Specifications
KE300A Series High Performance Open Loop Vector Control Inverter widely used for the asynchronous
motor driving where better speed control and low-frequency torque are required . KE300A is built on TI's powerful DSP-based motor control chip, with the adoption of the sensorless current vector
control (SVC) and open-loop torque control
(TC). KE300A enhances its reliability to meet the requirements of environment adaptability, customized and industrialized design with more optimized functions, more flexible applications and more
stable performance.
