A-063 Motors
The A-063 permanent magnet DC brush type servomotors provide high torque with high velocity accuracy. These motors are designed accding to tough military specifications and are totally sealed to ensure high reliability and long life in harsh environmental conditions.In spite of their comact design, the A-063 motors can withstand large axial and radial forces on the output shaft. When mated with positioning controllers, they will provide an accurate, dynamic response for demanding positioning systems.
