Integrated Compact Drive

Project: January 1998 – March 2001 (39 months)

Description

Collaboration in the planning and creating of an electronic control system for a compact drive with EC motor technology in the power range up to 100 watts. Power and positioning electronics as well as a spur gear with needle bearing are attached to the motor. Only one supply cable and one fieldbus cable are required for the control. Communication takes place via the CAN bus according to the CANopen device profile CiA DSP-402 (Device Profile for Drives and Motion Control).

Integrated Linear Drive

Project: May 1996 – December 1997 (20 months)

Description

Collaboration in the development of an electronic control system for a linear drive with an adjustable motor. The drive is used for linear movements in machines / systems and is especially suitable for industrial applications with heavy loads (up to 20 KN). A sturdy aluminum housing integrates motor, gearbox and control electronics. Operation with all options (speed, positioning, soft start / stop, time-dependent functions etc.) can be programmed directly at the drive itself or through a system interface (for example CAN / CANopen, Interbus, Profibus).

Filter Fan Unit

Project: October 1995 – April 1996 (7 months)

Description

Collaboration in the development of an electronic control system for the operation of fans (EC technology) used in clean room areas and building air conditioning. Fan controllers are connected via RS-485 bus with a hierarchical, multi-stage topology. At most, 31 x 8 x 31 devices can be networked; the largest installation included around 2,500 fan units (chip fabrication). Operation and visualization, installation and maintenance were conducted via a RS-232/RS-485 gateway on an industrial PC. The cycle time on the PC takes around 5 minutes with 7,688 fan units.
