Brushless DC Motor
Maxon Motor (Fall River, MA) is launching a range of flat brushless DC motors with integrated electronics. The EC 20 flat, EC 32 flat and EC 45 flat motors with integrated electronics reduce the user’s need for control input to the absolute minimum. Motors are available in two-wire versions with sp - e ed proportional to the applied operating voltage of 10 to 28 volts.
A five-wire version offers ad d i tional functionality and a wider operating range with set value input, enable and speed monitor. Current limitation, under and over-voltage switch-off plus temperature monitoring are standard in all models. The motors have an operating range of 2 to 50 watts. They are suited for use where there is minimal installation space, and where long service life and constant speed are required.
