Patent number: 9641058Abstract: A linear motor includes a case, a magnet assembly and a coil assembly. The case is disposed along a first direction. The magnet assembly includes at least two first magnets, among which the first magnets are disposed corresponding to and between two first magnetic yokes, respectively. The coil assembly includes a winding coil having an exposed portion, among which the exposed portion is extended along a second direction and disposed between the two first magnetic yokes, and the exposed portion is at least partially overlapped with the two first magnets in a third direction. As a result, the coil assembly and the case are driven to reciprocate along the first direction by the winding coil due to the magnetic force, thereby solving the magnetic disturbing issue, enhancing the driving force of the linear motor, and optimizing the mechanical rigidity.Type: GrantFiled: January 23, 2014Date of Patent: May 2, 2017Assignee: DELTA ELECTRONICS, INC.Inventors: Ching-Hsiung Tsai, Hong-Cheng Sheu, Chi-Wen Chung, En-Yi Chu

Patent number: 9528581Abstract: A motor driven linear actuator comprises an electric motor, a ballscrew device, and a rolling bearing. The electric motor includes a motor shaft having a first end portion. The first end portion includes an end surface and a receptacle having a first accommodation space. The ballscrew device includes a screw having a first end portion coaxially connected to the first end portion of the motor shaft. The first end portion of the screw includes a first section to be accommodated in the first accommodation space for fixing the screw with the motor shaft. The rolling bearing is disposed between the electric motor and the ballscrew device for supporting the first end portion of the screw. The end surface of the motor shaft contacts and abuts against the rolling bearing for limiting the movement of the rolling bearing between the electric motor and the ballscrew device.Type: GrantFiled: December 30, 2013Date of Patent: December 27, 2016Assignee: DELTA ELECTRONICS, INC.Inventors: Ching-Hsiung Tsai, Chun-Chin Su, Chi-Wen Chung, En-Yi Chu

Patent number: 9506555Abstract: A hollow-type planet speed reducer includes a body. The body includes at least one driving gear driven by a power input source. The driving gear is connected to a transmission gear, and the transmission gear is connected to a first gear. Based on this, the output rotation speed can be reduced by the incorporation of the driving gear, the transmission gear and the first gear. Besides, a tubular member passes though the body and has an accommodating space to receive wires of the hollow-type planet speed reducer.Type: GrantFiled: December 23, 2014Date of Patent: November 29, 2016Assignees: Precision Machinery Research & Development Center, Delta Electronics, Inc.Inventors: Che Chien Chen, Jun Huang Lee, Han Pei Wang, Chin Hsiung Tsai, Chi Wen Chung

Patent number: 8115348Abstract: The present invention discloses a unit coil, a coil assembly and a coreless type linear motor. The unit coil includes bent subcoils arranged adjacent to one another and disposed on a non-acting side axially. The coil assembly includes tri-phase unit coil modules arranged in an operating direction, and the tri-phase unit coil module is composed of three identical unit coils alternately stacked and sealed by a resin layer, and the unit coil is formed by bending and stacking sub-coils. The bent sub-coils are stacked to a sufficient thickness or arranged to a sufficient width to achieve the desired driving force, and then a magnetic rail is provided to form a coreless type linear motor. In the aforementioned structure, the unit coil composed by an alternately overlapping layout method effectively reduces the required space of the coil assembly, and the sub-coils can be manufactured easily and will not be damaged easily.Type: GrantFiled: May 22, 2009Date of Patent: February 14, 2012Assignee: Chieftek Precision Co., Ltd.Inventors: Ming-Che Hsu, Chi-Wen Chung, Yung-Ho Hsiao, Wen-Jeng Wu
