AML Servo Motors


Moog fan-cooled AML servo motors (6-poles) with separate ventilation are designed for highly dynamic servo applications that require a wide speed range and variable load. Its continuous torque and power output capabilities are up to 1.5 times greater than those of its basic variant, the AM model, while the size remains almost the same.

Motors with separate ventilation are most often used when higher power density is required and a water-cooled option is not suitable. The Moog AML servo motor series offers one of the largest power ranges in the industry, with standard models delivering continuous stall torque values ​​from 1.72 to 194 Nm [15.2 – 1716 Ib/in]. Its modular design supports a variety of custom options. In addition, Moog application engineers are available to help you achieve fully customized solutions that meet your precise specification requirements.

Customizable options include modifications in the following areas:

  • Totally enclosed fan-cooled motor, where cooling air is provided by fan mounted directly on the shaft
  • Winding designed for different voltage constants (from about 1 to 500 V min. /1000 max)
  • Winding system and insulation designed for different intermediate circuit voltages (12 V, 24 V, 48 V, 330 V, 560 V and 700 V DC)
  • Special rotor for higher speed applications with multiple bandages
  • 2 or 4 pole variants for high speed motors
  • Active lengths
  • Mechanical design of flange and shaft end
  • Bearings for special applications requiring higher radial and axial forces on the shaft end
  • Different types of encoders


  • High torque and speed capacity
  • Compact design
  • High efficiency performance
  • Long life and high operational reliability 


  • Highly customizable design
  • Low inertia
  • High acceleration in transient conditions
  • Minimal maintenance due to rugged design
  • High power density 
  • Achieve greater precision with production and assembly
