EL.MOTION - the drive units for Industry 4.0
The machinery and plant engineering industry is currently facing very specific technical challenges: the need for modernization, simplification and standardization. At the same time, extreme flexibility and agility, i.e. rapid implementation and a high degree of adaptability to constantly changing requirements, are required. These conflicting demands, coupled with the tendency for engineering departments to be overloaded, often lead to conflicting objectives during implementation.
As the prime mover of every production process, drive technology plays a central role in reconciling the technical conditions with the daily reality of production. It is therefore high time to find answers and solutions for a fast, simple and safe adaptation of drive units. Erhardt+Leimer meets this challenge with its state-of-the-art EL.MOTION drive concept and sets new standards for Industry 4.0.
Products & services
Rotary drive units AD 11, AD 12 and AD 14
The AD 11, AD 12 and AD 14 rotary drive units are synchronous machines with a high power density. The motors achieve a torque of 1 - 4 Nm at speeds between 230 and 1000 rpm in a compact package. This enables gearless operation in many applications. Thanks to a special protection provided by a double-row angular contact ball bearing, high axial loads are also possible without any problems. This means that the drive units can be connected directly to a machine without a coupling and can therefore be easily integrated into existing production lines.
Linear drive units AG 90, AG 91, AG 93 and AG 96
The linear drive units AG 90, AG 91, AG 93 and AG 96 are synchronous motors with high control accuracy and control dynamics. The nominal actuating forces of the motors range from 250 to 5500N at feed rates of up to 60 mm/s. The linear drive units are particularly suitable for long-term applications and are used, for example, on running webs for web control at unwinding and rewinding stations.
EL.MOTION - the drive units for Industry 4.0
The EL.MOTION BLDC drive units. The EL.MOTION drive units from Erhardt+Leimer comprises a wide range of gearless synchronous drives. The product portfolio includes linear and rotary drive units. The groundbreaking innovation of EL.MOTION lies in the fact that the previous BLDC machines in this performance class can now be replaced by synchronous machines. This makes it possible to achieve the high dynamics and control accuracy. The motors can be controlled via web-based management using any browser. LINEAR DRIVE UNITS The linear drive units AG 90, AG 91, AG 93 and AG 96 are synchronous motors with high control accuracy and control dynamics. The nominal actuating forces of the motors range from 250 to 5500 N at feed rates of up to 60 mm/s. ROTARY DRIVE UNITS The AD 11, AD 12 and AD 14 rotary drive units are synchronous machines with high power density. The motors achieve a torque of 1 - 4 Nm at speeds between 1000 and 230 rpm in a compact package. This allows gearless operation in many applications. High axial loads are also easily accommodated thanks to the protection provided by a double-row angular contact ball bearing. STO – safe torque off The STO (safe torque off) safety function according to EN 61800-5-2 is an optional addition to Erhardt+Leimer drive units. It is an in-drive safety function that shuts down the motor torque by interrupting the control pulses. EL.MOTION with EL.NET for a connected production As with many other products, a growing number of EL.MOTION drive units can use the EL.NET network technology from Erhardt+Leimer. EL.NET makes it possible to display and address many components within a production process in one standardized network. This means that data from running webs can be easily connected across devices and can be monitored and analyzed in real time. Increased productivity, consistent production quality, and new automation options are just a few of the many benefits EL.NET has to offer.
