FAQ
Q: Do small volume DC brushless motors require sensors?
A: Sensor type (such as Hall sensor): provides accurate rotor position feedback, simple control, suitable for scenarios with frequent start stop.
Sensorless type: detects position through back electromotive force (BEMF) to reduce costs, but has slightly weaker low-speed performance.
Selection criteria: Need to balance cost, control complexity, and performance requirements..
Q: What specific size does small volume DC brushless motor refer to?
A: At present, our standard motor outer diameter is 20mm-130mm, but we can customize motor according to client needs.
Q: How is the vibration resistance effect?
A: Resistant to drilling vibration 30g5-200Hz.
Q: What are the applicable fields of the product?
A: Deep underground, deep ocean, deep space.
Q: How long is the warranty period?
A: One year or working downhole for 1000 hours
