KTN-R-250

KTN-R-250 is a three-phase voltage thyristor bridge reducer used for regulator or speed control of asynchronous motor. Its main application field includes the industries like chemical engineering, metallurgy, pump and fan, textile, mining and transportation. Because of various application fields, it is a extremely common motor control device for most of the end users.The working principle of KTN-R-250 reducer is quite simple, which mainly controls the on and off of the thyristor bridge. In addition, it provides a simple set of parameters to adjust the output characteristics of the driving motor. Its control modes include current mode, torque mode, speed/frequency mode and vector control mode.In the current mode control, the KTN-R-250 reducer controls the on and off of the thyristor bridge with current feedback from the motor, which can effectively improve the acceleration and dynamic performance of the motor, and reduce the impact of motor thermal inertia on the speed.In torque mode control, the KTN-R-250 reducer sets the value of the torque applied to the motor, and controls the on and off of the thyristor bridge to ensure that the torque output is in line with the set value. This mode can make the motor torque load stable, and accurately track the set values of acceleration and deceleration.In speed/frequency mode, the KTN-R-250 reducer sets the speed or frequency of the motor, and controls the on and off of the thyristor bridge to ensure that the speed is up to the set value. This mode can effectively improve the tracking performance of the motor speed.In the vector control mode, the KTN-R-250 scooter uses the current feedback from the motor to obtain the information of the rotation speed and position of the motor, and then controls the on and off of the thyristor bridge according to the vector control algorithm. This mode can make the speed and torque of the motor stable, and can adapt to the load changes accurately and quickly.The KTN-R-250 reducer is suitable for various motor control applications due to its excellent performance, high reliability and good cost performance. It can operate stably in harsh environments and meet the requirements of customers for various motor control applications.
