AF Servo Motors

COMPACT SERIES WITH HIGH POWER DENSITY

Moog AF servo motors (12-poles) are designed for dynamic servo applications that require small dimensions (particularly shorter length) and a high torque along with a wide speed range and variable load. The AF series servo motors can be loaded with torques and currents substantially higher than the nominal ones. AF motors are designed for a torque overload capacity of 3 - 5 times the rated torque and offer a large power range. Standard AF series models deliver continuous stall torque values ​​from 2.8 to 65 Nm [25 - 575 lb/in].

The modular design of the AF series supports a variety of customizable options, including modifications in the following areas:  

  • Voltage constants (from about 1 to 500 V min. / 1000 V),
  • Winding and insulation systems 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 double or triple bandage
  • Special lightweight rotor for reduced moment of inertia
  • 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
  • Motors for special environmental requirements (higher temperature, chemical environment)
  • Motors with an increased IP address size.

Features

  • Compact dimensions with shorter axial length (flat motors) 
  • High torque overload capacity 
  • High efficiency 
  • High power density
  • Different winding options available
  • Long life and high operational reliability 

Benefits

  • Space-saving installation 
  • Highly customizable design 
  • Rugged design for minimal maintenance
  • Achieve greater precision with production and assembly
