Dynamo of pottery and porcelain is prime mover procrastinates move dynamo rotor to overcome " electric field gravitation " and generation electric current.
Contrast above all two kinds of dynamo place need procrastinate use power. Well-known, the output power of the dynamo can produce a counterforce to the rotor of the dynamo, output power is needed to urge power greatly more bigger also, mix traditionally no matter of pottery and porcelain same. The influence drives the physical index of power, have the following 4: P of power of ① rated output is rated; Revolution of ② per sec. , namely frequency F: ③ rotor has R of effectiveness quadrature radius to turn: ④ brings the KW of obstruction Kg ／ that field of force causes. To the 4th, dynamo of porcelain of opposite Yu Tao is to overcome " electric field gravitation " and acting. Traditional dynamo is to overcome " magnetic field gravitation " and acting. Classics imitate experiment measures: Every KW electric power produces magnetic field gravitation to be 1750kg, every KW electric power produces electric field gravitation to be 500kg.
Go to the lavatory for clear contrast, our regulation is both: Power of ① rated output is same, magnetic field of =P of P phone specified number; ② frequency is same, =f of magnetism of F report =f; ③ the rotor of coequal power level has two kinds of dynamoes effectiveness quadrature radius is equal, r report turns =r magnetism turns; ④ cites imitate experiment value; Force of attrition of ⑤ mechanical loss is ignorred. Criterion of two kinds of dynamoes procrastinate use power, give out next type: Does P report push =p phone specified number? F? Does R turn? 500kg ／ KWDoes P magnetism push =p magnetism specified number? F? Does R turn? 1750kg ／ KWP report is pushed, does P magnetism push =(p phone specified number? F? Does R turn? 500kg ／ KW) , (P magnetism forehead? F? Does R turn? ／ of 1750kg ／ KW)=1 3.5
Fall in the situation with output same power namely, 3 of traditional dynamo, 5 times.
If say the efficiency of dynamo of electromagnetism induction type makes an appointment with 40 ％ , criterion the efficiency of dynamo of pottery and porcelain is 140 ％ , conversation law of blow energy of dynamo of pottery and porcelain.
