Alternating synchronous servomotors have three-phase winding and permanent magnet on the rotor in their stator. Winding is designed for sinusoidal current and voltage. A thin layer of magnet made of rare rocks neodymium / iron / boron covers the surface of the rotor shaft, securing low rotational inertia. Segmental array of magnets on the rotor and sloping of mortises in the stator reduce momentary pulsations. These standard six-pole motors represent an ideal balance between angular velocity and voltage frequency.

Segment Servomotors Series H

Due to growing demands for minimization and low speed operation of servomotors, our company has developed a new series of servomotors – segment servomotors series H. The name segment servomotors is derived from the stator design. While in standard servomotors, winding is inserted into a completed stator, in segment servomotors each stator segment phase is wound separately prior to stator assembly. Segmental structure of the stator pack allows separate winding of each segment (pole-phase) before the completion of the stator. Separate segment winding provides better winding filling and higher density of magnetic field generated by the stator, as well as shortening of end winding. This results in a 40 – 50% reduction of the total length of the stator pack. Servomotors series H are shorter by 20 - 30% compared to servomotors series T of the same torque.
