In electric valve systems, low-voltage operation (such as 3V or 5V) is often required for compact and energy-efficient designs. However, a common challenge arises: insufficient torque to reliably open or close the valve.
This issue becomes more critical in space-constrained applications, where increasing motor size is not always feasible. Therefore, selecting a suitable micro motor under low-voltage conditions is essential.
From an engineering perspective, low-voltage operation can result in:
Lower input voltage limits current, making it difficult to overcome initial load resistance.
High-speed motors operating at low voltage may enter unstable performance zones.
Compact valve systems restrict motor dimensions, limiting torque output options.
