Abstract

The invention disclose a displacement control mode of a rotor of a direct-drive switched-reluctance planar motor, belongs to the field of electromechanical control researches, and specifically relates to a displacement control of a rotor of a direct-drive switched-reluctance planar motor. The displacement control mode disclosed by the invention is characterized in that the displacement motion of a rotor 7 of a direct-drive switched-reluctance planar motor is changed cyclically, and the cycle of motion of the rotor 7 is equal to the pole pitch of a stator 9 and is 12-24 mm; and through dividing each cycle of motion into six equal parts, the control mode disclosed by the invention has the advantages that the power-on states of rotor windings are determined according to six different positions of the rotor 7 relative to a stator 8, because the cycle of motion of the rotor 7 is equal to the pole pitch of the stator 9, each rotor winding is equal in power-on time and displacement, so that the rotor 7 operates stably, thereby facilitating the accurate positioning of the rotor 7; and two phases of rotor windings are power-on simultaneously, so that the electromagnetic thrust of the rotor 7 is increased, and the running speed of the rotor 7 is increased.

Description

technical field [0001] The invention discloses a method for controlling the mover displacement of a direct-drive switched reluctance planar motor, which belongs to the field of electromechanical control research, and specifically relates to the mover displacement control of a direct-drive switched reluctance planar motor. Background technique [0002] The direct-drive switched reluctance planar motor is a mechatronic device that has self-starting capability in the x-direction and y-direction of the plane, and can directly drive the mover to do planar motion. It fundamentally gets rid of the "low-dimensional motion mechanism superposition The model of forming a high-dimensional motion mechanism can be used in plane welding machines, large-scale integrated circuit processing and packaging, printed circuit board production, probe monitors, plane measuring instruments, robot drives and other fields. [0003] Due to the complexity of the structure and arrangement of the stator an...
