Emax ES08MA II Servo Datasheet Write-up
5.1 Torque Curve (6.0V)
- Stall Torque: 2.0 kg·cm (beyond this, the motor stalls)
- Max Holding Torque: 2.2 kg·cm (brief peaks)
- Running Torque @ 1.0 kg·cm: 0.09 sec/60°
2.3 Torque (Stall)
| Voltage | Torque (oz-in) | Torque (kg-cm) | | :--- | :--- | :--- | | 4.8V | 21.7 oz-in | 1.6 kg-cm | | 6.0V | 25.0 oz-in | 1.8 kg-cm |
Interpretation: 1.8 kg-cm is respectable for a 13-gram servo. This means the servo can hold a weight of 1.8 kilograms at the end of a 1 cm horn. Practically, for a 5 cm horn, it can lift roughly 360 grams. This is ideal for small robotic grippers or micro RC car steering.

2.5 Current Drain
- Idle: 5 – 10 mA
- Operating (no load): 150 – 200 mA
- Stall: 800 – 1100 mA (1.1A peak)
Critical Note for Builders: Do not power this servo directly from an Arduino or Raspberry Pi 5V pin. The stall current over 1A will brown out your microcontroller. Use a dedicated 5V UBEC (Battery Eliminator Circuit) or servo driver board with external power. Emax Es08ma Ii Datasheet
Emax ES08MA II Datasheet: The Complete Guide to This Metal Gear Servo
Conclusion: Is the Emax ES08MA II Right for You?
The Emax ES08MA II datasheet reveals a servo that punches above its weight class. For under $10 (often $6-8 in bulk), you get metal gears, dual ball bearings, and a reliable analog control system that works with virtually every microcontroller and RC receiver.
When to choose the ES08MA II:
- You need durability without breaking the bank.
- Your project operates at 5-6V (USB, 4xAA, or 2S LiFePO4).
- You have space for a 23x12mm footprint.
When to look elsewhere:
- You require digital servo precision (e.g., for camera gimbals).
- You need continuous rotation (modding is possible but not recommended).
- Your voltage is fixed at 3.7V (1S LiPo) – the ES08MA II will be sluggish.
By keeping this guide bookmarked, you have a living datasheet that explains not just the numbers, but the practical reality of using the Emax ES08MA II in your next robotic or RC creation. Emax ES08MA II Servo Datasheet Write-up 5
