Motor polarity tests twin-stage and drives disk drive head suspension

摘要

Solve the problems, such as: this method and apparatus of test orientation to provide, motor are installed on disk drive suspension. ;SOLUTION: test is configured to: measurement electric signal, which is able to produce, is mounted on suspension 10 in response to relative motion by a pair of of motor 26 and 27; The electric signal of evident characteristics; And determine whether that at least one motor of any orientation is inverted relative to predetermined direction, according to feature electric signal. The test determines the orientation of two motor matches, the orientation, and no matter its direction is reverse, thus no matter is orientated and is mutually reversely. ;COPYRIGHT:(C) 2015, JPO& INPIT
