Product Description:
The 10.Z2.F04-1003 is a three-phase motor choke produced by KEB within the Z2 Three Phase Motor Chokes series. Installed between a frequency converter and an induction motor, the component introduces controlled inductance to smooth current waveforms and limit voltage spikes generated by steep pulse edges. By reducing differential-mode interference, it helps drive systems meet electromagnetic compatibility targets and mitigates motor insulation stress in industrial automation lines that run at variable speeds.
The choke’s inductive reactance stems from its winding value of 1.5 mH, a magnitude selected to filter high-frequency harmonics without causing excessive voltage drop at the fundamental frequency. Continuous operation is supported at a rated load of 5.8 A, so drives that draw up to this current can be connected without additional derating. It is designed for a supply of 400 VAC, matching the common low-voltage three-phase power systems used on factory floors. When paired with high-speed spindle inverters, it maintains stable impedance up to an output frequency of 1600 Hz, preventing resonance throughout the modulation range. An impedance voltage of 20% indicates the percentage of nominal line voltage dropped across the choke at rated current and shows the expected converter headroom.
Copper terminals accept conductors up to 6 mm², allowing the wire size to match the rated current and thermal limits. Insulation materials can withstand a peak potential of 550 V, providing clearance above the nominal voltage to tolerate transient overvoltage from regenerating loads. Core and winding losses amount to 48 W at 800 Hz, providing data for enclosure ventilation planning when the choke is mounted inside a cabinet. The magnetic circuit supports three interconnected phases, ensuring balanced impedance on all lines and preserving symmetrical motor currents during scalar or vector control operation.
