40ECP55

40ECP55 Slotless Brushless DC motor

40ECP55 Slotless Brushless DC motor

40ECP55

The 40ECP55 brushless DC slotless motor is an optimal choice for high speed & peak torque applications. In addition to multiple brushless benefits (longer lifetime & higher peak torque), the slotless design allows for higher speed (30,000 rpm). This makes the 40ECP55 a great alternative to brushed DC and slotted BLDC motors thanks to an innovative assembly process and cost optimized design. The integrated fan provides active cooling during the motor’s operation, for continuous operation up to 0.15Nm at 30,000rpm (420 W), and achieving 1.1Nm peak torque during 2 seconds. This 40mm BLDC motor is also available without a fan (40ECP44).

Product Highlights

  • 40mm diameter by 55mm length
  • Integrated self-cooling fan
  • High power at 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

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