Crouzet Motors has introduced a short, yet extremely informative video that dramatically demonstrates the whisper-quiet operation of its innovative new DC Brush Motor line. The video tests and measures the sound levels of the Crouzet DCmind Brush motor versus conventional DC brush motors, and also evaluates the sound levels when used with gearheads. The results: the DCmind brush motor measured 15 decibels (dB) quieter in stand-alone operation compared to a conventional DC motor. The DCmind motor, when used with the special low-noise DCmind gearbox, also measures demonstrably quieter than a standard DC motor used with a conventional planetary gearhead.

"A video with good audio and a dB meter is really the only way to appreciate the virtually soundless operation of this motor without hearing it in person," said John Morehead, National Sales Manager for Crouzet Motors. "With its amazingly quiet operation and high efficiency, it really is a revolutionary product, especially for applications where low noise level, long battery life and extremely long service life are critical."

Because of its noiseless operation, the DCmind Brush motor series is particularly well suited to applications in medical, laboratory, commercial and industrial equipment. In addition to its low sound level, the motor meets several standards in applications for medical (IEC 60601-1), office equipment (IEC 60950), and household appliances (IEC 60335). All the DCmind Brush motors are approved in accordance with UL 10004-1 and CE, and are RoHS compliant. They come with standard IP65 levels of environmental protection and can be made available in IP67 and IP69K versions. DCmind Brush Motors can also be used in a variety of other applications such as pumps and valves in mass transportation equipment.

The DCmind Brush motors' operating sound level of as low as 35 dB is about that of a whispered conversation. Key to its silent operation is the use of high quality magnets, brushes and ball bearings as well as special shaping and balancing of rotor poles. These factors combine to dramatically reduce the energy dissipated through vibration and resonance levels. The result is not only the quietest brush motor on the market, but also a motor with more than 80% efficiency and a minimum service life of 5,000 hours when used with normal power loads. Under reduced load conditions, service life can be increased to as much as 24,000 hours.

The DCmind Brush motor product range includes 15, 25 and 55 watt motors with a 42mm diameter, and 55 and 104 watt motors with a 63mm diameter. DCmind Brush motors support 12, 24 and 48 volt power supplies and are available with several accessories and adaptations, including rear brake, optical or Hall effect encoders (1 or 2 channels), connectors and cables, as well as custom voltage, speed and power, and shaft dimensions and material.
