The A-080 permanent magnet DC brush type servomotors provide high torque with high velocity accuracy. Designed for long life and high reliability, the motors meet MIL standards.The motors are totally sealed to ensure long life in harsh environmental conditions.Their integral tachogenerator enables velocity servo-control.When mated with a positioning controller, the A-080 motors will provide an accurate, dynamic response for demanding positioning systems.In spite of their compact design, the motors can withstand large axial and radial forces on the output shaft.
