Abstract

The invention provides a large-thrust linear motor and relates to the technical field of linear motors. The motor mainly includes a primary, a secondary, a motor frame, a guide mechanism, and a power output structure, and windings or windings and permanent magnets are distributed on the primary; permanent magnets are distributed inside the secondary: the primary and secondary There are more than 2 pairs of kinematic pairs, or the cross-section of the joint surface of the primary and secondary kinematic pairs is a closed figure. The secondary is distributed around the primary; by controlling the current of the winding on the primary of the motion pair, the motion side is made to move relative to each other to generate large thrust and torque. To solve the technical problems of large volume and low thrust in the prior art, the relative area between the primary and secondary can be effectively increased, and the thrust of the linear motor can be effectively increased. The motor has the characteristics of compact structure, small size, large output thrust and output torque, fast response speed and wide application.

Description

technical field [0001] The invention relates to the technical field of linear motors. Background technique [0002] The linear motor has been widely concerned since it was proposed. The general linear motion is achieved by converting the rotary motion into a linear motion through a mechanical conversion device. The appearance of the linear motor has changed this situation. The linear motor can directly convert electric energy into The mechanical energy of linear motion does not require an intermediate conversion device, which fundamentally eliminates the error generated by the intermediate conversion device. [0003] The thrust density of traditional linear motors is not high enough. When the thrust of the motor needs to be increased, the volume of the motor often changes greatly, which is not conducive to the miniaturization of the motor. Connection, the friction force is large during the movement process, and the power loss due to friction is also large in high-power appl...
