New Product: Brushless Dc Motors Have Electronics Built In

A line of brushless dc motors with a built-in single-quadrant speed controller include EC 20 flat, EC 32 flat, and EC 45 flat in two and five-wire versions with a 2 to 50-W operating range.

Current commutation is through Hall sensors. In the two-wire version, speed acts proportionately to the applied 10 to 28-V operating voltage. The five-wire version offers a wider operating range with setvalue input. Standard on all models is current limitation and under and overvoltage switch-off plus temperature monitoring.

A protective cover shields against contamination, making the units suitable for extreme environments.
