AC & DC DRIVE REPAIR SERVICE

What are DC Servo Drives?

Servo drives are electronic devices designed to control the operation of electric servomechanisms, most typically electric motors. Servo drives operate the motors by analyzing the signal from the motor feedback devices and continuously adjusting control signals to ensure desired motor performance within the closed loop system.

Unlike AC servo drives, DC servo drives convert Alternating Current (AC) into Direct Current (DC) to control the DC Servo motors they are paired to. Single-phase DC servo drives operate in half-bridge mode by generating a half cycle of DC output from a single phase of AC input. Three-phase DC servo drives are equipped with 6 SCR’s that allow them to operate in full-bridge mode to generate a DC output from a 3 phase AC input.

What are Variable Frequency Drives or Inverters?

A variable frequency drive (VFD) controls a motor’s velocity of rotation by modulating the frequency of the incoming AC voltage between the US standard 60 Hz all the way down to 0 Hz.  Depending on the application, VFDs can perform a continuously variable speed change or by switching between the preset speeds.Within the VFDs, this modulation is occurring in three stages:

1. The first stage rectifies the incoming Alternating Current;


2. The second stage charges a DC capacitor bank called the “DC Bus”;


3. The final third stage, driven by a microprocessor and commonly known as a “power inverter”, modulates the energy stored in the DC Bus in the form of a PRM output (typically a 4 KHz carrier) that allows you to control the motor speed and torque.
