Motor Flashhobby M3115 900KV

Order Flashhobby M3115 motor with 900KV torque - compact power for mini drones

The Flashhobby M3115 900KV engine is a small but powerful power unit. It is designed for miniature aircraft and models. This motor provides excellent traction in a compact size. You will get efficient performance with small propellers. It is an ideal choice for lightweight drones and indoor model aircraft.

Key advantages of the motor

• Compact size and light weight. Does not weigh down light aircraft.

• Low KV value for good torque. Provides traction with small propellers.

• Efficient design for stable performance. Prevents overheating in small enclosures.

• Universal application for drones and aircraft. Wide possibilities for modeling.

• Easy to install and connect. Even a novice enthusiast can handle it.

The essence of the work and design

This is a brushless external rotation motor. Its permanent magnet rotor rotates around the stator. The ESC controller supplies three-phase alternating current to the windings. The rotating magnetic field of the stator interacts with the field of the rotor. This creates smooth and consistent torque. The KV value of 900 ensures high traction at low speeds.

Technical characteristics and applications

The Flashhobby M3115 motor has a stator size of 31 mm by 15 mm. This is a small format for micro drones and light aircraft. Recommended supply voltage is 7.4V (2S LiPo). It can also run on 3S batteries with caution. The maximum power reaches 150 watts.

It is compatible with small propellers, typically 7-8 inches in diameter. This makes it a great choice for 250-300mm mini quadcopters. It is also suitable for small aircraft models such as trainers. To operate it, you will need a lightweight ESC with a current of about 20 Amps. This will ensure safe and efficient operation of the power plant.

This motor is often chosen for amateur and semi-professional assemblies. It performs well in flights in closed areas. It is also used on lightweight filming platforms with gumstick cameras. Installation is easy with standard mounting holes. Use screws of the appropriate small diameter.

It is important to choose the right propeller for the selected voltage. For 2S you can use larger diameter screws. For 3S - a smaller diameter so as not to overload the motor. Always check engine temperature after first flights. Balance the screws to minimize vibration and noise.

Regularly clean the motor from dust and check the shaft play. Timely maintenance will maintain its performance. Correct ESC setting also affects the smooth start.
