Linear DD Motors — engineering schematic

Engineering schematic — not a product photograph. Dimensional drawings are issued with the quotation.

What it is

A linear direct-drive motor replaces the screw, coupling and nut with a coil assembly that rides along a magnet track. There is no mechanical transmission between the coil and the load, so there is no backlash, no screw whip and no wear surface in the drive train.

Design points

  • No screw, belt or rack in the drive train
  • No backlash and no screw critical-speed limit
  • Coil and magnet track supplied as a matched pair
  • Suited to high-acceleration and high-precision positioning

Typical fit

Laser processing, dispensing, inspection gantries, pick-and-place

Range parameters

Shared across the range. The exact figures for a linear design are fixed when we size it to your load case.

Range parameters. Individual models are sized to the application — request a datasheet for the exact figures.

Sizing note. Torque, speed and accuracy cannot be chosen independently. Send the load inertia and the duty cycle and we will run the sizing rather than guess at a part number.
