Emax Es08ma Ii: Datasheet Upd

The EMAX ES08MA II is a compact and lightweight brushless motor that offers high efficiency, reliability, and durability. It is designed to provide a high power-to-weight ratio, making it suitable for applications where space and weight are limited.

| Parameter | Value | | :--- | :--- | | | 4.8V – 6.0V (4.8V nominal, 6.0V max recommended) | | Stall Torque | 2.0 kg·cm @ 4.8V / 2.5 kg·cm @ 6.0V | | Speed | 0.12 sec/60° @ 4.8V / 0.10 sec/60° @ 6.0V (no load) | | Dead Band Width | ≤ 5 µs (typical) | | Rotation Angle | 180° (approx. 1200–1800 µs PWM; 90° per side typical) | | Connector | JR/Futaba type (3-pin 0.1" spacing) | | Wire Gauge | 28 AWG, ~150mm length | | Dimensions | 23 x 12.2 x 27 mm (L x W x H) | | Weight | ~12.8g ± 0.5g |

Ensure your external power supply shares a common ground (GND) wire with your microcontroller. Jittering can also indicate an insufficient power supply dropping voltage under load.

Used for swashplate linkages and tail rotor controls on micro-helis.

Despite weighing only 12 grams, it provides up to 2.0 kg·cm of torque at 6V.

The is one of the most popular micro servo motors in the robotics, RC aviation, and DIY electronics communities. Known for its high torque, durable metal gears, and affordable price point, this servo is a staple for projects requiring reliable actuation in a compact footprint. The EMAX ES08MA II is a compact and
