16N78 Athlonix Brushed DC Motor
Portescap
Brushed DC Motor
The 16N78 Athlonix high torque DC motor design combines high power density and precious metal commutation. This coreless DC motor can deliver a torque up to 6 mNm continuously and reach up to 80% efficiency while maintaining a long lifetime. Mclennan hold many models in stock for immediate delivery and any motor from Portescap can be obtained on short lead times. For more information contact our Sales and Applications Engineering team.
