22ECT60 ULTRA EC
Portescap
Slotless Brushless DC Mini Motor
The 22ECT Ultra EC is designed specifically to deliver ultra high torque in a compact size. The 22ECT is specifically optimized for high continuous torque at low to medium speeds, maximizing power between 10 K and 20 K rpm. These motors are capable of delivering 2 times higher continuous torque than comparable BLDC motors of same size over the entire low speed range, that includes typical conditions of use with gear trains.
