Model No.: BD338
BD338 Product Overview
BD338 series high performance rotary lathe dedicated inverter is of high speed digital control chip and advanced control algorithm. This inverter is specially designed for the rotary lathe market and featured with fast response, high torque at low speed etc. It is able to output 180% of the rated torque in 0.5Hz.
◆ The starting torque is high enough against complicated rotary objects. Strong rotary torque and uniform output are guaranteed when motor cuts heavily at low speed. The inverter also ensures the stability of rotary-cut and restart working of sudden stop at high speed.
◆ Through real time high speed dynamic operation, rotary thickness is always kept around the set point or normal rotary values within ±0.1mm of error precision. Machines with excellent mechanical lubrication and precise bonding process could decrease error into ±0.05mm.
◆ Super decelerating and breaking power guarantee the requirement of knife`s sudden stop at high speed.
◆ High adaptability: In consideration of in-field use features of rotary lathe, its normal operation could be realized with wide range design of working voltage, constant output torque in fluctuate voltage and 60% of rated voltage. This technology will be extremely outstanding in circumstances of violent grid fluctuation.
◆ Adjustable Wide Velocity Range: Fast rotary speed, high efficiency, satisfaction of application in fields with superior requirements of plate line speed
◆ Various combinations of sensors are provided to meet customers` needs ultimately.
