Miniature brushless motors offer low electrical noise profile
23 September 2010
Rotalink has introduced a line of miniature brushless motors with nominal output torque to 250mNm and maximum power ratings to 270W. The BL motor range is available in both 12 and 24Vdc versions, complete with three phase hall effect commutation for smooth and precise speed and/or position control. The efficient brushless design has an inherently low electrical noise profile and, unlike brushed dc motors, is not prone to commutation sparking, so the motor is suitable for EMC sensitive applications. There are five frame sizes with nominal diameters of 29mm, 32mm, 45mm, 57mm and 65mm.
The new BL brushless motors are matched for use with the brushless version of Rotalink's drag-and-drop/flow chart programmed Red Drive motor driver and controller, which significantly reduces the entry costs for high performance yet easy-to-use brushless servo control. The BLDC Red Drive has a 10A current rating and is complete with hall sensor inputs for brushless commutation, incremental encoder feedback inputs plus 27 programmable TTL level I/O pins for analogue and digital machine interfacing.
