Compared to spindle axes, linear direct drives are very dynamic, fast and precise. The low wear and low maintenance is also very advantageous for many applications with a high number of cycles. Compared to pneumatic axes, linear direct drives are particularly convincing due to their improved energy efficiency and better controllability.

The nominal power P(N) is the output power of the motor which can be generated permanently, calculated from nominal speed and nominal torque. The motors from Dunkermotoren are always measured according to EN60034 in thermally insulated condition. The measurement methods for the specification of motors are not standardized and sometimes differ significantly between the different suppliers. This makes it difficult to compare values even with comparable motor concepts and speeds.

DC motors can be operated above rated torque for a short time. The limits resulting from demagnetisation or control currents can be found in the specifications. Detailed information on the calculation of the effective torque in load cycles can be found in the Handbook for selection of motors from Dunkermotoren (page 75).

Brushless DC motors (abbreviation BLDC for brushless DC, also called EC motors) are designed like a three-phase synchronous machine with excitation by permanent magnets. The three-phase winding is controlled by a suitable circuit in such a way that it generates a rotating magnetic field which pulls the permanently excited rotor along with it. EC motors of Dunkermotoren are commutated and controlled by a mostly integrated electronic to which a DC direct voltage is applied.

Yes, electric cylinders of the CASM series are mechanically largely compatible with pneumatic cylinders.

Yes, the motor can also be operated with different voltages. For motors with integrated electronics, the permissible limits of the electronic components must be observed.

Motors from Dunkermotoren are usually designed for a standard industrial rated speed in the range of 3000 to 4000 rpm. If an application requires it, the speed can be easily adapted to the desired operating point by selecting a different winding.

Example: When using a GR motor with nominal 12 V at a supply voltage of 24 V, the no-load speed doubles and the entire motor characteristic curve shifts parallel accordingly. This results in a significantly increased continuous output power of the motor.

Generally, a servomotor is understood as a motor that has at least one control unit or can provide feedback on its rotational or linear position. "Servomotor" does not describe a specific motor type, but rather servo motors of different types. Permanently excited synchronous motors (BG series at Dunkermotoren), asynchronous motors and brushed DC motors (GR series at Dunkermotoren) are widely used as servo motors.

Further information on this issue can be found in the corresponding White Paper on the Dunkermotoren website (section "Knowledge").

In some cases, the North American market requires UL or CSA approved drives. With a few exceptions, we use UL listed materials. Ask us if your drive can be UL or CSA approved.

Many Dunkermotoren products have a CE mark. Typically, these include the brushless DC motors of the BG series with integrated control electronics, as well as brushed DC motors with corresponding interference suppression. Ask our sales department for details.

A smart motor is characterized by integrated control electronics and the ability to communicate via fieldbus or Ethernet interfaces. Dunkermotoren offers a wide range of intelligent motors, including the BG series dMove and dPro.

Actually, our motor control platform should be called a "carefree package". No matter how the motor is controlled, by bus or in stand-alone operation, the motor control platform guarantees that the motor reacts as desired. The motor control platform includes extensive servo functions to ensure that the motor regulates speed, position or current precisely in every application. Additionally, protection mechanisms are integrated into the platform to reliably protect the motor in unexpected operating conditions. The motor control platform has a modular design and is arbitrarily expandable.

Even if smart motors today can already handle complex tasks autonomously, control remains one of the most important functions of the motor. After all, a motor never works on its own. It interacts with its environment, for example a subsequent process step in a packaging system, an HMI in a medical device or the control of a driverless transport system. Whether by bus or in stand-alone operation, the control system must work reliably and quickly so that the motor works exactly as it should.

More than 20 years ago, Dunkermotoren recognized that customers benefit when as many components as possible are integrated in the motor housing, which would otherwise have to be configured together. These include brakes, encoders, power electronics, the communication interface and control electronics. All essential components are fully integrated in modern smart motors. Customers no longer have to design and combine individual components. They receive a compact complete drive that also reduces cabling to a minimum.

New sales colleagues at Dunkermotoren are very quickly confronted with a special phenomenon: Customers rarely want exactly the drive combinations that already exist. Their designers want to design devices, machines and systems as efficient as possible, i.e. not to undersize or oversize them, and to utilize the installation space as efficiently as possible. Every millimeter and every joules of kinetic energy counts. The more sophisticated and comprehensive the modular drive system, the more flexibly designers can select drives and design customized solutions.

In the Dunkermotoren online configurator, customers can select the perfect drive from a selection of the Dunkermotoren portfolio.

The technical specifications DIN VDE 0530-30-2 (VDE 0530-30-2):2019-02 harmonized the efficiency classes for electric motors with variable speed. Contrary to earlier efficiency classifications, it therefore includes not only induction motors, but also permanent magnet synchronous motors with a rated voltage >50 V and a rated power >120 W, regardless of the number of pole pairs.

The EC motors of the BG95 dPro series with integrated Motion Controller from Dunkermotoren already meet the demanding requirements for the highest energy efficiency classification for electric motors - the Ultra Premium Efficiency Class IE5. In the nominal power range of 859 W (BG 95x40 dPro 60 V) or 1126 W
(BG 95x80 dPro 60 V), the motors together with the integrated control electronics achieve an efficiency of well over 90%.

Pulse width modulation is a type of modulation in which a technical quantity (in this case the electrical voltage) changes between two values. The motor speed can be adjusted by changing the pulse widths.

GR series motors are basically suitable for operation at a modulated voltage, but only versions without noise suppression filter.

On the other hand, motors of the BG series are generally not suitable for a frequency-modulated supply voltage. However, some variants with integrated speed electronics have a setpoint input suitable for PWM voltages.

No difference!

Brushless DC motors (short: BLDC for brushless DC, also called EC motors) are designed like a three-phase synchronous machine with excitation by permanent magnets.

The three-phase winding is driven by a suitable circuit in such a way that it generates a rotating magnetic field which pulls the permanently excited rotor along with it.

EC motors of Dunkermotoren are commutated and controlled by a mostly integrated electronic to which a DC direct voltage is applied. BLDC motors are also similar to classic DC motors in their overload behaviour.

Yes, the motor can also be operated with different voltages. For motors with integrated electronics, the limits of the electronic components must be observed.

Dunkermotoren motors are usually designed for a standard industrial rated speed in the range of 3000 to 4000 rpm. If an application requires it, the speed can be easily adapted to the desired operating point by selecting a different winding.

Here Dunkermotoren is a pioneer and market leader. We launched the first EC motor with integrated control electronics and bus interface on the market in 2005. These are used to transmit information such as speed, temperature or current to the higher-level controller (condition monitoring).

In addition, Dunkermotoren enable a modular, decentralised and future-oriented control topology. The programmable motors offer numerous smart functions as standard, from I2t control to digital absolute encoders and gear backlash compensation.

For predictive maintenance, the data of all motors on Edge (on Premise) or in the cloud are additionally analyzed using KI algorithms in order to recognize patterns and derive predictions.
