power rating:
0.4 kw ~ more than 3000 kw (0.5 hp to more than 4000 hp)
vector control 1 (optimized vf control):
offering excellent vector control performance and insensitive to motor parameters.
startup torque: 0.50hz 180% rated torque
speed adjustment range: 1:100
speed stabilization precision: +- 0.5%
0.50hz controllable motor stable operation with 150% rated torque (large torque at low frequency).
vector control 2 (without encoder speed feedback, sensorless vector control, field oriented control):
precise speed sensorless vector control technology realizes ac motor decoupling, enabling the dc motorization of operation control.
startup torque: 0.25hz 180% rated torque (large torque at low frequency)
speed adjustment range: 1:200
speed stabilization precision: +- 0.2%
0.25hz controllable motor stable operation with 150% rated torque.
applications:
mechanics, winders, screw feeders, electronics, laminating machine (laminator), dividing and cutting machines (splitting machines, slitting machines), metallurgy, mining and coal, air compressor, petrochemical, transportation, building materials, municipal engineering..
