1-2Overveiw of the Product11.1 About the DYNASERV DM/DR SeriesThe DYNASERV servo motor, is a high speed, high torque, and high precision outer rotor type direct drive motor.The DM series motors are contained in an aluminum chassis and have a built-in optical encoder. There are fourmodels in the A series with output torques of 50 to 200N⋅m and five models in the B series with torques of 15 to75N⋅m. The outside diameters are 264 mm for the A series and 160 mm for the B series. Each has a shaft hole of58 mm and 25 mm in diameter at the center, respectively.The outer shapes of the small-diameter and flat type DM series motors have successfully been made flatter andsmaller in diameter based on the basic performance of the conventional DM/SD series. An outer diameter of 116mm and a height (thickness) of 45 mm, respectively, are achieved for the DM small-diameter type and the DMflat type.Both types are equipped with an optical encoder, which is characteristic of the DM series, and have the addedfeatures of high resolution and high mechanical precision. They are actuators with excellent output-to-spaceratios and the best available option for servos for semi-conductor manufacturing devices, precision test devices,etc. They can be used in various applications.The DYNASERV DR series is a series of operational direct drive motors that was developed based on the field-proven DM series to satisfy new demands. There are six A type models (50 to 400N⋅m) with an outer diameterof 264 mm (10 inches), seven E type models (30 to 250N⋅m) with an outer diameter of 205 mm (8 inches), andfive B type models (8 to 60N⋅m) with an outer diameter of 150 mm (6 inches). In addition, there is a 5000B/Etype (consisting of five high-speed type models).Moreover, in addition to the above standard models, several special type models are also available, such as light-weight types, types with flanges, types with brakes, and high mechanical precision installation surface types.
