摘要： Disclosed is a linear motor that can exert a high propulsive force and reduce cogging. A stator has a plurality of core units in a stroke direction. Each of the core units has a first core having a first magnetic pole and a second magnetic pole, which is different in polarity from the first magnetic pole, coils wound around the first core, a second core having a third magnetic pole and a fourth magnetic pole, which is different in polarity from the third magnetic pole, and coils wound around the second core. The third magnetic pole faces the first magnetic pole, and the fourth magnetic pole faces the second magnetic pole. A movable element is sandwiched between the first magnetic poles and the third magnetic poles, and between the second magnetic poles and the fourth magnetic poles.
