Ano ang Katumbas na Sirkwito para sa Induksyon Motor?

Pangangailangan ng Katumbas na Sirkwito

Ang katumbas na sirkwito ng induksyon motor ay nagpapakita ng mga panloob na parametro nito tulad ng pagkawala gamit ang mga inductor at resistor. Ang induksyon motor laging tumatakbo sa ibaba ng synchronous o punong load speed at ang relatibong pagkakaiba-iba sa pagitan ng synchronous speed at bilis ng pag-ikot ay kilala bilang slip na ipinahayag ng s.

 Kung saan, Ns ang synchronous speed ng pag-ikot na ibinigay ng-Kung saan, f ang frequency ng supply voltage.P ang bilang ng poles ng makina.

 Mga Komponente ng Katumbas na Sirkwito

Kabilang dito ang mga elemento tulad ng winding resistance (R1, R2), inductance (X1, X2), core loss (Rc), at magnetizing reactance (XM).

Tumpak na Katumbas na Sirkwito

Nagbibigay ng detalyadong mga parameter, nagpapakita ng power at pagkawala sa motor.

Dito, R1 ang winding resistance ng stator.

X1 ang inductance ng stator winding.

Rc ang core loss component.

XM ang magnetizing reactance ng winding.

R2/s ang power ng rotor, kung saan kasama ang output mechanical power at copper loss ng rotor.

Aproksimasyon ng Katumbas na Sirkwito

Nagsisimplipika ng pagsusuri sa pamamagitan ng paglipat ng shunt branch ngunit mas kaunti ang katumpakan para sa mas maliit na motors.

Single-Phase Induction Motor

Gumagamit ng double revolving field theory upang ipaliwanag ang katumbas na sirkwito nito, na kinakatawan ang forward at backward rotating fields.

Rectifier vs Power Transformer: Key Differences
Differences Between Rectifier Transformers and Power TransformersRectifier transformers and power transformers both belong to the transformer family, but they differ fundamentally in application and functional characteristics. The transformers commonly seen on utility poles are typically power transformers, while those supplying electrolytic cells or electroplating equipment in factories are usually rectifier transformers. Understanding their differences requires examining three aspects: working

SST High-Frequency Isolated Transformer Core Design and Calculation Material Characteristics Impact:Core material exhibits varying loss behavior under different temperatures, frequencies, and flux densities. These characteristics form the foundation of overall core loss and require precise understanding of nonlinear properties. Stray Magnetic Field Interference:High-frequency stray magnetic fields around windings can induce additional core losses. If not properly managed, these parasitic losses
