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
