A25 is designed for 30-50 V DC propulsion systems, with a rated input current of 45 A and a motor mass of 1200 ± 10 g. Designed for durability, with a service life of up to 5000 hours.
Quality that matters every time the motor runs. Our brushless motors prioritise long service life and consistent performance, helping reduce replacement frequency in drones and industrial equipment.
Actual service life depends on load, temperature, installation and maintenance. Confirm the applicable model and operating conditions when selecting a motor.
A25 accepts 30-50 V DC. Evaluate rated current, propeller and required thrust at a common operating point. The source test conditions and point-by-point results below help compare power requirements. Motor mass, mounting geometry and cooling also affect system integration.
Final configuration depends on operating conditions and the agreed specification.
Propulsion performance depends on the motor, ESC, propeller and power supply working together. Changing the propeller changes current, thrust and temperature rise. Start with the test table for the intended propeller and supply, then validate the operating point in the complete system.
Define take-off mass, rotor count, hover thrust, peak mission load and supply range before selecting a motor. Allow current and thermal headroom and check the shaft, mounting pattern, propeller hub and wiring. Do not treat maximum tabulated thrust as sustained hover capability.
Isolate power and confirm safe discharge before wiring. Check rotation without a propeller; to reverse it, isolate power again and exchange any two phase leads. With the propeller fitted, increase load gradually in a controlled test area and record voltage, current, speed, thrust, vibration and temperature; inspect fasteners.
Stop for abnormal noise, vibration, overheating or binding. Never carry the motor by its leads or shaft; inspect insulation and bearings after a drop. The documentation requires bearing temperature below 100 °C in the worst case. Service life up to 5000 hours remains dependent on load, temperature, installation and maintenance.
Geometry follows the source. Verify the actual model and approved drawing before installation.
