AF Servo Motors

COMPACT SERVO MOTORS WITH HIGH POWER DENSITY

Moog AF series (12 poles) servo motors with natural cooling are designed for dynamic servo applications where small dimensions (especially shorter length) and high torque, along with a wide speed range and variable load, are required. From an electromagnetic standpoint, AF motors are designed for an overload capacity of 3–5 times the rated torque. Therefore, these servo motors can be used with torques substantially higher than those produced at nominal speed. They also offer a large power range, achieving continuous stall torque values from 2.8 to 65 Nm [25–575 lb-in].

The modular design of the AF servo motor supports a variety of options. In addition, Moog can provide fully customized solutions including: 

  • 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) 
    • different voltage constants (from about 1 to 500 V min. / 1,000)
  • Special rotors for higher speed applications with double or triple bandages
  • Special lightweight rotors for reduced inertia
  • Customized active lengths
  • Special mechanical designs for flange, bearings and shaft end for applications requiring higher radial and axial forces
  • Added environmental protection (higher temperature; hazardous or harsh environment)
  • Increased IP ratings
  • Variety of available encoder options
