Electric Wheelchairs - Controller Selection (Brushed Motor - PG Controller)

Following the previous Electric Wheelchair - Lithium Batteries and Choosing an Electric Wheelchair videos and articles. Another important component affecting the price, responsiveness, safety, and quality of an electric wheelchair is its controller.

1. Controller Brand and Quality

PG Controller: Curtiss-Wright's PG is one of the most commonly used brands for electric wheelchair controllers, but there are many counterfeit products on the market. Genuine PG controllers feature quick response, stable current, and durable design, while inferior controllers may affect user safety. See the distinguishing methods below.
Other Brands: Brands like Dynamic and Shark also offer reliable controllers. These brands typically meet international certification standards, ensuring safety and performance.

2. Controller Types

Brushed and Brushless Controllers: Brushed controllers generally react faster and are suitable for situations requiring higher power output; brushless controllers are lighter, require less maintenance, and are suitable for daily use. It is important to choose the appropriate motor type according to the user's needs.

3. Controller Functions

Responsiveness: When choosing a controller, check if its response is instant and stable. You can try it out in person to feel the flexibility and precision of the control.
Indicator Lights and Markings: The indicator lights on genuine controllers should be bright and clearly colored, and the markings should be clearly printed to avoid purchasing inferior products.

4. Certifications and Safety

Ensure that the chosen controller has relevant international certifications, such as CE certification, to guarantee its safety and reliability.

5. Usage Environment

Based on the user's daily environment (e.g., whether they frequently need to go uphill or navigate uneven terrain), choose a controller with appropriate power and capacity to ensure proper operation in all situations.
