How does the closed-loop vector control technology used by DM Motor For Water Jet Looms ensure low-speed fluctuations of the spindle?

Working principle of closed-loop vector control technology
The closed-loop vector control technology is based on real-time control of motor speed and torque, by decomposing the motor's current vector into two components: one is consistent with the direction of the magnetic field to control the magnetic flux; the other is consistent with the rotor speed to control the electromagnetic torque.

In the application of DM Motor For Water Jet Looms, the core advantage of closed-loop vector control technology lies in its real-time adjustment ability of the spindle. This technology uses high-precision sensors and control algorithms to monitor the operating status of the motor in real time, including speed, torque and load conditions.

Challenges of low-speed fluctuations of the spindle
In actual operation, water jet looms often require frequent start-stop and speed adjustment, which places high demands on the performance of the motor. Especially when running at low speeds, traditional motors are prone to fluctuations in the spindle due to inaccurate speed control, which in turn affects the uniformity and quality of the fabric.

DM Motor For Water Jet Looms effectively solves this problem through closed-loop vector control technology. It can maintain extremely high speed stability under low-speed conditions, ensuring minimal spindle fluctuations, thereby improving the overall performance of the loom.

How to achieve low-speed and efficient control
The closed-loop vector control technology of DM Motor For Water Jet Looms ensures efficient control at low speeds through a precise feedback loop. In actual operation, when the spindle speed decreases, the system monitors the torque changes of the motor in real time and maintains the stability of the motor output through dynamic adjustment of the current.

In addition, DM Motor also uses an advanced current prediction algorithm to adjust the current in advance by predicting future load conditions to avoid the impact of sudden load changes on motor performance.

Combination of energy efficiency and closed-loop control
DM Motor For Water Jet Looms not only performs well in low-speed fluctuation control, but also improves the overall energy efficiency of the system through closed-loop vector control technology. The closed-loop control system avoids the energy waste of traditional motors in the inefficient range by adjusting the current output in real time.

DM Motor's energy efficiency performance not only meets the international IE5 standard, but also saves users 20% to 30% of energy consumption each year, equivalent to 5000 kWh of electricity savings.

Advantages in practical applications
DM Motor For Water Jet Looms' closed-loop vector control technology has shown many advantages in practical applications. First, this technology enables the loom to maintain efficient and stable operation under various working conditions, especially when weaving high-quality fabrics, the low-speed stability of its main shaft is particularly important. Second, the closed-loop control system greatly reduces the wear on mechanical parts, extends the service life of the equipment, and reduces maintenance costs.
