MP-500 Brushless three-phase AC generatorDetailed product description：

MP-500 brushless three-phase AC generator

The MP series 500 base brushless three-phase AC synchronous generator is a new type of brushless generator developed and improved based on the MAGNAPLUS drawings provided by Marathon Electric USA in the United States.
The MP series 500 base generator is paired with a diesel engine to form a fixed or mobile power source, suitable for various occasions and can also be used as an emergency power source. MP series generators are unique in design, advanced in structure, excellent in performance, reliable in operation, convenient in use, suitable for various applications and climatic conditions, representing the current international advanced level.

Excellent electrical performance
1. Steady state voltage regulation rate ≤ 1%
2. Normal voltage regulation rate+20% -15% Un (60% In. cos with a hysteresis of less than or equal to 0.4)
3. Voltage regulation range>± 10% Un
4. The sine distortion rate of the line voltage waveform is less than 5%
5. Zero thermal deviation (extremely small)

Unique structural design
1. The generator is a fully protected structure with a unique internal ventilation and heat dissipation structure. The aluminum alloy fan has a high ventilation rate and low temperature rise.
2. Brushless excitation method, equipped with a solid-state voltage regulator, which has functions such as low-speed protection, electromagnetic interference suppression, over excitation shutdown, and stability adjustment and voltage amplitude adjustment.
3. The overall convex pole rotor structure integrates the damping winding with the rotor core, and the magnetic field winding is filled with thermosetting epoxy, which has high mechanical and electrical strength.
4. The rotating rectifier is located on the outside of the exciter rotor for easy maintenance.
5. The outlet box is spacious and can be equipped with various devices inside. The outlet box is located above and behind the machine base, beautiful and compact.
6. The insulation level is H-grade.
7. Modules and additional devices for parallel operation can be provided according to customer requirements.
8. The generator is divided into two structures: single bearing and double bearing.
The single bearing is equipped with international standard SAE interface and coupling plate, which can be matched with various imported oil engines.
Double bearings are suitable for various domestic diesel engines and can be equipped with various sizes of flange stops according to customer requirements.
9. PMG can be installed and DVR2000E digital voltage regulator can be used according to customer needs.
10. Anti condensation heating tubes and thermal protection components can be installed according to customer needs.

MP-500 brushless three-phase AC generator usage conditions
Air temperature not exceeding: 40 ℃
Altitude not exceeding: 1000 meters
If the usage conditions do not meet the above environment, the power output rating must be corrected according to regulations.
Voltage, frequency, speed, power factor, and operating mode
Rated voltage: 400 volts (480 volts at 60 hertz)
Rated frequency: 50 Hz or 60 Hz
Rated speed: 1500 rpm or 1800 rpm
Power factor: 0.8 lagging
Working mode: Continuous (S1)
According to customer needs, products with different output voltages or other special requirements can be made.

parallel operation
MP generators can operate continuously in parallel, and to ensure stable operation, the rotor is equipped with fully damped windings.
When the generator operates in parallel, the distribution of active load is regulated by the diesel engine governor, and the distribution of reactive load is achieved by the generator voltage regulator.
When generators equipped with SE350 are operated in parallel, APM2000 parallel modules and 5VA current transformers are required. Voltage sag or cross current compensation is used to ensure balanced distribution of reactive load between parallel generators.
A generator equipped with PMG and DVR2000E regulators, as the DVR regulator includes parallel operation function, only needs to provide a 5VA current transformer signal to the regulator.

Electromagnetic Interference Resistance
The generator equipped with SE350 voltage regulator meets the standard level, while the generator equipped with DVR2000E digital voltage regulator meets the MiL-461c standard

bearing
The bearings used in the MP generator are double-sided dust-proof rolling ball bearings, lubricated once and with special high-performance grease. Under normal use, B10 ≥ 20000 hours.
