The F-series electric actuator adopts the traditional AC motor, and the speed and torque cannot be changed; it is a highly cost-effective AC intelligent product.
2. The F-Series actuator product structure
Mechanical part
(1) Gear transmission mechanism: adopts the very mature planetary gear transmission principle which has been used for more than 40 years.
(2) Features: compact structure, high efficiency, multi-point average force, strong bearing capacity; its transmission efficiency, service life is much higher than worm worm and positive gear transmission; stable operation, strong impact resistance and vibration ability.
(3) Hand wheel mechanism: using the variable planetary gear structure, can be directly manually operated without clutch switch, remove the troublesome clutch device, even if it is running, can also turn the hand wheel, will not cause damage to the actuator.
(4) Double limit: mechanical + electronic double limit.
(5) intelligent control unit: F series control unit mainly adopts the German advanced mature control concept and technology, with the increasing level of science and technology and electronic components increasingly integrated, modular, sophisticated, D + R researchers of the original control circuit streamline, integration and optimization, and adopt 8 CPU digital control technology, gave birth to the more powerful, control performance more stable, higher control accuracy, lower cost of F-AS intelligent controller.
F-AS intelligent controller: it is a cost-effective, economical, integrated digital controller. The super-large scale integrated circuit is adopted to ensure the realization of all basic control functions except for frequency conversion and speed control, while also ensuring the compact structure and delicate appearance. It also has a perfect self-diagnosis and protection function.
(6) Motor: D + R specially designed motor has the characteristics of large starting torque, small starting current, small temperature rise, and has class F insulation and temperature protection, especially suitable for valve execution device. In addition, its rotating inertia is particularly small, which is conducive to the braking and braking of the motor, which can ensure accurate positioning and prevent overshooting phenomenon. The F-series electric actuator mainly adopts AC Asynchronous motor (90,400,750,1200,2000W; speed 2800rpm).
