Dunkermotoren has developed hardware and software platforms for motion controllers. They comprise dMove and dPro designed for efficiency respectively for applications without host controllers.

The company located in the Germany’s Black Forest develops and produces integrated DC servomotors based on brushless DC motors for about 20 years. During this time, a variety of functions has been created, developed and optimized. “All these existing functions, now called ‘features’, were examined carefully in a first step. Already this step has made it clear how extensive a new motor base must be,” wrote Michael Bungert from Dunkermotoren in a white paper.
“Away from a rigid system that adds one function after another to a modular system where features can be combined when required. Our new platform was not only shown in the software, but also for the hardware. Flexibility came to the fore during development. This resulted in a motor control platform that, on the one hand, reflects all previous functions and, on the other hand, can react flexibly to new requirements,” he added.
The company’ engineers choose the latest generation of 32-bit micro-controllers to design the future-proof platform. This allows to use existing functions even more effectively and new ones, previously not possible functions, to be introduced. Electronic labels are only the beginning. In addition to the motor data, the labels also indicate the overall data of the whole drive, including the gearbox, encoder, and brake. In the future, the platform will provide functional safety. In order to meet different application requirements, there are two types of platforms:
The development of this motor control platform has now been largely completed. At last, the product launch can begin. Already available is the BG 95 dPro. A powerful motor with integrated electronics and a maximum output power of 2,6 kW, which offers the maximum functionality with the "dPro" characteristic. It can operate as a slave in the CANopen network, can be controlled directly via digital inputs without a communication interface or, can be freely programmed similar to a PLC (programmable logic controller).
The BG 95 dPro has already demonstrated that the concept of the new Motor Control Platform has proven itself in practice. Typical applications included intralogistics systems, electromechanical presses, mechanical test equipment, door drives, and special pumps.
