Brushless DC Motors & Matching Drives

22ECP45 ULTRA EC

Slotless Brushless DC Mini Motor

The ECP line of miniature motors are ultra cost optimized without compromising on premium performance. The 22ECP45 provides high continuous and peak torques with limited core losses over a wide range of working speeds, and without friction or brush wear. With the 22ECP45, you can get the right balance between torque and speed to suit most applications.
