MOTOR POLARITY TESTING OF A DUAL STAGE ACTUATED DISK DRIVE HEAD SUSPENSION
Methods and apparatus concern testing a disk drive suspension. Testing includes moving a first portion of a suspension relative to a second portion. A pair of motors is mounted on the suspension. The testing further includes measuring an electrical signal that is intrinsically produced by the motors...

| description | Methods and apparatus concern testing a disk drive suspension. Testing includes moving a first portion of a suspension relative to a second portion. A pair of motors is mounted on the suspension. The testing further includes measuring an electrical signal that is intrinsically produced by the motors, combined in a circuit, in response to the relative movement. The testing further includes identifying a characteristic of the electrical signal and determining whether an orientation of one or both of the motors is reversed relative to an intended motor orientation based on the characteristic of the electrical signal. The testing can determine whether the orientation of both motors matches the intended motor orientation, whether the orientation of one motor is reversed in a same polarity condition, whether the orientations of both motors are reversed in a mutual reverse polarity condition, or whether the suspension has a mechanical or electrical defect. |
