Drive controls, motors and controllers

Last updated: 5 October 2026 · Total: 23 products

This page is about how a power chair is commanded and what turns the wheels. Standard joystick modules such as the Curtiss-Wright R-net CJSM2 and Dynamic Controls LiNX REM400 combine driving, seat functions and a display. Mini and low-force joysticks like the mo-Vis Micro Joystick respond to very small movements of a finger, chin or lip. Other inputs include chin controls, head arrays, sip-and-puff tubes, single switches and eye control. Behind them sit the controller or power module, which meters current to the motors, and the motors themselves.

How to choose

  • Identify the electronics family on your chair first, since inputs are built for one system such as R-net or LiNX.
  • Choose the control site by the most reliable movement you have, whether hand, chin, head, breath or eyes.
  • Plan for programming by a qualified technician, because speed, acceleration and sensitivity are set in software.
  • Order motors by exact part number, as left and right units and gear ratios are not interchangeable.

Common questions

Can I drive a power wheelchair without using my hands?

Yes. Power chairs can be driven by chin joystick, head array, sip-and-puff, switches or eye tracking. An assessment with a specialist identifies which input gives the most reliable control.

What is a sip-and-puff wheelchair control?

It is a tube held near the mouth. Hard and soft puffs and sips of air are read as commands such as forward, reverse, left and right, so the chair can be driven with breath alone.
