Aug 5, 2025 · A v ariable frequency drive (VFD), often called an inverter, regulates the speed of an AC induction motor by varying the power supply''s frequency and voltage. Key takeaways:
Inverters are devices that convert DC power to AC power. They are used in a wide range of applications, from small appliances to large industrial machinery. A servo inverter is a specific type of inverter that is used to power servo motors. Servo inverters work by converting DC power from a battery or power supply into AC power.
Unlike servo drivers, inverters typically use open-loop control, meaning they do not rely on external feedback devices to monitor motor performance. Inverters are ideal for applications where speed control is essential but precision is less critical. Common uses include:
Servo inverters are typically more expensive than regular inverters, but they offer superior performance and reliability. They are ideal for applications that require precise control of the motor speed and position. 3. The benefits of using a servo inverter
Inverters work by converting the incoming AC power into DC power and then converting it back into AC power with variable frequency and voltage. By adjusting the frequency and voltage of the output power, inverters can control the speed of the motor.
Figure 1 Servo motors and drives are typically separate components connected by an expensive cabling harness providing power and control. But perhaps the most frustration results from the cabling. Servo motor cables are notoriously expensive, having to handle both control signals and high currents passing from the drive to the motor.
Servo drives (also referred to as servo amplifiers) can be either linear or switching types, depending on how power is delivered to the motor from the switching devices (typically IGBTs or MOSFETs) in the inverter section of the drive.
