Miniature AC servomotor with high torque and high-resolution
DDmotor has characterristics of low speed and high torque (compared to general servo motors) because this motor is assumed that it will drive directry without using a gear(a deceleration mechanism).
Its equipped sensor specialized in high-precision positioning, and It is possible to receive the shaft load directly by adopting high-load bearing as standard.
Advantages that can be generally obtained by using a gearless structure are described below.
Servo driver
we selected a number of suitable drivers for the miniature Servomotors
