Servo Drives System

Listing ID #3869089

Spindle motor repair naturally compliments servo repair. Spindle motors use servo technology to run closed loop. All considerations for servos apply to spindles; in some respects spindle motor repair can be even more intricate. Spindles endure an intense evaluation specifically tailored to their characteristics. We obtain a comprehensive understanding of the spindle motor's condition not only to fix what is broken, but also to fine tune the motor for optimum performance. It is our goal to retrofit, Rewinding. Repair your spindle motor back to "Like New" condition.

Spindle motors require specialized skills and tools in order to complete effective repairs. It is important for any company that repairs spindle motors to have precision measuring devices to check mechanical tolerances, balance, and feedback signal integrity.

Electronic motion control is a multi-billion-dollar industry. Servo motion is a fraction of that industry, sharing it with non-servo motion, such as stepper motors and variable-frequency systems. A servo system is defined here as the drive, motor, and feedback device that allow precise control of position, velocity, or torque using feed-back loops. Examples of servomotors include motors used in machine tools and automation robots. Stepper motors allow precise control of motion as well, but they are not servos because they are run "open-loop," without tuning and without the need for stability analysis.

The most easily recognized characteristic of servo motion is the ability to control position with rapid response to changing commands and disturbances. Servo applications commonly cycle a motor from one position to another at high rates. However, there are servo applications that do not need fast acceleration. For example, web-handling applications, which process rolled material such as tape, do not command large accelerations during normal operation; usually, they attempt to hold velocity constant in the presence of torque disturbances.

Servo systems must have feedback signals to close control loops. Often, these feedback devices are independent physical components mechanically coupled to the motor; for example, encoders and resolvers are commonly used in this role. However, the lack of a separate feedback device does not mean the system is not a servo. This is because the feedback device may be present but may not be easily identified. For example, head-positioning servos of a hard-disk drive use feedback signals built into the disk platter rather than a separate feedback sensor. Also, some applications use electrical signals from the motor itself to indicate speed. This technology is often called sensor lesser though the name is misleading; the position is still sensed but using intrinsic motor properties rather than a separate feedback device.
