The motor operates in a wide voltage range from 15 to 30 Volts. It produces an impressive 2100 watts of power. Your drone will have a reserve of thrust for difficult tasks. Choose advanced Russian technologies for critical missions. Order BKM 220 “Sarma” right now in our store.

• Completely domestic development and production from Russian components.

• High power of 2100 Watts for lifting heavy loads and professional equipment.

• Wide power range 15-30V (4-8S) for flexibility in battery selection.

• The optimal KV 220 for working with large propellers.

• Robust design with a massive 8mm shaft for high torque transmission.

Operating principle and design features

The BKM 220 engine is a brushless synchronous machine of the Outrunner type. It works on the principle of interaction of a rotating magnetic field. The current from the battery is supplied to the stator windings through the speed controller. The electronics create a magnetic field that rotates a rotor with powerful magnets. The external rotor provides high torque in a compact size.

Russian engineers have created an engine with improved performance. It has less weight and higher efficiency compared to imported analogues. The motor was successfully tested on the Burya-10 unmanned aerial vehicle. This device with Sarma engines delivered medicines to the hard-to-reach village of Khasurta. The drone covered a distance of more than 200 kilometers. This confirms the highest reliability and efficiency of the power plant.

Specifications and Compatibility

Study the exact parameters of the BKM 220 Sarma engine. The operating voltage is from 15 to 30 Volts. This corresponds to 4S, 5S, 6S, 7S and 8S LiPo batteries. Current consumption in operating mode reaches 70 Amperes. Rated electrical power is 2100 watts.

The KV motor speed constant is 220. This is the optimal value for large, large diameter propellers. The motor weighs 450 grams. Overall dimensions: 79.2 mm in diameter and 45.5 mm in height. The diameter of the output shaft is 8 millimeters. This ensures reliable transmission of force to heavy screws.

The motor is compatible with powerful speed controllers. We recommend an ESC with a current of at least 80-100 Amps. The regulator must support the selected voltage 4-8S. Propellers are selected for a specific task and load capacity.

Areas of application and operation

The BKM 220 engine is ideal for heavy unmanned platforms. It is used in cargo drones to deliver packages weighing up to 11 kg. Used in agricultural drones for spraying fertilizers. Suitable for geodetic complexes with professional equipment. It is the choice for monitoring pipelines and power lines.

For correct operation, a high-quality speed controller is required. Use large diameter propellers with a small pitch. Use high quality batteries with a high C-rating. Ensure reliable cooling of the entire power plant.

Domestic production guarantees independence from imports. The U-UPPO enterprise is part of the KRET concern of the Rostec State Corporation. It is planned to produce more than a million products per year. You get a reliable product that has undergone real flight tests.
