Hans Direct Drive Server Motors

Manufactured by: Hans
Sold and Serviced by Motion Technologies Pty Ltd. Ph +61 2 9524 4782.

By adopting direct drive technology, DDR motor gets rid of retarding mechanism and has the following advantages.

  • High dynamic performance and high reliability
  • Direct extension of the force no mechanical transmission
  • Maintenance free drive
  • Simplified mechanical design
  • High dynamic response and high drive control
  • High positioningaccuracy
  • Simple installation and removal

Kollmorgen Cartridge DDR (Direct Drive Rotary)

Manufactured by: Kollmorgen
Sold and Serviced by Motion Technologies Pty Ltd. Ph +61 2 9524 4782.

The Cartridge DDR motor is the newest addition to the Kollmorgen line of DDR products. The Cartridge DDR motor does not have bearings and it mounts to a machine using the machine’s existing bearings to support the motor’s rotor. The frame of the Cartridge DDR motor mounts to a pilot and bolt circle on the machine frame much like a conventional motor. The rotor engages to the load using an innovative compression coupling, which effectively makes the motor’s rotor and the load one piece, eliminating any compliance between the motor and the load.

  • Torque to 1090Nm
  • Speed to 2500rpm

Kollmorgen Housed DDR Motor Selection Guide

Manufactured by: Kollmorgen
Sold and Serviced by Motion Technologies Pty Ltd. Ph +61 2 9524 4782.

Our Housed Direct Drive Rotary (DDR) motor series offer a high performance, zero maintenance servo solution. They achieve very high torque density through the combination of large diameter, short length, and a high number of magnetic poles.
By pairing the Housed DDR motor series with our wide range of plug-andplay Ethernet-based AKD™ servo drives, you can optimize performance and increase the machine’s overall effectiveness. The DDR motor can be used as a flexible indexer, providing programmable, rapid, indexing far exceeding the throughput of conventional mechanical or variable reluctance technology indexers. It can also be used for replacing mechanical transmissions such as gearboxes, timing belts, and rack and pinion reducers.

  • Torque range from 5.3Nm to 339Nm continous
  • Speeds from 500 to 120rpm

Oemer Direct Drive Motors

Manufactured by: Oemer Motor
Sold and Serviced by Motion Technologies Pty Ltd. Ph +61 2 9524 4782.

The permanent magnet synchronous motors of the LTS series have been developed and made to specifically meet the requirements of modern motorization where the “load” is driven directly by the motor without any additional mechanical equipment such as reducers, belts and pulley, or countershafts.
The concept is extremely simple – to apply the torque generated by the electric motor directly where it is required; on the shaft of the machine.

  • Low speed synchronouse AC, 16, 24 or 36 poles
  • Power up to 496Kw
  • Output torque from 120 to 14,000Nm
  • Frame size 132 to 355
  • Optional spherical thrust roller bearing
  • Water cooled
