Ukusekelwa Kwezobuchwepheshe

Ungathola ulwazi ngokusebenzisa amatemu amamotho, angakusiza ukhethe umkhiqizo ofanele.

TERMINOLOGY YEMOTO

Isilinganiso
Isilinganiso siwukucaciswa komkhawulo wokusebenza kwemoto, okuhlanganisa amandla okukhipha imoto, i-voltage, i-current, i-frequency, i-torque ne-rpm, njll. Mayelana nokukhuphuka kwezinga lokushisa, kunezinhlobo ezimbili, ukulinganisa okuqhubekayo kanye nesilinganiso sesikhathi esifushane.
I-synchronous RPM
Imvamisa yezimoto nezigxobo zinganquma i-motor rpm.Ifomula yesithenjwa ingokulandelayo:
Ns = ( 120 xf ) / P
I-Ns:I-rpm yokuvumelanisa (rpm)
120:Njalo
f:Imvamisa
P: Izigxobo
I-Torque elinganiselwe
I-torque ku-rpm elinganiselwe yi-torque elinganiselwe.
AKUKHO MLAYIZO RPM
I-Motor rpm ngaphandle komthwalo.

Isilinganiso Esiqhubekayo kanye Nesilinganiso Sesikhathi Esifushane
Ukulinganisa okuqhubekayo kubhekisela ekusebenzeni okuqhubekayo kwenjini ngaphansi kokukhipha okulinganiselwe;isilinganiso sesikhathi esifushane sisho injini egijima ekuphumeni okulinganiselwe phakathi nenkathi ethile yesikhathi.
Amandla Okukhiphayo
Ikhonjiswe amandla angenziwa injini phakathi nesikhathi seyunithi.Amandla enziwa injini anqunywa i-rpm ne-torque.Ifomula yesithenjwa ilandelayo:
Okukhiphayo (Kw) = ( T x N ) / 97400
T:Torque (Kg.cm)
N: RPM
I-1HP: 0.746kw
Iqala i-Torque
I-torque ikhiqizwa ngokushesha lapho injini iqalwa.I-motor ngeke iqale uma umthwalo umkhulu kunetorque enjalo.
Slip
Enye yezindlela zokukhombisa i-rpm, ifomula yereferensi njengoba ingezansi:
S = ( Ns - N ) / Ns
S: Slip
Ns:I-rpm ehambisanayo
N: RPM ngaphansi kwanoma yimuphi umthwalo

UKUKHETHWA KWEMOTO

01
Ukwethulwa Okujwayelekile Kochungechunge Lwe-Speed ​​Reducer Ukubalwa Kwesilinganiso Segiya Yokuncishiswa
Amakhasimende akhetha isilinganiso esifanele kakhulu segiya lokunciphisa ngokwesidingo sawo sokufanisa ukuphuma kwe-rpm yesinciphisi segiya ne-rpm yemishini esebenzayo.(AAC)
i = Nm / Ng noma 1 / i = Ng / Nm
i:Isilinganiso segiya
Ng: Isivinini sokuphuma kwesinciphisi segiya (rpm)
I-Nm: Isivinini sokugijima kweMoto (rpm)

02
I-Torque Calculation Formula ye-Direct Link Speed ​​Reducer
Ikhasimende likhetha imodeli efaneleke kakhulu ukuze ivumelane ne-torque yomshini yesinciphisi isivinini.(Itorque eqhubekayo)
Tg = Tm xix η
Tg: I-torque yokukhipha isinciphisi
Tm: I-torque ye-motor
i:Isilinganiso
η:Ukuphumelela kokunciphisa isivinini
