The invention relates to a long stroke linear motor based on power partition. The long stroke linear motor comprises primary stators, secondary rotors, a motor base and a fixing frame; the secondary rotors are arranged between the primary stators which are applied in pair; the primary stators are fixed to the motor base through bolts, and the secondary rotors are rigidly and fixedly connected to the fixing frame; the motor base is provided with two slide rails, and the fixing frame moves along the slide rail through pulleys; the number of the primary stators is n pairs, n is bigger than or equal to 4, and the primary stators are arranged to a straight line from front to back in sequence; output power P of the part corresponding to the ith pair of the primary stators meets the formula that P=Pi=F.vi. In the long stroke linear motor based on the power partition, a power partition technology is adopted, according to driving requirements of an application scene, rated power of each part of the long stroke linear motor is reasonably designed, and on the condition that application requirements are met, size, weight and manufacturing cost of the long stroke linear motor are drastically reduced.
Description
technical field [0001] The invention relates to the technical field of linear motors, in particular to a long-stroke linear motor based on power segmentation. Background technique [0002] Long-range linear motors are used for the launch of space vehicles such as space shuttles, aerospace aircraft, and single-stage reusable vehicles into orbit. They have the characteristics of low launch cost, high controllability and safety of the launch process, and strong versatility. In order to save the mass of the propelling part of the vehicle and reduce the cost, it is necessary to increase the launch exit velocity as much as possible. Considering the anti-overload capability of the equipment on the carrier and the power limit of the instantaneous high-power inverter, the average acceleration cannot be too high, which leads to a long acceleration distance of the launch system, usually reaching several kilometers or more. Therefore, the launch system of the vehicle needs to use an ul...
