Variable speed drives (VSDs), also called variable frequency drives, are a valuable tool for energy management. VSDs are used in connection with pump and fan applications to vary the pump or fan speed according to demand, often with large savings in energy use. A VSD system typically consists of a three-phase AC induction motor and a variable frequency power supply.
Inverters, also called AC Drives or VFD (variable frequency drives), are electronic devices that can turn DC (direct current) to AC (alternating current). It is also responsible for controlling speed and torque for electric motors. An inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor.
OMRON inverters can control induction motors and synchronous motors. A few helpful functions:
- Inverter overload detection: to protect both the inverter and motor from burning.
- Torque boost (torque compensation): manual or automatic torque adjustment available.
- Inverter overvoltage detection and braking function: to prevent dangerous overvoltage.
