Claims

[Scope of utility model registration request]

Each N is made of neodymium/iron-based magnets coated with a thin film to prevent rust by electrodeposition.
A field magnet is formed by including P (P is an integer of 2 or more) permanent magnets with poles and south poles so that adjacent magnetic poles have different polarities, and a mover is placed at a position facing the field magnet. An armature is formed by arranging n (n is an integer of 2 or more) armature coils along the moving direction, and either the field magnet or the armature is attached to a mover that moves relatively. , the other being a stator.A linear DC brushless motor.
