Product Description:

The SV3403-01000 flux vector drive is manufactured by Kollmorgen within the SV3000 Flux Vector Drives series. This device is an AC motor controller used in conveyors, pumps, and other automated equipment where closed-loop speed regulation and high starting torque are required. By modulating output frequency and current, the drive maintains precise motor performance while protecting mechanical components.

The drive is housed in a NEMA 4/12 enclosure, so it resists dust, dripping liquids, and light washdown. Internally, an axial fan moves air across the heat sink to sustain the maximum ambient temperature of 40 °C during continuous duty. On the line side, it draws 6.9 A at full load and has an input power factor of 0.95, helping reduce reactive demand on the supply transformer. The inverter’s frequency reference can be adjusted in steps as fine as 0.02 Hz, enabling slow-speed tuning for positioning tasks. Its continuous output is rated at 3 HP, and elevation-related derating is unnecessary until the installation exceeds 3300 ft above sea level. During controlled deceleration, the braking transistor may be engaged for 5 s every 2 min, and the internal resistor can absorb 70% of motor torque under that duty cycle.

At the motor terminals, the drive can generate up to 120 Hz of output frequency, covering high-speed spindle or fan applications. Momentary demands are covered by a peak phase current of 7.2 A RMS, while the steady-state limit remains at 4.8 A RMS. The inverter section is sized for 4.3 kVA of apparent power, providing ample margin for overload events. Starting torque reaches 150% at 3 Hz, so fully loaded motors can accelerate smoothly from standstill without mechanical coupling aids. Brake control helps dissipate returned kinetic energy during deceleration, and thermal sensors monitor internal temperature to protect the power semiconductors during repeated stopping cycles.
