Inverter restarts on-the-fly

July 2007 Motion Control & Drives

Baumüller has developed the b maXX 1000, a highly efficient and easy-to-operate frequency inverter for vector control on standard motors. The unit is available in three frame sizes for power ranges from 0,2 to 11 kW.

The inverter has numerous built-in protection and overload functions. These include, for example, the standard addition of an EMC filter for compliance with the current EU standard (EN 55011A/second environment). As well as protecting the motor, the ability to detect phase losses on both the line and motor side ensures fault-free operation. Restart on-the-fly means that machines no longer have to coast to standstill in the event of transient power failures. PID control facilitates rapid response to noise interference and enables speeds to be kept constant. The comprehensive control and data management of the inverter provides a constant and precise overview of the current drive status.

Up to 15 different preset speeds can be configured for complex applications. Pulse width modulation can be set to between 1 and 15 kHz. This means that the frequency inverter operates with virtually zero noise. It can achieve a rotating field frequency of between 0,1 Hz and 400 Hz, meaning that even multipole machines can be operated at high speeds.
