Brushed Ironless DC Motors
Portescap introduces its 25 mm brushed ironless DC motors that feature a carbon brush commutation method for high volume manufacturing applications. This commutation method coupled with a metallic front end and optional integrated EMC filter make these motors suitable for rugged operation in semiconductor wafer handling and metrology and in industrial equipment applications. Their optimized power to size ratio is appropriate for power hand tool applications where the weight of the hand tool directly impacts operator comfort and efficiency. Two versions are available: The 25G is 53 mm in length, weighs 145 grams and provides 40W of power with 40 mNm continuous torque. The 25GST is 43 mm in length, weighs 111 grams and delivers 27W of power with 30 mNm continuous torque.
