What Does the S2 Duty Cycle Mean in Actuators (Electric Valves)?

Many people have questions about the S2 duty cycle in actuators or electric valves. What does it mean, and why is it defined this way? 1. The Origin of S1, S2, S3, and S6 Duty Cycles The S1, S2, S3, and S6 duty cycles originate from electric motor classifications, with a primary focus on thermal balance. The goal is to ensure that the motor does not overheat due to continuous operation. Definitions of Common Motor Duty Cycles: S1 (Continuous Duty Cycle): Operates at a constant load for a long enough period to reach thermal equilibrium. S2 (Short-Time Duty Cycle): Operates under a constant load for a set time, but not […]

電圧出力信号はなぜ特定の条件で発振するのか？

  1. Voltage Signal Transmission Path As shown in Figure 1, a voltage signal transmission system consists of three key components: Negative feedback voltage output circuit Signal transmission cable Includes parasitic capacitance (C1) and parasitic inductance (L1), which depend on cable length and wiring layout. Input signal acquisition circuit May include a low-pass filter (L2, C2). 2. Why Does Oscillation Occur? In a negative feedback voltage signal system, the input signal is calculated as: ∣Xi′∣=∣Xi∣−∣Xf∣|X_i’| = |X_i| – |X_f| However, if the feedback signal (|Xf|) is phase-shifted by 180°, the equation changes to: ∣Xi′∣=∣Xi∣+∣Xf∣|X_i’| = |X_i| + |X_f| This means that even if no input signal is applied (|Xi| = […]
