DUNKERMOTOREN have developed a brushless DC motor that incorporates not only the power supply, but also the control and positioning electronics, PLC functions, BUS links along with various encoder and brake options. The 550 watt BG 75 DMC brushless motor (Direct Mains Connection) succeeds in eliminating the need for an external power supply whilst also accommodating all the functionality into the motor housing. Around 20 years ago the control components would have filled a small cabinet, now they are completely integrated in the motor housing and depending on the application, a control cabinet is completely unnecessary.
To enable maximum end-user benefit the reactive power compensation has been incorporated and where required, the motor can be adapted to feed energy back into the grid, even during braking. In future, a complex external power factor correction method and in some cases, a braking resistor will be dispensed with. Thanks to the integral design of the motor, installation and commissioning is easy and renders the need for wiring in the control cabinet as unnecessary. The term, single-cable solution usually refers to the connection between the motor and the controller. With the BG 75 DMC it includes the complete drive up to the 230 VAC supply. This innovative, integral drive unit provides an ideal solution for motion control in modular or 'single motor' applications and machines.
