DKJ electric actuator product configuration Description

Common DKJ electric actuator product configuration: position locator - position locator from the pre-filter, signal detection, comparative amplification, isolated output, power output and other components, and its role is to amplify the weak signal to the power output, final control actuator output position. If the system uses a simple contact control or manual operation only you can not use the position locator. DKJ electric actuator - the actuator by a servo motor, reducer, position transmitter consists of three parts, are described below: ???????? A: DKJ electric actuator servo motors: squirrel cage type two? phase servo motors, evenly distributed on the stator electrical angle of 90 degrees two stator windings, respectively control the electric actuator forward and reverse phase capacitance by the two-phase excitation winding each other and control phase, its synthetically produced rotating magnetic field of the stator, the stator rotating magnetic field generated in the rotor squirrel cage rotor current, rotor current and the interaction of the rotating magnetic field, generating an electromagnetic torque on the rotor. Direction of rotation is determined by the phase voltages on both windings, this series servo motors are specially designed for the executive body, starting torque, the mechanical properties of soft. ?? B: DKJ electric actuator reducer: The involute flat teeth and small teeth difference combination drive transmission, which is characterized by small size, transmission ratio, high efficiency, long life, etc., all equipped with electric actuators handwheel for next use adjustment and accident conditions. ???????? C:? DKJ electric actuator position transmitter: the part of the electric actuator position limit detection and indication and electrical components, the use of conductive plastic potentiometer as a position sensor, the useful life up to 50 million times, linear precision of up to 0.2%, the position of the transmitter section uses a modular structure, the overall resin sealed limit switches with waterproof switch in order to improve the protective performance, 0-10mA and 4-20mA products Universal. ??????? D: DKJ electric actuator electric operator DFD series consists of switch and recessed milliammeters, whose role at the time of commissioning or fault on the electric actuator for manual operation, while mA Table indicates the host system machine signal and the actuator position signal. ?
