Specialized for low speed, high torque, and high precision positioning! Gearless AC servo motor "μDDmotor"
<Low Speed, High Torque> To use in gearless or low reduction ratio applications, it is necessary to output a higher torque than conventional motors. The μDD motor achieves five times the torque of traditional motors (for the same size). <Standard High-Precision Bearings> Since the motor shaft must directly bear the load, its rigidity must be high. The μDD motor addresses the conflicting demands of high-precision assembly and high load capacity by standardizing the use of angular bearings. <Equipped with High-Precision Positioning Sensors> By incorporating a high-resolution encoder in a compact design, it specializes in fine positioning. Additionally, using a driver compatible with high-precision sensors allows for highly responsive control. By utilizing high back-drivability for current monitoring (safety alarm function), it prevents motor burnout.
