Vector Control AC VFD Drives with 3 Phase 380VAC for CNC Lathe
A CNC lathe is a machine tool designed to remove material from a rotating work piece, using a cutting tool. Some lathes can form hollow parts by a process called metal spinning. These parts have circular cross-sections. Metal and other materials can be turned on a lathe, including wood and plastics. CNC controlled lathes use a computer to control the process of making each part with repeated accuracy and precision.
Application Challenges
· Precise speed regulation and torque over wide speed range
· Interlock drive with operation of CNC.
· Quick acceleration even under high torque conditions

Tips:
A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
