Dc motor and ac motor, which is better for mechanical hands?
DC power amplification, but not to control steering servo DC signal, and is adjustable wide pulse signal, so as to obtain the high precision control. Pure DC signal can also control the rudder Angle, but control may be too long, for example, if you need to 31 degrees from left 30 degrees to the left, with DC signal may need to 1 second, and using PWM pulse may need only 0.1 seconds
With the second floor. The mechanical hand USES dc servo motor more.
The manipulator USES servo motor and pulse motor to be controlled accurately.Dc motors should be used in this way.
