Today's
electric drying racks are usually driven by linear motors, while the previous electric
drying racks used ordinary rotating electric machines. Why? Where is the linear motor driven transmission? let's see it together.
(1) The linear motor-driven transmission does not require any conversion device to directly generate thrust. Therefore, it can eliminate the intermediate conversion mechanism, simplify the entire device or system, ensure operational reliability, improve transmission efficiency, and reduce manufacturing. Cost and easy to maintain. According to foreign data reports, there was a washing machine with a linear motor that worked continuously for 24 hours every day for 24 hours without any maintenance.
(2) The ordinary rotating electric machine is limited by the centrifugal force, and its peripheral speed is limited. When the linear motor is running, its components and transmissions are not subjected to centrifugal force like the rotating electric machine, so its linear speed can be avoided. limit.
(3) The linear motor directly generates linear electromagnetic thrust through electric energy. In the driving device, it can move without mechanical contact, so that the transmission parts are not worn, thereby greatly reducing the mechanical loss, such as a linear motor driven maglev train. That's it.
(4) The rotating electric machine converts the rotary motion into a linear motion through a conversion mechanism such as a steel rope, a rack, a belt, etc., in the operation of the conversion mechanism, the noise is unavoidable, and the linear motor is operated by the electromagnetic thrust driving device. Therefore, the entire device or system has little or no noise and a good operating environment.
(5) Because the linear motor has a simple structure, and its primary core can be sealed with epoxy resin or the like after being embedded, it can be applied in some special occasions, for example, it can be used in wet or even water; it can be corrosive. It can be used in gas or toxic or harmful gases, and can be used at high temperatures of several thousand degrees or low temperatures of several hundred degrees.
