Design features
1.Shunt excitation circuit (SHUNT)
The excitation is carried out according to a parallel excitation circuit, the excitation winding is connected in parallel to the armature. The motor is adapted to power from a 220 V DC network and maintains a stable rotation speed during voltage fluctuations, which meets the requirements for stability of pump speeds.
2.Protection and cooling
The IP54 housing protection℃provides effective protection against dust and splashing water, which allows the motor to be used at thermal power plants and pumping stations. IC411 cooling method (with built-in fan) ensures efficient heat dissipation at rated speed, ensuring stable operation in continuous operation.

3. Insulation and temperature conditions
Thermal class of winding insulation - 180 (class H). The windings are processed using vacuum -press impregnation (VPI), which ensures low heating, moisture resistance and durability. The engine operates stably at ambient temperatures from 0 to +40 degree.
4. Bearings and mounting design
The shaft is equipped with sealed ball bearings 6312/2RZ and 6212/2RZ, which provide long service life without maintenance. The rigid design of the frame is adapted for both vertical and horizontal installation, and is highly resistant to vibrations and shock loads.
5.Precision manufacturing
The rotor is subjected to high-precision dynamic balancing. Rated speed - 2950 rpm, which ensures low vibration and noise levels during operation. The compact design, weighing only 648 kg, simplifies installation and on-site servicing.
Product benefits
1.High adaptation to working conditions
Specially designed to drive pumps. The high rotational speed (2950 rpm) combined with parallel-excited speed stability provides a constant torque output, allowing direct drive of pumps to meet both emergency and continuous water supply requirements.
2.High operational reliability
The combination of class H insulation, IP54 protection℃and sealed bearings ensures stable operation in difficult conditions: high humidity, dust, voltage fluctuations. This significantly reduces the risk of equipment failures and downtime
3.Excellent starting performance and fast response
DC motors have high starting torque and fast response. The shunt circuit allows the battery to instantly start the engine when AC power is lost, ensuring safe emergency water supply to critical systems.
4.Low operating costs
The parallel excitation design is proven and reliable. The brushes and commutator have a long service life, and the sealed bearings do not require regular maintenance. Spare parts are standardized, and the SIMO service network throughout Russia provides timely support, reducing maintenance costs
5.Compliance with safety standards
The products are CE certified and comply with industry regulations. Built-in overload and overheat protection systems meet safety requirements for thermal power plant and pumping station facilities, ensuring the safety of personnel and equipment.
