40ECP44 Slotless Brushless DC motor

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).

Product Highlights

  • Compact 40mm diameter by 44mm length
  • 4 poles for higher torque
  • Speeds up to 30,000 rpm
  • Lower power losses results in higher efficiency
  • No cogging torque for smooth rotation
  • Maximized performance/price ratio
  • Peak torque 1.1Nm during 2 seconds

Customization Available

  • Connectors
  • Custom shafts - flats, knurling, diameter, length
  • Coil modifications - resistance and inductance
  • Embedded temperature sensor
  • Dust protection sealing of cables output
  • Without hall sensors
  • Special lubricants
