Electric Wheelchair Controllers - Why are PG Controllers so highly recommended?
Most Recommended Power Wheelchair Controller - Curtiss Wright's PG Controller
PG (PG Drive Technology) power wheelchair controllers are a business unit of the US-listed Curtiss-Wright Corporation (Ticker: CW).
Curtiss-Wright Corporation, founded in 1929, is a global innovative company focused on providing highly engineered, critical function products for the commercial, industrial, defense, and energy markets. Headquartered in North Carolina, it has multiple manufacturing facilities and operational bases in the US and other regions.
Key Products and Services
Curtiss-Wright manufactures many advanced machine components and holds a leading position in:
- Actuators
- Controllers
- Aircraft Control Systems
- Valves
- Military Machinery
In the power wheelchair industry, Curtiss Wright's PG controllers hold a leading position and are widely recommended by various power wheelchair specialty stores.
The advantages of PG controllers over cheaper alternatives are:
1. Fast response, high immediacy, and capability to handle high currents
2. Sufficient torque at low speeds and low currents on inclines, preventing the wheelchair from rolling back on slopes
3. More durable, not easily damaged even upon impact
4. Flexible adjustment: Users can adjust parameters such as acceleration, deceleration, and maximum/minimum speed according to personal needs to achieve optimal usage.
International brands like Sunrise Quickie, Joy Rider, or Pride's latest power wheelchairs all use PG's nVR2 controllers. Thanks to their patented technology, they are more flexible, durable, and user-friendly, providing a very smooth experience.
In Hong Kong, we have more slopes, and rolling back on a slope can pose safety risks. Even with the same battery and motor, the performance can vary significantly with different controllers. One unique feature of the PG controller is its ability to deliver high torque to the motor even at low speeds, making ascending and descending slopes effortless.
Sanctions Situation and Impact in China
In recent years, due to economic conditions and the impact of US-China sanctions, there has been a shortage of electronic control chips in the market, coupled with rising inflation costs.
This makes it difficult for Chinese manufacturers to procure PG controllers. A single PG controller costs around 3,000 RMB or more, and supplies are often unavailable. As a result, the power wheelchair market has seen many entry-level or knock-off cheap products (examples can be seen here) used for arbitrage.
Our company has directly contacted the PG controller manufacturer to use genuine PG controllers, hoping users can receive the best and safest quality.
