FAQs

Please read our FAQs page to find out more.

What is the difference between continuous and peak power?

Continuous power is the level the motor can safely handle over long periods. Peak power is the short-term maximum during acceleration or climb. Exceeding continuous ratings can cause overheating.

What happens if the motor exceeds its maximum temperature?

The motor temperature should normally be monitored by the ESC through the built-in motor temperature sensor. If thermal protection is disabled or not supported, excessive heat can cause partial demagnetization of the magnets, leading to permanent loss of performance or complete motor failure.

How to prevent overheating?

Ensure proper cooling by maintaining sufficient airflow or liquid circulation around the motor. Overheating often indicates that the motor is overloaded or operating outside its efficiency range. Always match the motor with a suitable propeller, gearbox, or load to keep current within the rated limits. Monitor temperature through telemetry and avoid running at peak power for extended periods

What does KV mean?

KV indicates how many revolutions per minute (RPM) the motor produces per volt.

What maintenance does a BLDC motor require?

Brushless motors are mostly maintenance-free. Periodically clean the motor using dry compressed air to remove dust and debris. Avoid using liquids or solvents, and make sure no moisture enters the housing. Check bearings occasionally for smooth rotation.
