Dunker motors advantagesCompared to other motors, Dunker motors are very dynamic, fast and precise. The low wear and low maintenance is also very advantageous for high number of cycles. In addition, Dunker motors are particularly convincing due to their improved energy efficiency and better controllability. High-torque motors can simplify gearbox design and increase overall durability.Our specialists compared a 32mm diameter Dunker motor to a motor of the same diameter from another manufacturer. The motors have a similar continuous torque of approx. 45 mNm, but the rated power of 80 W at the competitor differs significantly from the 20 W specified at Dunkermotoren. This is due to the different rated speeds of 15000 vs. 3800 /min. However, to achieve the same torque, other motors require higher rpm, which would overload the gearboxes. High overload capacity of DC motorsWhen comparing different motor concepts, not only the power rating but also the high overload capability of the DC motor should be considered. In many applications with cyclic operating modes, it is not the continuous output power that is relevant, but the power that can be achieved in a short time. For example, when an automatic door encounters an obstacle, it needs to stop the door in time, which requires the motor to reach a high power in a short time. In addition, when the automatic door is about to open to the maximum width or before it is about to be completely closed, the door needs to be buffered, which also requires a high overload capacity of the motor. Dunkermotoren brushed and brushless DC motors can handle loads several times the rated torque. This is a feature not found in many other motor designs. |

Our microelectronic |
Microelectronic differenceThe reason why our microelectronic design is so complex is to provide more safety. We even use a microprocessor to constantly monitor the door in a unusual situation, it will intelligently change operating speed in time to ensure safety. |

Our wheels |
Low cost Nylon wheels |
Compared with nylon wheels, our wheels have the characteristics of high strength, wear resistance, corrosion resistance and aging resistance. Therefore our wheels can handle greater weight loads. Our wheels are made from a high molecular polymer material that performs well even in hot or humid conditions. |
