A magnetic field generating module includes a housing, a plurality of interpoles, a plurality of short poles and a plurality of windings. The housing has an annular section and an inner side. The interpoles disposed on the inner side in the housing are arranged around an inner periphery of the annular section with the same intervals. The short poles are disposed on the inner side in the housing and distributed between the interpoles evenly. A first interval is formed between the adjacent short poles, and a second interval equal to the first interval is formed between each of the interpoles and the adjacent short pole. The windings are respectively disposed corresponding to the interpoles and located between the interpoles and the short poles. The magnetic field generating module of the invention has more concentrated magnetic lines so as to prompt the magnetic flux density and the magnetic force.
