Gefran Quix GV drive delivers 100% torque at standstill
Gefran UK Ltd is launching a new range of high-performance sensorless AC variable speed drives in two package sizes covering 0.37-2.2kW that deliver full torque at standstill. After performing a static auto-tune routine with simple motor nameplate data for rated motor voltage, current and frequency, the Quix GV employs its patented 3GV open-loop motor control technology to deliver 100 per cent torque at 0.0 Hz. Furthermore, the vector control algorithm optimises dynamic response, energy saving and maximum torque delivery in real time, continually tracking motor inductance, resistance, current and power factor levels under dynamic application conditions.
