The term Inverter refers to Variable-frequency drive (VFD) and is a type of adjustable speed drive used in elecrto-mechanical drive systems to control AC motor speed and torque. It works by varying the motor input frequency and voltage.
Inverter driven overhead cranes have several key benefits:
- Inverters keep the load on an overhead crane from swinging
- Provide smooth acceleration and deceleration
- Control the descendent speed
- Detect overload
- Enables the possibility of multiple speed settings
