Stator structure of motor

摘要

A stator structure for a motor of high precision which suppresses the influence of electromagnetic noise between windings (4) and a distribution pattern layer (13a) in a printed board (1). A shield (12b) is provided between the windings (4) and the distribution pattern layer (13a) of the printed board (1) to shield the electromagnetic noise and suppress the influence of the electromagnetic noise to thereby enable precise control of the motor. A multilayered printed board (1) is arranged on an axial end face of the stator core (2) and the windings (4) are formed around the stator core (2) and the multilayered printed board (1) to enfold them toroidally in a regular winding manner. The multilayered printed board (1) comprises the distribution pattern layer (13a) for connection with the windings (4) and the shield layer (12b) for shielding electromagnetism between the distribution pattern layer (13a) and the windings (4).
