22ECT60 Ultra EC

22ECT60 Ultra EC Slotless Brushless DC Motor

22ECT60 Ultra EC Slotless Brushless DC Motor

22ECT60 Ultra EC

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.

Product Highlights

  • Small package, 2 standard lengths available
  • Proprietary high efficiency coil design
  • Access similar or higher torques than DC motors with much higher lifetimes
  • Best in class torque capability for BLDC motors in this size, using 4 poles design

Customization Available

  • Coil modifications - resistance and inductance
  • Connectors
  • Custom shafts - flats, knurling, diameter, length
  • Embedded temperature sensor
