maxon motor develops new controller for driving brushless DC motors without Hall sensors

Maxon Motor UK : 14 September, 2007  (New Product)
maxon motor has introduced a new controller for driving brushless DC motors without Hall sensors - the DECS 50/5 (Digital EC Controller Sensorless).
Typical sensorless drives such as pumps and fan applications can now easily be created thanks to modern technology and expert integrated controlling algorithms.

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 analogue set value. The 1-Q amplifier can be operated at up to a maximum speed of 80 000 rpm.

As well as being a top performer, attractively priced and small, the new amplifier's other key feature is that it can be easily adapted to specific requirements. The free choice of starting sequence is a major benefit, as it allows the attached motor to start up easily, even when the motor data or load ratios are unfavourable. maxon's own in-house developed speed controller, the DECS 50/5 also provides control inputs for selecting motor direction, enable and braking. The protective functions have all been fully implemented. An operating status display (LED) and speed monitor output complete the convenient control features.

Plug-in screw terminals and a Flexprint connector for maxon flat motors are available for the connection. The module can easily be used immediately in all applications because of its robust control design.
