M13 EEE

Product overview

The M13 EEE is a propulsion component for UAVs, not a complete aircraft or airframe kit. MAD designed it for professional multirotors that carry heavy loads on each axis and optimized it for 7–9 kg single-axis payloads with 36-inch carbon fiber propellers. Peak thrust reaches up to 20.5 kg per axis. The motor weighs 615g, so it suits builders who want a high thrust-to-weight ratio and more power output without extra motor weight. It supports 12S voltage systems, is listed with a 90KV option, and is intended for high-efficiency operation at 12S in demanding aerial applications.

The motor measures D:116 × 35 mm and has 21 pole pairs, an anticorrosive stator and varnished wire rated to 220°C. It has two 6802ZZ bearings and independent centrifugal heat dissipation. Rotor balance is ≤10 mg and motor balance is ≤20 mg, and the motor is rated for a 500 V disruptive test. A separate motor balance entry of 180°C also appears next to the motor size. The motor mounts to the airframe through an M5×4 pattern on a D:50 circle, and the shaft diameter is IN: 15 mm. Propellers attach through either an M3×4 pattern on D:20 or an M4×4 pattern on D:23. The 150 mm leads are extended enameled wires.

Some points matter for integration. The degree of protection is described only as rain protection, so plan for weather exposure on that basis. The motor is specified for 12S voltage systems. The 7–9 kg single-axis payload figure applies when the motor is used with 36-inch carbon fiber propellers. When planning the frame interface and propeller adapters, check the mounting-hole patterns and the 15 mm shaft dimension against your hardware.
