DC motor

Electric actuator is a new type of electric linear actuator, which is mainly composed of drive motor, reduction gear, screw, nut, guide tube, guide sleeve, actuator, mounting base, spring, shell and worm gear, micro-control switch, etc. It can realize long-distance control and centralized control. Electric push rod in a certain range of travel for back and forth movement, general electric actuator standard stroke 50, 100, 150, 200, 250, 300, 350, 400mm, special stroke can be customized according to the requirements of different application conditions. According to different application loads and design of different thrust electric actuator, generally its maximum thrust up to 6000N, no load speed 3mm ~ 45mm / s. Electric actuator with 12V/24V DC motor as a power source, there are supporting power controller, the controller's input voltage is generally 110V/220V, the output voltage of 12V/24V, powered actuator operation. Where there is power can be used, very convenient. The use of electric actuator as an actuator can not only reduce the use of pneumatic actuators required by the gas source device and auxiliary equipment, but also reduce the weight of the actuator. Electric actuators and hydraulic cylinders compared to no hydraulic source, do not need a complex set of system support, including pumps, piping, valves, filters, many joints, and so on. Therefore, from the point of view of energy saving, electric actuator actuators than pneumatic-hydraulic actuators have obvious energy-saving advantages. Electric actuator with reliable performance, sensitive action, smooth operation, push and pull the same, good environmental adaptability, etc. With the development of science and technology in modern society and the improvement of people's living standards.  

The power of the micro reduction motor should be selected based on the required power of the product, and the micro motor should be operated at rated load as much as possible. When selecting, the following two points should be noted:1.If the power of the micro motor is selected too low, it will cause long-term overload of the micro motor, causing insulation damage due to heating, and even the micro motor to be burned;2.If the power of a micro DC motor is selected too high, its output mechanical power cannot be fully utilized, and the power factor and efficiency are not high, resulting in waste of electrical energyWhen selecting a micro reduction motor for different products, it is necessary to correctly select the power of the micro motor through the following calculations or comparisons:For constant load continuous operation mode, if the power Pl (kw) of the load is known, the required power P (kw) of the micro motor can be calculated as follows:P=Pl/nln2, whereNl is the efficiency of the product;N2 is the efficiency of the micro motor (i.e. transmission efficiency).The power calculated according to the above equation may not necessarily be the same as the product power. Therefore, the rated power of the selected micro motor should be equal to or slightly lower thanGreater than the calculated power.Compared with continuous rated micro motors with the same power, short time rated micro motors should be selected as much as possible when conditions permit. For micro DC reduction motors with intermittent working quotas, the power selection should be based on the size of the load duration, and micro motors specifically designed for intermittent operation should be selected.
