Product Description
dU/dt filter
dU/dt filters dU/dt filters reduce the voltage peaks and the dU/dt of the pulses at the motor terminals. To some extent, the voltage at the motor terminals is still pulse-shaped; the motor current is sine-wave-shaped without commutation spikes.
Maximum cable length with dU/dt filter is 150 m.
Output filters in general Output filters are used for reducing the voltage stress on the motor windings and the stress on the motor insulation system as well as for decreasing acoustic noise from a frequency-controlled motor.
