Brushed or brushless: where the money goes

Two motors that look identical on a spec sheet differ in what wears out first, what it costs to fix, and how the chair sounds going up a slope.

The motor is the part of a power chair that fails first after the battery. The specification sheet usually gives you watts and a voltage. It rarely tells you which kind of motor it is — and that is the number that predicts your service costs.

The mechanical difference, without the engineering lecture

A brushed motor transfers current to its spinning coil through carbon brushes that physically rub against a commutator. Those brushes wear down. A brushless motor switches current electronically and has no rubbing contact.

Consequences that matter commercially:

Brushed — cheaper to build, simple to repair, wears out. Eventually the brushes need replacing, and on a sealed unit that often means replacing the motor.
Brushless — more expensive up front, quieter, and no brush to wear. The electronics become the failure point instead.

Which of ours is which

Brushed: JYW001 (250 W × 2), JYW002 (180 W × 2), JYW5903 (250 W × 2)
Brushless: JYW5919 (200 W × 2), T100 (150 W × 2)

Note the wattage. T100 is the flagship and has the lowest motor rating in the range — 150 W per side. That is not a cost cut. On a light carbon chair, less motor is often enough, and a smaller brushless motor draws less from the pack, which is how it reaches its range figure on a 12 Ah battery.

How to sell it honestly

Do not lead with “brushless is better”. Lead with duty cycle:

Occasional use, short trips, tight budget → brushed is the right answer and saying so builds trust.
Daily use, hills, heavy user, or a rental fleet where downtime costs money → brushless pays for itself.

Ask your supplier one question before you commit a container: “Are the brushes replaceable as a service part, or is the motor sealed?” If they cannot answer, they have never serviced one.

The noise point is not cosmetic

Brushed motors whine. In a care home or a hospital corridor, that whine is the difference between a chair that is accepted and one that residents complain about. It is also the first thing a buyer notices in a demo — before they look at the specification at all.
