2812 1115KV Brushless Motor Drone RC Airplane
The Motor 2812 1115KV is a brushless outrunner motor commonly used in drones, RC planes, and other hobbyist applications. Here’s a breakdown of its specifications:
Motor 2812 1115KV Details:
“2812” – Indicates the stator dimensions:
28 mm in diameter.
12 mm in height (stator stack thickness).
This medium-sized motor is suitable for small to mid-sized quadcopters or fixed-wing aircraft.
“1115KV” – The motor’s KV rating:
KV = 1115 (RPM per volt with no load).
This means the motor spins at 1115 RPM per volt applied (z.B., at 11.1V, it would theoretically spin at ~12,376 RPM unloaded).
A higher KV means higher RPM but lower torque, making it suitable for smaller propellers or high-speed applications.
Typical Applications:
Used in 5-7 inch propeller drones (depending on battery voltage).
Suitable for 3S (11.1V) or 4S (14.8V) LiPo batteries.
Often paired with 20- 30A ESCs (Electronic Speed Controllers).
Lower KV (z.B., 800-1200KV) → Better for larger props & Effizienz.
Higher KV (z.B., 2000+ KV) → Better for small, fast-spinning props (z.B., racing drones).
