380V Sensorless AC Motor Vector Control Drive for CNC Machine

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

Features of 303 series CNC application

Features	Benefits
Wide speed ratio	W/O PG vector: 1:100, W/T PG vector: 1:1000
Terminal-Peripheral equipment control	Control start/stop with the contact or button to simply realize the automation control of the entire equipment system.
Vector control 0	Real time estimates speed information of the motor only, without feedback control, real-time closed-loop control of the current all the way, 0.50 Hz outputs rated torque of up to 150%, track load change and limit output current automatically to make it not exceed the permitted maximum current value.No overcurrent error even if load mutation, rapid acceleration and deceleration to realize high performance and high reliability configuration of the universal Inverter.
Vector control 1	Not only real time estimates speed information of the motor, but also conduct feedback control, real-time closed-loop control of both the speed and current all the way, which can realize not only speed control but also torque control, and can translate universal AC induction motor into AC speed regulation motor and AC torque motor by adopting such kind of drive mode. This is a real vector control Inverter without external speed sensor.
