July 16, 2007 - WEST CHESTER, PA – 25mm Brushed Ironless DC Motors from Portescap, a Danaher Motion company, now feature a unique carbon brush commutation method to deliver long life and operational efficiency in high volume manufacturing applications.
“Unlike the axial spring commutation configuration common to most brush DC motors, 25mm Brushed Ironless DC Motors from Portescap offer a rotational spring that delivers constant spring force, which extends brush life and minimizes motor sensitivity to vibration shocks,” says Udayan Senapati, Ph.D, Portescap Product Line Manager.
The new commutation method coupled with a metallic front end and optional integrated EMC filter make 25mm Brushed Ironless DC Motors well suited for rugged operation in semiconductor wafer handling and metrology, and industrial equipment applications. Additionally, their optimized power to size ratio is ideal for power hand tool applications where the weight of the hand tool directly impacts operator comfort and efficiency.
Two versions are available, both 25mm in diameter. The 25G is 53mm in length, weighs 145 grams and provides 40 watts of power with 40 mNm continuous torque. The 25GST is just 43mm in length, weighs 111 grams and delivers 27 watts of power with 30 mNm continuous torque.
