Direct drives
Direct drives are intelligent stepper motors for easy integration into machines
PSD direct drives are mechatronic systems with integrated control, bus interface and absolute measurement
system without battery. They are ideal for automatic
format changeover. Compared to servo drives, the direct drives PSD convince with significantly more compact designs and less wiring effort, as no external controller is required – an economical solution for format adjusters.
Advantages of the PSD 4xx direct drives
- Compact design: Ideal for your slim machine design
- Maximum flexibility: Variable orientation of the connection plugs and rotatable attachment housing saves angled plugs or gearboxes
- Easy mounting: Optional hollow shaft with torque support enables mounting without coupling
- Simple connection: All common bus systems are supported
- No reference run: Precise position feedback with absolute measuring system without battery
- Strong know-how: halstrup-walcher already has over 25 years of experience in the field of automatic format changeover
- Can be easily combined with other positioning system product families for format changeover
Design of the direct drives PSD
- 5 different data interfaces for bus communication with the machine control: CANopen, IO-Link, PROFINET, EtherCAT, EtherNet/IP (others on request)
- Performance data: from 1 Nm to 8 Nm nominal torque
- Mounting dimensions: Nema 17 and Nema 23 version with 5 or 8 mm solid shaft
- Output shafts for easy mounting on spindles: Optional hollow shafts with 8/14 mm
- 2 different IP protection classes: IP50 or IP65
- Various integrated software and protection functions
- Optional software modules for IO-Link connection
Flexibility through variable design of the direct drives
Already during the design of the PSD direct drives, we made sure that you can use the units flexibly in your machines. For example, both the plug connection and the optional attachment housing can be supplied ex works in different directions of rotation.
