Servo Stabilizer for Motors: Selection Guide
A motor load can place short-duration demands on a stabilizer well above its running current. Selection must cover the starting event as well as continuous operation.
Estimate the running load
Use measured electrical input or nameplate voltage and current where available. If using shaft power, account for motor efficiency and power factor. Include other motors and auxiliaries that run simultaneously.
Check the starting method
Direct-on-line, star-delta, soft starter and variable-frequency drive arrangements create different demands. Provide starting current, duration, number of starts and acceptable voltage dip to the stabilizer supplier; avoid a universal motor multiplier.
Confirm the supply range
Verify capacity at minimum input voltage, phase imbalance, overload duty, cooling and bypass. A stabilizer does not replace a motor starter, overload relay or drive. Confirm compatibility with drive and control equipment.
