The HMF Motor Filters from Bosch Rexroth IndraDrive comprise a range of motor-side filter units designed to condition the PWM output of compatible drives for cleaner motor supply and improved system integration.
The series is offered in multiple variants that are selected to match the installation method, filter class, motor-frequency class, and switching-frequency range used by the drive system. Electrical sizing is defined by the filter’s nominal current rating and voltage class, allowing the unit to be specified for different load levels and DC-bus voltage categories. The platform also provides configuration choices tied to enclosure and protection requirements, so the filter can be integrated into different cabinet and machine environments. Overall, HMF filters are intended to be selected as an application-matched output-filter solution within IndraDrive installations where controlled motor-side electrical behavior is required.
