First, because of the torque constant "220V Cooling Fan" high performance materials leaving the motor torque inertia ratio, power density is greatly improved. By rational design but also make the moment of inertia, electrical and mechanical time constants and other indicators is greatly reduced, as the main indicator of servo control performance has been greatly improved.
Second, "220V Cooling Fan" modern magnetic circuit design has been more perfect, with high coercivity magnetic material, and thus anti-armature reaction and its ability to resist demagnetization of the motor greatly enhanced with the motor control parameters External influences disturbances greatly reduced.
Third, due to the "220V Cooling Fan" to replace the electric magnet excitation, reducing the field winding and the exciting field of design, thus reducing the magnetic field flux field winding inductance, the excitation current, and many other parameters, thereby directly reducing the controllable variables or parameters.
