22ECT82 Ultra EC Slotless Brushless DC Motor

22ECT82 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 small dc motors are capable of delivering 2 times higher continuous torque than comparable BLDC motors of same size over the entire low speed range when used with gears.

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
