Linear motor with top values for dynamics and energy efficiency

Oct 26.09.2024, XNUMX | Up to 50% lower power loss and up to 40% More nominal power: This is what the new L7 linear motors (pictured above) that Schaeffler presented at the AMB offer. Combined with particularly low operating costs, significantly shorter machining cycles can be achieved in the application. Greater machine precision is possible due to the lower heating of the motor and machine frame also given.

Schaeffler has been delivering for many years water-cooled iron-core linear motors of the L1 series with peak forces of up to 5171 N. With the new L7 types, Schaeffler is expanding its range of linear motors with peak forces of up to 24.300 N. Linear direct drives can therefore be used to a much greater extent in the main axes of machine tools and in handling systems.

L7 as a benchmark for efficiency and power density

The development engineers are concerned with optimizations copper windings, heat transfer and the cooling circuit, it was possible to achieve up to 50% lower power loss or up to 40% more nominal power of the linear motor with the same power loss compared to the current benchmark with the same drive power.

While motors with optimized peak power and power loss are offered on the market, the Linear motor L7 both strengths. It also offers excellent acceleration capabilities, while remaining significantly cooler. This means that engine operating costs can be drastically reduced and productivity significantly increased.

Measuring torque with sensors inside the transmission

In the case of permanent oscillating movement, which requires the highest accelerations and the Motor The L7 motor shows its strengths: The high power reserve enables a high degree of shape accuracy of the workpiece and the high acceleration capacity reduces cycle times. Thanks to very low power loss, little heat is transferred into the Machine bed initiated. This has a positive effect on the overall accuracy of the machine.

The right motor configuration for every task

The L7 linear motor family includes twelve motor sizes in four widths for the secondary section of 100, 150, 200 and 300 mm and in three lengths 350, 500 and 650 mm.

Alternatively, the high power reserve can be used downsizing to use. Because the moving mass is then reduced, this has a positive effect on the dynamic behavior. The dimensions of the motors allow existing axis designs to be easily converted into milling, turning and grinding machines as well as in laser processing.

Driven linear unit from Schaeffler with spindle drive as a horizontal axis for cobots

July 19.07.2020, XNUMX | For the multiple expansion of the area of application in the Robotic Schaeffler has a powered one Linear unit in the program. Users can install the driven linear module tailored to their design as a horizontal axis and thus answer questions about increasing the range.

The motor-driven linear axes from Schaeffler are available as individual Complete solutions available. Compact in design, it consists of the following components:

Tandem module Mdkuve
Adapter plate for the Cobot
Motor gear unit
assembled motor cables
Drag chain for cobot supply lines
Motor controller.

Connection of the linear unit

The linear unit contains the customer-specific connection to its control Profibus, Profinet or Ethercat Interfaces. The drive solution has variable connection options for the motor Transmission Unit. Optionally, the customer's drive technology can also be used.

The linear units are available in different lengths Ball Screw Mdkuve-KGT, toothed belt drive Mdkuve-3ZR or optionally with a linear motor as drive element.

Linear axis adapted to the load capacity and moment load

Schaeffler linear module In the tandem module as the basis of the linear axis, the guide carriage is guided on two parallel profile rails, type Kuve, as a four-row recirculating ball bearing unit. The compact design of the linear guide enables applications under high load and moment loads, as is sometimes the case with collaborative robotics. Using a triple Timing beltsdrive, the tandem modules offer the best possible reliability.

For applications with even higher requirements for load capacity and moment load, a guide carriage with the six-row Kuse..-XL recirculating ball bearing unit in X-life quality is suitable as a guide system for the linear axes.

The linear unit is available in different lengths up to multi-part axes for longer distances. The compact linear axis can therefore be easily integrated into a new or existing Automation integrable. Incidentally, Schaeffler offers assembly and installation services for this.

Technical characteristics of the linear axis

Tandem modules with ball screw spindle drive are available up to a maximum length of 5,9 m. The repeat accuracy of the linear units is 0,025 mm and the maximum speed is 1,7 m/s. With the toothed belt drive, multi-part linear units up to 18 m long can be realized. This enables speeds of up to 5 m/s with a precision of repeat accuracy of ±0,1 mm.

Servomotor | Electric motor with control electronics

In addition to the use of linear units in collaborative robots, the linear units are also suitable for use in the periphery of handling, assembly and factory automation.
