New stepper motor provides cost-effective dual drive

Where precision and controlled movements are required in drive technology, the stepper motor is the tool of choice with high precision particularly important for applications in automation technology, at transfer stations and format changeovers.

The twin-shaft stepper motor has two output shafts. This design offers greater flexibility in the connection and drive of mechanical components, explains Rob Dumayne, dry-tech director at igus UK. With one motor, we can now drive two mechanical loads, such as two linear axes running in parallel. This configuration not only saves space but also cuts costs the motor is the same price as a single-stepper motor.

One motor, three functions

In contrast to conventional double-axis drives, where the motor is installed on the side and can cause spatial problems, the twin-shaft stepper motor sits between the shafts and so makes use of the available space. Another advantage of this stepper motor is the possibility of mounting a handwheel at the second end of the shaft, meaning that the motor can be turned by hand if there is a power outage. It also allows the user to manually adjust the zero point of a linear axis. In addition, in the event of a power failure, a self-locking spindle axis can be adjusted manually by turning the handwheel, which is particularly important in areas such as entrances or doors.

In addition to stepper motors, igus offers EC/BLDC and DC motors in its online shop starting from just 33. The matching igus motor power amplifiers, called dryve, are available from less than 60. High performance controllers with BUS connection and integrated web server are also available.
