Product Description:
The 23.Z2.F04-1003 is a three-phase motor choke produced by KEB for the Z2 Three Phase Motor Chokes series. Installed at the output of a variable-frequency drive, the choke inserts controlled impedance into each phase, smoothing current spikes and reducing conducted electromagnetic interference. By limiting edge rates and transient overvoltages, it helps prolong motor insulation life and minimize bearing stress in automated conveyor lines, presses, and packaging machinery that rely on fast-switching IGBT inverters.
An inductance of 0.082 mH provides the reactive impedance needed to filter high-frequency harmonics without creating excessive voltage drop. The windings are sized for a continuous current of 150 A, allowing the choke to serve medium-power drives while remaining within its thermal class. The choke is designed for a nominal line voltage of 400 VAC and has an impedance voltage of 20%, balancing harmonic attenuation with the available motor voltage. Dissipative losses reach 264 W at full load, so the installation must provide adequate panel airflow. Copper conductors with a cross-sectional area of 50 mm² carry the high RMS current while limiting resistive heating. These electrical characteristics allow the choke to reduce steep current transitions between the inverter and motor without placing unnecessary impedance in the power path.
The choke supports a maximum output frequency of 1600 Hz, making it compatible with high-speed spindle and servo applications. Power lugs use an M10 thread, and a tightening torque of 20 Nm helps maintain low-resistance electrical joints. The unit has an overall mass of 32.0 kg, distributed across a laminated core with a height of 170 mm that fits below many standard busbar runs. The assembly withstands up to 550 V line to line and does not include an integral temperature switch. Its three-phase arrangement connects directly between a compatible variable-frequency drive and motor without requiring separate balancing reactors. Adequate mounting support is necessary because of the unit’s mass, while sufficient clearance around the windings and core allows heat from normal operation to dissipate into the cabinet airflow.
