-cage asynchronous motor soft starter - working principle of the soft starter

Soft starter is a collection of soft start,soft stop,light load energy saving motor parts and multi-functional protection of motor control device.It not only realize no impact in the whole process of starting and smooth starting current,and according to the characteristics of the motor load to adjust the parameters in the process of starting,such as current limiting value,starting time,etc.In addition,it also has the protection of motor function,that is fundamentally solves the disadvantages of traditional step-down starting equipment.Soft starter used three opposite parallel thyristor as a voltage regulator,to wear it while plugged motor run capacitor into a power supply and the motor stator.

This circuit such as three-phase fully-controlled bridge rectifier circuit,main circuit diagram as shown in figure 1.When using the soft starter motor,the output of the thyristor voltage increase gradually,motor speed gradually,until the thyristor conduction,all motor electricalmotor1.blogspot.com working in the rated voltage on the mechanical properties of smooth start,reduce the starting current,avoid start over-current trip.For motor to achieve rated speed,the end of the boot process,the soft starter automatic bypass contactor to replace has completed the task of thyristor,provide the rated voltage for the motor magnet motor operation,to reduce the heat loss of thyristor,prolong the service life of the soft starter,improve the work efficiency,and make the power grid to avoid the harmonic pollution.Soft starter and also provide function of soft parking,soft parking,in contrast to the soft start process,voltage decreases gradually,speed gradually decreases to zero,to avoid the free parking torque caused by the impact.

The dc grounding method 3

Hybrid grounding: so-called hybrid grounding is within a device of the circuit board in the shortest wire connected to the chassis,or signal circuit is the base of the related equipment,in the shortest wire grounding connected to the same metal body,and then multiple devices with wire received a fixed in the same spot.Like this grounding method called hybrid grounding.Hybrid grounding in engineering is the most simple way,is in the ac power into house master switch,the zero line repeat grounding (or zero line connects to housing on the structure of the main generator stator steel bar),and then in the power of the zero line leads to a PE line should wholesalemotor.blogspot.com connect all grounding point.Second,ring grounding network for earth,is the grounding body into a closed loop around the building.

Within such ground network to make the interface of the electric field electric motors price distribution is evener,step to reduce the harm to people,and also reduce indoor when affected by lightning,and because of the large ground potential gradient to counter the risk of high pressure equipment.Three,base earthing body: use the steel bar inside the building foundation,according to the requirements of "specification" connection low rpm generator alternator of grounding body called base earthing body.Some people think that,in the basis of reinforcing bar,concrete cover the impossible and the conduction of grounding body.Is,in fact,good insulation dry concrete and concrete in contact with the water of the soil containing water,capillary absorbs moisture to keep the concrete with high water content in concrete,and thus reduce the resistivity of the concrete with the earth if one.
