Electrical linear actuator now available from Nanotec in a new 56 mm size

Landsham, May 5, 2011 – With the L5918 model (56 mm installed size/Nema 23), Nanotec Electronic GmbH & Co. KG has extended the upper range of its line of electrical linear drives. In addition to the low-friction threaded bushing made of high-performance thermoplastic material, the model is distinguished by its compatibility with Plug & Drive motors such as the PD4-N. This makes the simplified designing of efficient, integrated linear systems possible.

Especially with regard to larger sizes, a constructor must decide whether to use a hydraulic, pneumatic or electrical drive. Flexible motor design and low service requirements speak in favor of an electrical drive, as it does not need any auxiliary units. Nanotec developed the L5918 linear actuator on the basis of its high-torque stepper motors, making it compatible with all of the manufacturer's standard stepper motors. At up to 1000 N thrust, the force coupling is carried out directly in the hollow shaft motor. Even the strongest forces can be precisely regulated, with low energy requirements. With regard to the L5918 model, the step resolution goes up to 0.01 mm in full step. In microstep and with an encoder, resolutions of up to 0.001 mm can be attained.

A 200 mm long lead screw is available for the L5918 linear actuator. The spindle pitch is 2 mm. Generally, the lead screws are clamped or attached to the part to be actuated. If this is not possible or an unengaged lead screw end has to actuate the load, the L5918 – with an antirotationally-safeguarded pushrod – is available as a ready-to-install linear positioning drive, e.g. for highly dynamic and rigid machine designs or multimotor operation.

The L5918 is ClosedLoop-capable and can be operated as a high-pole servomotor, together with an encoder (available as a standard option) and an appropriate controller with field-oriented control. As a customer-specific variant, it is also possible to combine the L5918 with an integrated controller, such as in the PD4-N Plug & Drive motor.

With respect to a standard design construction – with linear axis, coupling, motor, encoder and controller, the only thing that is also necessary is a very compact unit for linear positioning. This compactness is a major advantage, particularly where manual format adjustment is to be automated in existing machinery.

As with all hybrid linear actuators from Nanotec, threaded bushings made of polyetheretherketone high-performance plastic are also used for the L5918 motor. They are also extremely wear-resistant, even when subjected to high thermal and mechanical loading. Consequently, the thermoplastic nuts from Nanotec offer significantly better sliding properties compared to conventional threaded bushings made of bronze, because there is much less friction and they are nearly twice as efficient. The motor's life cycle is higher and the maintenance effort is less, thanks to the self-lubricating nuts.

Based in Landsham near Munich, Nanotec GmbH & Co. KG is one of the leading manufacturers of motors and controllers for high quality drive solutions. Since 1991, the company offers a broad product range distinguished by well thought-out design and strict quality control. Certification to the latest ISO 9001:2008 standard by the TÜV Management Service is proof of this quality. Only rarely can a standard motor or power electronics be used “out-of-the-box". This is why Nanotec builds customer-specific versions in relatively small numbers and works with its engineers to develop optimum and individual solutions for its customers. In-house final assembly at the company headquarters in Landsham, near Munich, and broad-based warehousing allow Nanotec to quickly and flexibly react to customer demands.
