Permanent Magnet A.C. Synchronous Servo Motor can be operated from single phase source with R-C Phase shifting network and the speed of the motor is proportional to applied frequency of the supply. The Servo Motor attains its full synchronous speed within 5 to 25 ms and comes with various types of torque capacities of 3, 10, 20 and 40 kg.Cm. The Servo Motor is made of quality grade copper, stampings, milmex paper, varnish, inner, rods and shafts which ensures optimum durability along with long lasting trouble free service. Permanent Magnet A.C. Synchronous Servo Motor is designed with magnetically rotor which can be locked by D.C. Applying.
