40ECP44 Slotless Brushless DC motor
40ECP44
The 40ECP44 brushless DC slotless motor combines numerous brushless technology benefits (longer lifetime & higher peak torque) with slotless technology benefits (higher speed – 30,000 rpm, no cogging). This makes the 40ECP44 a great alternative to brushed DC and slotted BLDC motors thanks to an innovative assembly process and cost optimized design. The 40ECP44 motor can sustain peak torque during 2s up to 1.1Nm and up to 145W continuous power. This 40mm BLDC motor is also available with an integrated cooling fan (40ECP55).
