AML Servo Motors


Moog's 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. Motors with separate ventilation are most often used when higher power density is required and a liquid-cooled option is not suitable. The continuous torque and power output capabilities of the AML series are up to 1.5 times greater than those of its naturally cooled variant, the AM series, while their sizes are almost the same. The 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 - 1,716 lb/in].  Moog can provide fully customized solutions.

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 systems and special insulation options for different intermediate circuit voltages (12 V, 24 V, 48 V, 330 V, 560 V and 700 V DC)
  • Wide range of different voltage constants (from about 1 to 500 V min. /1,000 max)
  • Special rotor for higher speed applications with double or triple bandages
  • Active lengths
  • Special mechanical design for the flange, shaft end and bearings for applications requiring higher radial and axial forces 
  • Different types of encoders available
