35ECS80 Ultra EC Slotless Brushless DC Motor

35ECS80 Ultra EC Slotless Brushless DC Motor

35ECS80 ULTRA EC

Part of our Ultra EC slotless brushless motors, the ECS line of high performances motors are design optimized to sustain extremely demanding repetitive working cycles. The two pole 35ECS80 brushless motor provides high continuous and peak speeds at low voltage while maintaining smooth operation and long life. With the 35ECS80, you can get the right balance between high torque and speed in a compact package. Even better, is the 35ECS80's adaptability for most applications in the power hand tool & industrial markets, enhancing life and reliability.
