发明名称 Linear motor having improved magnetic characteristics
摘要 A linear motor having improved magnetic characteristics in driving a coil and in preventing flux leakage which is particularly useful with a magnetic disc memory. The motor includes a magnetic housing having top and bottom surfaces, side surfaces and one end surface with the end surface including integral first and second magnetic center pieces. An end plate mates with the magnetic housing with the end plate having integral first and second magnetic center pieces which mate with the first and second magnetic center pieces of the housing. First, second, and third magnets are mounted to the top and bottom surfaces and one side surface of the magnetic housing in cooperative relationship with the first center piece. Fourth, fifth, and sixth magnets are mounted to the top and bottom surfaces and the other side surface of the housing in cooperative relationship with the second magnetic center piece. A coil is coupled to the first and second magnetic center pieces and drives a carriage assembly.
