Follow on Google News | Closed loop vector control and torque control frequency inverterSuperb closed loop vector control (field-oriented control) frequency inverter, optimized software and hardware design
Available voltage range: 380 VAC - 480 VAC (323 VAC - 528 VAC): 380 V, 400 V, 415 V, 440 V, 460 V, 480 V Vector Control 1: (enhanced V/F control mode) Offering excellent vector control performance and insensitive to motor parameters. Startup torque: 0.50Hz 180% rated torque (high torque at low frequency) Speed adjustment range: 1:100 Speed stabilization precision: +- 0.5% 0.50Hz controllable motor stable operation with 150% rated torque. Vector Control 2 (Without Encoder Speed Feedback): Precise speed sensorless vector control technology realizes AC motor decoupling, enabling the DC motorization of operation control. Startup torque: 0.25Hz 180% rated torque (large torque at low frequency) Speed adjustment range: 1:200 Speed stabilization precision: +- 0.2% 0.25Hz controllable motor stable operation with 150% rated torque. Vector Control 2 (With Encoder Speed Feedback, closed loop vector control mode): Startup torque: 0.00Hz 180% rated torque (large torque at low frequency) Speed adjustment range: 1:1000 Speed stabilization precision: +- 0.02% Open Loop Torque Control Mode: Independent current loop control to realize true torque control, supporting online switching of torque control and speed control. Torque precision: +-5% Torque response time: <20ms Closed Loop Torque Control Mode: Independent current loop control to realize true torque control, supporting online switching of torque control and speed control. Torque precision: +-5% Torque response time: <10ms Applications: agricultural water distribution, agricultural water intake, agricultural water treatment, food and beverage, biofuel, commercial buildings, HVAC, machine tools (lathe, rotary cutting machine, linear cutting machine, spindle control (http://www.ecodrivecn.com/ End
