Woodward 5484-803 Governor PM Motor

Description

Woodward 5484-803 Full Introduction & Technical Specification
Basic Product Information
Brand: Woodward
Model: 5484-803
Official full product name: Permanent Magnet Governor PM Motor (Diesel Engine Speed Control Actuator Motor)
Place of origin: United States
Customs HS Code: 85011099 (low-power permanent magnet DC servo motor for industrial engine speed control)
Physical Dimension & Weight Parameters
Overall outline dimension: diameter 52 mm, total axial length 86 mm, square mounting base size 40 mm × 40 mm;
net weight of the complete motor assembly is approximately 0.46 kg;
outer shell is made of thickened anti-rust steel shell, internal rotor adopts high-performance rare-earth permanent magnet structure, output drive shaft is quenched wear-resistant steel;
standard four-hole fixed base installation structure, reserved standard plug wiring terminal, convenient on-site wiring and disassembly replacement;
overall protection grade reaches IP44, effectively preventing liquid splashing and fine dust invasion.

Electrical Voltage & Current Parameters
Rated standard operating voltage: 24 V DC direct current;
quiescent no-load operating current: 65 mA;
rated continuous operating current: 220 mA;
maximum instantaneous locked-rotor current: 580 mA;
fixed rated rotation speed: 4 RPM constant low speed;
internal coil resistance: 32 Ω;
polarity definition: positive pole (red wire) for speed increase, negative pole (black wire) for speed reduction, reverse connection will lead to reverse rotation of the output shaft;
insulation grade of internal winding: Class B, with built-in overcurrent protection fuse inside the coil.
Environmental Adaptation Parameters
Normal continuous operating temperature range: -30 ℃ ~ +75 ℃;
allowable short-term peak operating temperature upper limit: +85 ℃;
storage and transportation temperature range: -45 ℃ ~ +90 ℃;
applicable ambient humidity range: 5% ~ 98% non-condensing humidity;
vibration resistance conforms to IEC 60068-2-6 industrial vibration standard, resisting long-term mechanical vibration and impact of engine operation;
built-in simple RC filtering circuit, capable of suppressing power supply surge and low-frequency electromagnetic interference on site.
Core Functional Characteristics
Firstly, ultra-stable low-speed constant rotation performance, fixed 4 RPM low-speed design avoids excessive fuel adjustment amplitude, ensuring high precision speed fine-tuning for engines, effectively controlling speed fluctuation range within ±0.5% rated speed.
Secondly, fast dynamic response capability, the motor can complete full stroke mechanical adjustment within 0.3 seconds after receiving electrical signals, rapidly coping with sudden load increase or decrease of generator sets to prevent overspeed and stall faults.
Thirdly, strong environmental durability, anti-rust shell and sealed internal structure adapt to marine engine room, mining equipment and outdoor harsh industrial environments, no easy aging of internal magnetic components, long service life.
Fourthly, universal system compatibility, perfectly matched with almost all mainstream Woodward analog and digital governor controllers, also compatible with most domestic and international diesel engine electronic speed control systems, standard interface realizes plug-and-play replacement without complicated parameter calibration.
