ZFeng 900 Series 11Kw-T-G General Vector Variable Frequency Drive
Vector frequency drive is based on vector control technology, which transforms the three-phase system into an M-T two-phase system through coordinate transformation. It decomposes the stator current vector of the AC motor into two DC components (magnetic flux component and torque component), thereby achieving separate control of the magnetic flux and torque of the AC motor. This control method enables AC motors to have control characteristics similar to DC motors, greatly improving the control performance of AC motors.
Functional advantages
energy efficiency Soft start/soft stop: reduces mechanical impact, lowers wire rope and brake losses, and extends equipment lifespan. Optimize energy efficiency: By limiting current and reducing frequency, it can save 20% -50% energy compared to traditional control.
intelligent control Modbus communication: Integrated remote monitoring system to achieve device networking and real-time data transmission. Anti sway function: reduces load sway through torque control, improving the safety of high-altitude operations.
Multi motor collaboration Synchronous control: When multiple motors cooperate in a large crane, ensure that the output torque is consistent with the speed to avoid unbalanced load.
Selection suggestions
Load type: Vector control is selected for constant torque loads (such as lifting mechanisms), and V/F control is selected for variable torque loads (such as ventilation equipment).
Power matching: Select the frequency converter capacity based on the rated current of the motor, taking into account 1.33 times the overload factor.
Braking method: In frequent braking scenarios (such as lifting mechanisms), it is recommended to choose a feedback braking unit.
