Dynamic linear motors provide flexible, modular design

Beckhoff's new generation of highperformance, modular linear motors has been developed in cooperation with its subsidiary Fertig Motors, and the company’s new AL8000 product family is based on a modular system design consisting of linear motors and magnetic plates. Machine builders can choose between three widths: 50 mm, 80 mm and 130 mm. In addition, each available width offers a range of different linear motor types providing options in overall length, the type of winding and the cooling type. The standard product portfolio offers a total of 28 different linear motor types for linear axes to suit a variety of application requirements. Depending on the size of the linear motor, peak forces of 120N to 6,750N are possible with maximum speeds of up to 12 m/s.

In keeping with Beckhoff’s established AM8000 rotary servomotors, the AL8000 family of linear motors has been developed and is manufactured in Germany to assure a consistently high level of production quality. 

Modular coil design

In keeping with its modular system principle, the linear motor coil comprises individual, identical segments, a method of construction which Beckhoff says favours efficient production. Depending on which version of a linear motor is ordered, the production process can be quickly and easily adapted accordingly, thus reducing overall manufacturing costs. The linear motors feature a symmetrical structure with uniform intervals between the mounting holes of the complete AL8000 series. Beckhoff states that this makes it easier for machine manufacturers to construct the machine slide, and also ensures consistent force and temperature distribution within the motor without critical hot spots.
