Product Description:
Bosch Rexroth Indramat produces the HMF01.1N-S0K1-M1200-N-480-NNNN, a passive line component in the HMF Motor Filters series. The module is installed between a servo inverter and its matched motor to attenuate high-frequency switching artifacts, limit voltage overshoot, and protect motor insulation in automated machinery. Through controlled impedance, it smooths the current waveform that reaches the motor terminals, helping meet electromagnetic compatibility targets and extend the operating life of connected rotating equipment.
It contains 3 single-phase chokes arranged in a star configuration, and each choke inserts series inductance on one phase to reduce the du/dt caused by PWM switching. The filter is wired on the motor output side of an IndraDrive amplifier, so no additional connections to the mains are required. Compatibility with three-phase AC drive systems ensures equal treatment of all phases and balanced voltage distribution. The magnetic circuit is sized for continuous operation up to 100 Hz fundamental frequency, allowing full-speed service for most industrial motors driven by vector control. During transient current surges, the inductive elements withstand a peak thermal and magnetic load of 165% without saturation, preserving voltage filtering performance while acceleration, braking, or regeneration peaks occur.
For enclosure layout, the unit is delivered as an open assembly rated at IP00; therefore, it must be placed inside a grounded control cabinet to avoid accidental contact with energized conductors. The preferred mounting orientation is vertical, which promotes unrestricted airflow along the laminated cores and helps maintain winding temperature within limits. Mechanical integrity during transport and machine shock is verified to 15 g, so the filter remains electrically stable when mounted near stamping presses or gantry axes. An integral touch guard covers the terminal block, providing an additional layer of protection during routine inspection and connection checks.
