Three-phase Servo Motor Stabilizers

Three-phase servo motor stabilizers are perfect for working in complex situations, with high powers or a multitude of variations


They are equipment manufactured with the objective of offering a stable and efficient electrical supply to different machines and installations.

These three-phase servo motor stabilizers are formed by three single-phase stabilizers, each of them controls and modifies its corresponding phase, for this reason, we have a very effective tool against network imbalances, in addition to stable voltage, a fully balanced network.

The servo motor stabilizers have a microprocessor that controls the value of the input voltage at all times, processes it and orders the correct corrections to achieve the programmed value obtaining high precision.

The system used by IMA is a reference in the world of voltage stabilization, it consists as we have mentioned a microprocessor, it gives an order to a DC motor that acts on the cursor of an autotransformer toroidal, moving left and right by varying the tension.

This voltage is applied to the primary of the Booster that adds this voltage in phase or counter phase to the network through the secondary of the same, located in series to the phase. The IMA servo motor stabilizers have a Bypass switch to guarantee the possible maintenance without give up the power supply.

They have standard or optional protections to avoid over intensities, high or low voltages that could damage the equipment. These equipment can be used to stabilize the supply voltage of any equipment that, without needing an immediate response regulation, does require precise and constant stabilization, especially those that have a marked reactive character or with large intensity points.
