Crouzet has introduced the DCmind Brush range of direct current brush motors. These soundless motors, even under full load, offer exceptional efficiencies, long service life, and a wide range of gearboxes and accessories. The motors have a noise level of only 35db — 20db less than the current motor standard range. High quality magnets, brushes, and ball bearings, and special shaping and balancing of rotor poles result in a silent 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 product range includes 15W, 25W, and 55W motors with a 42mm diameter, and 55W and 104W motors with a 63mm diameter. DCmind Brush motors support 12V, 24V, and 48V power supplies and are available with several accessories and adaptations, including rear brake, optical or Hall effect encoders (1 or 2 channels), connectors and wires, voltage, speed and power, and shaft dimensions and material. Additionally, Crouzet’s eco-design strategy has cut the environmental impact of the product’s overall life cycle in half while at the same time improving the product’s energy efficiencies. The motor’s extremely low sound level meets IEC 60601-1 for medical devices. All new motors are approved in accordance with UL 10004-1, CE, and support IP56, IP67, and IP69K. They are also RoHS compliant.
