English Introduction： The DXK-4D electromagnetic speed-regulating motor controller is a control device for electromagnetic slip speed-regulating motors, capable of achieving smooth and precise control of speed-regulating motors. It employs advanced technologies such as single-phase half-wave controlled rectifier circuits, integrated pulse triggers, speed regulators with PID characteristics, and tachometer negative feedback circuits, effectively enhancing the stability and reliability of motor operation. The controller s power supply is AC220V±10%, 50Hz, with a maximum output rating of DC85V, 8A. It can control speed-regulating motors with a power range of 45-90KW, meeting the speed-regulating requirements of high-power motors in various industrial scenarios. The tachometer generator has a voltage-speed ratio of ≥2V/10rpm, with a speed variation rate of ≤1.5%, speed regulation accuracy of ≤0.5%, and a speed regulation range of 100-1370rpm (the maximum speed refers to the motor nameplate). The control signals include 0~10V, 1~5V (output impedance 20K), 0~10mA (input impedance 1K), and 4~20mA (input impedance 250Ω). The speed signal output is 4~20mA (load impedance ≤650Ω) or 0~10mA (as required at the time of order or adjusted by the user), and the low-speed limit range is 0~600rpm. This controller is widely used in various industrial motor speed-regulating applications, such as speed regulation of conveyors, fans, pumps, and other equipment, enabling stepless speed regulation of motors to improve production efficiency and the flexibility of equipment operation.
