Whenever precision and controlled movements are required in drive technology, the stepper motor is the means of choice, as it can move to the desired position with millimeter precision. This is particularly important for applications in automation technology, at transfer stations and for format adjustments. The Cologne-based drive technology specialist igus has now developed a double-shaft stepper motor for its drylin linear axes for the first time. This motor is particularly characterized by its versatility and performance. The double-shaft stepper motor is a special type of stepper motor because it has two output shafts. "This design offers greater flexibility when connecting and driving mechanical components," explains Rene Erdmann, Head of the drylin E business unit at igus GmbH. "We can now drive two mechanical loads, such as two parallel linear axes, with just one motor." This not only saves space, but also reduces costs, as the motor is available at the same price as a single stepper motor and the user does not have to purchase a second coupling.

In contrast to conventional double-axis drives, where the motor is installed at the side and can cause space problems, the double-shaft stepper motor from igus sits between the axles and thus makes optimum use of the available installation space. Another advantage of the double-shaft stepper motor is the option of mounting a handwheel on the second shaft end. This means that the motor can also be turned by hand. This allows the user to manually adjust the zero point of a linear axis. In addition, a self-locking spindle axis can be adjusted manually by turning the handwheel, for example in the event of a power failure. This is particularly important in areas such as entrances or doors.
