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.

摘要: Any one of the reversing portions of the flat cables is positioned in the sighting window when the inner case is in the neutral state. A prescribed mark is attached to the reversing portion which is positioned in the sighting window when the inner case is in the neutral state. Thus, it can be determined that the inner case is in the neutral state when the prescribed mark is attached to the reversing portion sighted through the sighting window.
