Electromagnetic design of integrated winding structure short-stroke DC planar motors

High precision planar motors have the features of simple system structure, planar direct drive, high resolution, fast response and have been widely noted in academic world and relevant areas for the past few years. However, the researches about systematic design method of planar motors are few in number. Integrated winding structure short-stroke DC planar motor (IWSDCPM) is analyzed in the paper. The structure, operation principle and features of the new type planar motor are introduced. The main dimensions' equation is derived and the main dimensions of the planar motor are confirmed. The design of coil and permanent magnet is discussed respectively, and the thrust optimization is carried on. According to its special structural style and applications, the universal design method of the planar motor is put forward. A prototype motor is manufactured according to the proposed design method, and some relational experiments are also achieved. The experiment results are agreed with the design objective. That verifies the validity of the design method.
