High Frequency When others can t take the pace, FEIN high-frequency power tools crank it up. FEIN High-Frequency Power Tools have been proven to be a superior design type many areas of dustry and manual trades where power tools are expected to deliver contuously high output. Extremely reliable power tools are needed for contuous operation areas like metal processg, heavy-duty grdg, roughg, and cuttg. FEIN High-Frequency Power Tools have high power reserves that average about 100% above the rated value. Speed remas constant across the entire load range. This means that the tools always work with the most ideal operatg speed, high grdg power, and low grdg-disc wear. Our products are specifically designed with the quality needed to generate permanently high performance contuous operation. For these reasons, FEIN High-Frequency Power Tools are constructed to meet maximum requirements terms of design and quality. The FEIN High-Frequency product le contas a large selection of angle grders and straight grders for professional users the manual trades and dustry. You will fd more formation about the FEIN High-Frequency le a separate catalogue. Please contact us for a copy.

High Frequency What is High Frequency? In electrical engeerg, high frequency refers to any frequencies above 10 khz. In the case of power tools, however, this term generally refers to all power frequencies that are higher than standard power frequencies (50/60 Hz). A frequency of 300 Hz is the most popular for high cycle tools today. To operate these tools, special generators are needed to brg the power to the elevated frequency from 440 volt 3 phase (575 volt 3 phase Canada) to 200 volt 300 Hz. The high frequency tools are 3 phase squirrel cage duction type motors that do not require the normal wear parts. Speed comparison based on output. Green: Pneumatic Blue: Standard frequency Orange: High frequency Grdg High frequency it s simply better. What are the advantages of high frequency? The most important advantage lies the constant speed and torque which provides more power. By creasg the frequency from 50/60 Hz to 300 Hz you crease the motor speed. The creased motor speed when used conjunction with FEIN s excellent gear reduction provides you with the ideal constant speed for work like heavy duty grdg. In addition, the motor s output power rises directly proportional to the elevated frequency without addg weight or size: At 300 Hz, power creases five times because this frequency is five times as high as regular 50/60 Hz. Cut-away view of an encapsulated, surface-cooled, high-frequency motor. The benefits of FEIN Powerful and simple design for extremely long life. Highly efficient performance. Mimal wheel speed loss under heavy load. High torque. Low wear. Significantly less expensive to run than a pneumatic system*. Low matenance and repair costs. Low tool wear. Low system matenance requirements for the system. * Energy costs up to 10 times lower than for pneumatics. (results of an vestigation by an dependent stitute). 135

High Frequency Frequency Transformers FEIN Frequency Transformers are designed to comply with protection class IP 54 accordg to DIN 40 050 and have coils of sulation class F accordg to DIN VDE 0530. They are virtually matenance free. The ball bearg matenance terval is approximated at 20,000 operational hours. The frequency transformers are easy to set up. The place of stallation must only have unimpeded air supply and draw (maximum temperature +40 C). We recommend stallg power sizes 7.5 kva and higher on rubber-metal buffers order to mimize vibration durg operation. FEIN KSR frequency transformers are asynchronous-synchronous frequency transformers. Even under load, output voltage deviates only a small amount (± 1%) from the set idle speed. The transformers are short-circuit proof. It is common practice to connect several KSR transformers of same types and sizes series.
