Dunkermotoren is the world market leader for BLDC motors with integrated electronics. For decades, the company has been known for its robust and intelligent electric drive solutions. True to this year's theme "Global Farming - Local Responsibility" at Agritechnica 2019 in Hanover, Dunkermotoren is presenting efficient drive solutions for resource-saving agricultural applications.
Electric BLDC motors are increasingly being used instead of hydraulic drives in agricultural plant and machinery. This development requires the use of smart electric motors with CANopen or Ethernet communication interfaces. Developments towards increasing networking, cloud-based platforms and decentralisation of computing power open up completely new possibilities for manufacturers of agricultural technology. With the data provided by the engine, an analysis and use are possible, which in logical consequence can reach up to autonomously executed tasks.
The BLDC motors with integrated electronics are therefore an essential part of SMART FARMING philosophy and enable resource-saving use in agriculture. The heart of an intelligent brushless DC motor is the electronics used. The controller is completely integrated into the motor, thus relieving or simplifying the customer's electronics. In addition to controlling the motor, the electronics can also perform tasks such as data monitoring. This enables precise evaluation of the travel paths. In addition, previously defined events can be monitored by the engine electronics, such as an increase in friction or wear. In this way, deviations are detected immediately, and preventative measures can be taken to avoid downtimes. Actual values in the field can thus be analyzed easily and conveniently. Due to the high power density, comparatively small electric motors with a high degree of efficiency can be used, whose energy requirement is correspondingly low. This not only reduces fuel consumption, but also relieves the strain on the on-board power supply, which is in many cases exhausted.
Dunkermotoren developed the Motor Control Platform based on the modular approach, which enables flexible configuration of the electronics according to functional requirements such as speed, positioning and current control operation. Control via CANopen or industrial Ethernet interfaces is possible.
The integration of the electronics in the motor housing protects the electronics from environmental influences. Due to the robust design with a solid steel or aluminium housing and optional paint or coating, the entire drive train can achieve a protection class up to IP69K. The integration of the electronics results in less cabling and enables simple plug & play commissioning.
With an output power of up to 3,900 W at a possible 12 VDC to 325 VDC supply voltage, Dunkermotoren motors cover a wide range of agricultural applications.
In addition to brushed and brushless DC motors, the product portfolio also includes linear drives, gears, encoders and brakes, with which countless combination options can be realized within the modular system. Whether seed drill, maize chopper, fertilizer spreader, stable or milking robot - the use of Dunkermotoren enables flexible, robust and trend-setting solutions.
