Patent number: 9172285Abstract: The present invention relates to a linear stepping motor, the motor characterized by: a housing; a stator mounted inside the housing: a rotor rotatively arranged at an inner surface of the stator and mounted with a female screw threaded to a lead screw; a mounting plate fixed at a lateral surface of the housing for passing the lead screw; and a plate cover coupled between the mounting plate and the housing configured to prevent a bearing rotatively supporting the female screw from axially moving, such that the bearing can be securely fixed in a simple structure by the plate cover itself to allow a free design in the size of a central hole of the housing or the size of an outer diameter of a magnet regardless of the size of outer diameter of the bearing, and the bearing is securely fixed to the plate cover by caulking to prevent the bearing from moving axially, whereby vibration and noise can be remarkably reduced to enhance the reliability of the product.Type: GrantFiled: April 8, 2010Date of Patent: October 27, 2015Assignee: LG INNOTEK CO., LTD.Inventor: Yu Man Won

Patent number: 8816560Abstract: Disclosed is a canned motor for restraining a cogging torque from being generated by inserting magnetic metal pins into slot openings of a stator, thereby reducing noise and vibrations during an operation of the canned motor. The canned motor includes: a can inserted into a housing to seal a coil mounted within the housing; and a stator installed on an outer peripheral surface of the can and inserted along an inner peripheral surface of the housing. A plurality of fixing guides protrude from an outer peripheral surface of the can and metal pins are inserted into the fixing guides to be integral with the fixing guide, such that the metal pins are inserted into and attached to slot openings of the stator when inserted into the stator.Type: GrantFiled: July 11, 2012Date of Patent: August 26, 2014Assignees: Hyundai Motor Company, Kia Motors Corporation, Myunghwa Ind. Co., Ltd.Inventors: Seung Yong Lee, Jea Woong Yi, Chi Myung Kim, Hark Koo Kim, Yun Seok Kim, Yong Sun Park, Bong Sang Lee, Tae Sung Oh, Yu Man Won
