The PSD direct drives are mechatronic systems with integrated control, bus interface and absolute measuring system without battery. They are ideal for adjusting machine axes for format adjustments.

Thanks to the stepper motor with integrated control and bus communication, higher speeds are possible with low torques. This closes the gap to servo drives with a controller. The PSD direct drives impress with their significantly more compact design and low wiring effort, as no external controller is required - an economical solution for format adjusters.

Compact design
The direct drives from halstrup-walcher have a particularly compact design. Ideal for your slimline machine design

Maximum flexibility in configuration
Thanks to the variable alignment of the connector plugs and the optional rotatable attachment housing, the direct drives can be attached to the machine in any position. No angled connectors are required

Simple installation
The PSDs have a standardized NEMA flange for direct drives. The optional hollow shaft with torque support allows direct mounting to the spindle without a coupling.

100% repeat accuracy
Thanks to the monitoring with absolute encoder and the loop run / spindle compensation run, exact positioning is ensured despite spindle play. This ensures maximum repeat accuracy.

Larger travel range
With a positioning range of 977 ... 4026 revolutions, the PSD direct drives offer a large travel range. The absolute measuring system without battery ensures precise position feedback at all times.

Powerful start-up
Thanks to an adjustable starting torque/current, powerful starting is possible without any problems, even after standstill or in the event of contamination.

Dynamic adjustment
A high speed makes format adjustments more dynamic and thus shortens machine set-up times.

Safe even in the event of faults
The motor and control unit are electrically isolated, allowing the motor torque to be switched off without feedback.
