Electric Wheelchair Motor

The first commercially produced electric wheelchairs were merely heavy-duty manual folding-frame wheelchairs that were powered by lead-acid batteries, motors, drive belts, and pulleys. Those systems, known as conventional power wheelchairs, were very simplistic. They required the use of ajoystick to control the wheelchairs movement, and programmability did not exist. The seating system typically consisted of a sling seat and back upholstery, which significantly limited postural support for the individual.

The advent of the power base, which sits beneath the seat and contains the motor and batteries, allowed for significant mechanical advancements in electric wheelchairs. The power base separated the electric wheelchair into two components: the base, which provided the mobility, and the seating system, which provided the postural support. At the same time that a shift from a conventional power wheelchair to a power-base wheelchair was taking place, significant advancements were occurring in electronic systems. Some of those mechanical and electrical advancements included the ability to add power tilt and recline systems and programmable performance settings (e.g., forward speed, turning speed, and acceleration). Joysticks, the most basic and common devices used to control electric wheelchairs, came to resemble those used with computer game consoles. Advancements in control systems allowed individuals to control a wheelchair by using any voluntary movement. For example, some electric wheelchairs can be controlled by using head movement, breath actuation, tongue movement, or lower extremity control.

Two types of drive mechanisms are used on electric wheelchairs: indirect drive and direct drive systems. Indirect drive systems (pulleys and drive belts) are used on conventional electric wheelchairs, whereas direct drive systems (gear boxes) are used on power-base wheelchairs. The vast majority of contemporary electric wheelchairs use a power base with a direct drive system. Typically, two 12-volt batteries in series (24-volts total) are needed to power an electric wheelchair. Wet cell batteries, gel batteries, or absorbent glass mat (AGM) batteries may be used in electric wheelchairs. Electric wheelchair batteries typically are rechargeable.

Electric wheelchairs also can be classified on the basis of the location of the drive wheels. There are three types of electric wheelchairs: front-wheel drive, mid- or centre-wheel drive, and rear-wheel drive. Traditionally, rear-wheel drive electric wheelchairs were preferred because of their similarity to manual wheelchairs in design and maneuverability. However, centre-wheel drive wheelchairs have gained popularity because they provide increased maneuverability.

Push-rim-activated power-assisted wheelchairs (PAPAWs) incorporate features of both manual and electric wheelchairs. A PAPAW typically consists of an ultralight manual wheelchair with an external power source (batteries and motors). It complements rather than replaces an individual’s ability to manually propel the wheelchair. The push-rim contains sensors that detect the direction and magnitude of force applied to it by the individual. The motors are then activated and assist in the propulsion of the wheelchair.

Manual wheelchairs motors aren’t the easiest aid to use for someone with limited upper body strength. Wheelchair owners must either exert their own arm strength or rely on someone else to push the chair for them

But a motorized wheelchair requires virtually no physical effort at all. Powered by battery-operated motors, electric mobility wheelchairs are self-propelling and enable their users to get around much more independently and more easily.

Different Mobility Needs Require Different Motors

The motor is usually found beneath the power chair seat and connects to thejoystick controller. The controller, in turn, proportionally outputs battery power directly to the motors. Individual differences in function, design and how an owner intends to use the equipment, will typically dictate the kind of motor and the amount of horse power a particular type of power chair will need.

Standard-Sized Power Chairs usually have dual, in-Iine motors and require moderate amounts of horse power. They are best suited for routine indoor use by riders of average height who weigh up to 300 pounds.
