Textile Machine Vector Frequency Inverter 3AC 1.5KW 380V ~ 460V
High-performance current vector technology, using special control
algorithms, not only meets the special requirements of the air jet
loom for acceleration time, but also has the advantages of
convenient speed regulation, stable operation and high reliability.
The traditional replacement belt shifting mode is completely
abandoned, so that the speed control can be steplessly regulated,
the control is more precise, and the adjustment is more convenient.
The efficiency of the air jet loom is greatly improved, and the
damage of the mechanical replacement belt to the equipment is
solved.
