Portescap's Brushless Ironless DC Motors Feature Carbon Brush Communication Method

August 9, 2007—

Portescap's 25 mm brushless ironless DC motors feature a carbon brush communication method for increased efficiency in high volume manufacturing applications.

"Unlike the axial spring commutation configuration common to most brush DC motors, the 25mm brushed ironless DC motors offer a rotational spring that delivers constant spring force, extending brush life and minimizing motor sensitivity to vibration shocks." says Udayan Senapati, Portescap's product line manager.

The new commutation method coupled with a metallic front end and optional integrated EMC filter made the 25 mm brushless ironless DC motors suitable for operation in semi-conductor wafer handling and metrology and industrial equipment applications. Additionally, its power-to-size ratio is suitable for power hand tool applications.

Two versions are available, both 25 mm in diameter. The 25G is 53 mm in length, weighs 145 grams and provides 40 watts of power with 40 mNm continuous torque. The 25GST is 43 mm in length, weighs 111 grams and delivers 27 watts of power with 30mNm continuous torque.
