The SANYO DENKI SERVO SYSTEMS need one or more input signals in basic or complicated configurations, based on the technical requirements of the motion mechanism. These systems are normally AC synchronous brushless motors having built-in position inputs. They are utilized in closed-loop motion control systems where angular direction, speed as well as torque can be controlled very precisely. They use permanent magnets that can be indefinitely located between the magnetic poles on the stator by adjusting the voltage and current around the windings. Moreover, the SANYO DENKI SERVO SYSTEMS are best suitable where precise control of rpm, torque, etc., is needed.
