Product Description:
The 22.Z2.F04-1003 is a three-phase motor choke manufactured by KEB within the Z2 Three Phase Motor Chokes series. The component is wired between a frequency inverter and an induction motor to limit the rate of current change, attenuate switching harmonics, and protect drive electronics from reflected voltage spikes. By adding series inductance to all three motor conductors, the choke stabilizes motor current waveforms and lowers acoustic noise in automated conveyors, pumps, and material-handling stations. It is intended for cabinet mounting inside industrial control panels.
This Z2 model is designed for a nominal line-to-line voltage of 400 VAC. Its insulation clearance supports operation up to 550 V, allowing the device to tolerate transient overvoltage events common on long cable runs. The winding can carry a continuous phase current of 115 A, allowing it to pair with medium-power inverters. A series inductance of 0.080 mH provides the impedance needed to smooth commutation edges, while a direct-current resistance of 3.7 mΩ keeps additional conduction loss low. Under these operating conditions, the choke introduces a 20% voltage drop, which drive-sizing software can account for when maintaining motor torque at the desired setpoint.
The terminals accept conductors up to 35 mm², matching the cable sizes normally selected for motor feeders carrying more than 100 amps. The laminated core and windings contain 6.2 kg of copper, contributing to a total assembled weight of 17.0 kg; this mass also increases thermal capacity during intermittent overloads. Heat generated by core and copper losses reaches 224 W at a switching frequency of 800 Hz and rises to 264 W at 1600 Hz, so the enclosure must provide adequate ventilation. Proper clearance around the choke helps heated air move away from the windings and prevents nearby panel components from restricting airflow.
