Compact Speed Controller For Brushless DC Motors Without Hall Sensors

Fall River, MA -- The DECS 50/5 (Digital EC Controller Sensorless) is a new controller for driving brushless DC motors without Hall sensors. Typical sensorless drives such as pumps and fan applications can now easily be created thanks to modern technology and expert integrated controlling algorithms. maxon’s newly developed speed controller is particularly impressive through its performance, price and size.

The wide input voltage range of 10 to 50 V means that the DECS 50/5 is very flexible and adaptable. In continuous operation, an output current of 5A of the power stage is permissible, giving it a maximum output performance of 250 Watts – all this with it only being the size of a business card. The speed value can be set via an integrated potentiometer or an analog set value. The 1-Q amplifier can be operated at up to a maximum speed of 80 000 rpm.
