Product Description

Bosch Rexroth is an international engineering firm that designs motion control accessories.

The HMF01.1N-S0K1-M1200-N-480-NNNN is a high quality motor filter produced by the company. This motor filter is able to reduce decay current, voltage stress, and leakage current in servo motors. The filter is able to smooth out the voltage at the output of the motor. This ensures that a sinusoidal voltage is present at the motor output. Servo motors and variable frequency drives are operated on three-phase pulses that contain very sharp edges with high frequency. Even though the current is low, the high frequency interacts with the motor rotor and with the ground currents through motor bearings. This can cause a continuous hammering or chiseling effect on the motor's rotor and cause it to deteriorate it over a period of time. This problem can cause performance deterioration, eventual sparking, and might lead to catastrophic failure. This motor filter removes this risk by smoothing these high frequency pulse signals.

The HMF01.1N-S0K1-M1200-N-480-NNNN is also used to control pulse edges that pollute the machine ground with sharp transients. The filter is used to suppress signals that are strong enough to cause interference in the equipment electronics and induce electrical overstress (EOS) in machines. The HNF motor filter can also reduce electrical noise that causes data errors, random equipment behavior, and complete lockup of the equipment. If not controlled properly, electrical noise can alter sensor readings and affect computerized equipment. Reduction in electrical noise not only reduces currents in bearings but also reduces high frequency voltage in the machine overall. When using this filter, the long cables between motors and controllers don't induce noise in adjacent wiring. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
