Brushless dc motors include integrated electronics for applications with limited space. The line includes EC 20 flat, EC 32 flat, and EC 45 flat with built-in speed controllers. The standard motors available are the 2-and 5-wire versions, with an operating range of 2 to 50 W.
Current commutation is integrated in the motor through Hall sensors, a 1-quadrant speed controller, and numerous protection functions. In the 2-wire version motors, speed acts proportionately to the applied operating voltage of 10 to 28 V. The 5-wire version has a wider perating range with set value input, enable, and speed monitor.
The EC 20 flat is available immediately in a 5 W version, with or without Hall sensors. The EC 90 flat has a two-channel encoder with 2,048 pulses per revolution for challenging positioning tasks.
