HV500 series high-performance frequency converter: a new generation of high-performance vector converter launched by Hopewindelectric, using a new high-performance open-loop vector control technology, support asynchronous motor and permanent magnet synchronous motor drive control; High quality, strong performance, high power density design, enhanced the product in industrial applications in the environment of ease of use, reliability, Environmental Adaptability, functional diversity, application flexibility and other advantages, upgrade the design standards, optimize the installation space, upgrade the user experience from various aspects.
High Torque Response
When the rated torque is applied suddenly in torque control mode, the current response time is about 2MS
the excitation current is highly decoupled from the torque current, the load capacity is strong, the speed range is wide, and the dynamic performance is excellent
Flux Linkage Observation And Velocity Estimation
A full-order closed-loop flux obser ver is used to adaptively identify the rotor speed and stator resistance based on the stator current estimation error and rotor flux estimation value. It overcomes the error caused by the parameter variation and integral drift of the openloop speed estimation motor, reduces the sensitivity to the motor parameters, and makes accurate flux linkage observation and speed estimation model, oLVC control mode to ensure 0.5 Hz 150% high starting torque, and open-loop zero-speed hover function
