摘要： A single sided servo apparatus comprises a linear motor and a longitudinal carriage which is connected to the linear motor at one end thereof. The linear motor comprises a stator including field magnets arranged linearly and a movable piece including armature coils. The field magnets have a trapezoid-like magnetic flux distribution. An arrangement pattern of the field magnets has a relative tilted angle to an arrangement pattern of the armature coils, so that a free end of the carriage precedes the other end thereof connected to the linear motor. Then, the thrust has a small variation and generates a stable thrust of the servo apparatus.
