* The exact parameters are listed on the engine model pages.
AC motors with a closed-loop rotor. They are designed to drive mechanisms with difficult start-up conditions that do not require speed control (pumps, fans, smoke pumps, etc.with similar starting characteristics), including those placed at nuclear power plants (NPP).
Optionally, the DAZO4 series is available in a low-voltage version.
Long-lasting rotor winding
Aluminum welded winding, compared with cast, which is prone to cracking, is more reliable and maintainable. In addition, its rods have a larger cross-section, which reduces their heating.
Updated ventilation and cooling system
An external blower fan with a smaller diameter but longer length is installed, and the configuration of its blades has been changed. A new casing is used to increase the volume of refrigerant flowing through. This configuration of the ventilation and cooling system ensures optimal heating of the active parts of the engine, eliminating local overheating. It also reduced noise, increased efficiency, and increased service life.
Convenient pin box
The terminal box with 6 power pass-through terminals provides convenient switching of the star/triangle winding connection scheme with jumpers, which does not require dismantling the box body. Control insulators are installed to connect the sensor circuits.
Reliable insulation of the stator winding
The absence of overheating of active parts in operating mode increases the reliability and durability of insulation of the stator winding and the motor as a whole.
Reduced vibration level
Due to the increased rigidity of the bed, the use of thicker legs, and the improved design of the stiffeners, the vibration level is reduced twice, which increases the reliability of the engine during overloads and increases its service life.
An effective system reset/remove grease
A new grease replenishment and discharge system has been applied, which makes it possible to remove grease without dismantling and disassembling the electric motor.
