Motor
Invacare’s GB motors are not only a key component of the TrueTrack technology, the
design is 75% efficient resulting in 17% more battery range than Invacare’s
4-pole motors. Battery range is an important feature for active users and users
requiring powered seating systems.
TrueTrack Technology
The patented TrueTrack technology features GB motors and motor controller. This
feature helps keep the power wheelchair on a true forward path – even on many
slopes, thresholds and uneven terrains. TrueTrack minimizes the need for veer
correction, diminishing fatigue for joystick and switch drivers.
TrueTrack Technology
is beneficial for the client for the following reasons:
•
As the power wheelchair holds a truer course, the driver needs to make fewer
course corrections. This makes driving more efficient by reducing the necessary
amount of movement. Reducing the required movement can increase overall
speed (i.e. the client may be able to move down a hallway faster, as less
compensatory movements are required), decrease fatigue, and promote
safety/independence while driving, because the chair is not pulled off course.
This is true for drivers using a proportional control as well as a digital or non-pro-
portional system.
•
This feature is critical for clients who fatigue easily, as less compensatory
movements are required.
•
This feature also is critical for clients who use a non-proportional or digital
access method (i.e. a head array with proximity switches or pneumatic sip-n-puff
controls). Driving with switches can be very tedious and inefficient. Making
frequent course corrections significantly increases the effort, time and energy
required. Fewer course corrections translates to a more efficient, safer driver.
