8440-1955 WOODWARD Speed Sensor Full Series

8440-1955 Product Introduction

 
8440-1955 Details:
 
 
The WOODWARD 8440-1955 speed controller has a series of significant product features that make it an ideal choice for engine or generator speed control in industrial applications. The following are its main characteristics:
 
Wide application range: This speed controller can be used in diesel engines, gas engines, steam turbines, or gas turbines, with a wide range of applicability.
Flexible signal input: This controller can set the speed or load of the device based on computer control signals of 4-20mA or 1-5 Vdc, providing users with multiple options to meet different control needs.
Multiple working modes: This controller has two working modes: zero difference adjustment and differential adjustment.
Non differential regulation is mainly used for constant speed control and is suitable for single machine operation or multiple prime movers working together in an isolated power grid. Differential regulation provides more control flexibility.
Highly integrated: This speed controller can be used in conjunction with a range of Woodward devices, such as power automatic transferors, input-output controllers, generator load controllers, etc., to achieve more comprehensive system control.
Rich additional functions: In addition to basic speed or load control functions, the controller also has functions such as synchronous or deceleration control, high and low speed adjustment, and fuel limit for override start,
further enhancing its performance and application range.
High precision output signal: The output signal provided by the controller is proportional to the fuel setting required to achieve the desired speed/load, ensuring precise control.
Durable and sturdy: The design takes into account the complexity of industrial environments, allowing the controller to operate stably under various harsh conditions.
In summary, the WOODWARD 8440-1955 speed controller plays an important role in industrial applications due to its wide application range, flexible signal input, multiple working modes, high integration,
rich additional functions, and high-precision output signals. Whether it is in the fields of generator sets, compressors, pump stations, or ships and locomotives, it can effectively ensure the stable operation of equipment within the set range.

8440-1955 is manufactured by Woodward in the company”s easyYgen 3000XT series. The XT series has some updated features on the older 3000 series. Some new features include plug-in replacement,
power measurement level 1, editable screen, multi interface toolkit connection, etc. All details can be found in Woodward easyYgen manual 37582A
This model is the 3200XT-P1 (Package 1) version. A significant difference between the 8440-1955 and similar 3200XT-P1-LT models is their operating temperature range.
The rated operating temperature range of this model is -20 to 70 ° C; the rated temperature range of the LT model is -40 to 70 ° C, suitable for outdoor use.
8440-1955 is equipped with a monitor (not available on the 3100 model) and is designed for front panel installation.
The toolkit software used for controlling the generator set has multilingual functionality. English, French, German, and Japanese are just a few of the fourteen supported languages.
The built-in HMI has a color LCD and soft keys (now with dedicated buttons) for direct control of the 8440-1955 device. Multi level password protection can prevent unauthorized changes.
The easyYgen 3000XT model 8440-1955 has three freely configurable PID controllers. It provides input and output control (kW and kvar), as well as MCB and GCB synchronization (sliding/phase matching).
The generator set has four operating modes and the option to configure a manual circuit breaker control device.

The most fundamental reason for distinguishing these two motor types is that the design of the air gap magnetic field is different. So the following differences ariseThe back EMF waveform is different:BLDC: Approximate trapezoidal wave (ideal state);PMSM: sine wave (ideal state);The three-phase current waveforms are different:BLDC: Approximate square wave or trapezoidal wave (ideal state);PMSM: sine wave (ideal state);Differences in control systems:BLDC: usually includes position controller, speed controller and current (torque) controller;PMSM: Different control strategies will have different control systems;Controls are different:BLDC: 120-degree square wave current, using PWM control;PMSM: Positive Xuan wave current, controlled by SPWM SVPWM.However, in actual control, brushless DC can also be controlled by FOC, and permanent magnet synchronous motors can also be controlled by square waves.Just like the controllers of electric vehicles, I have disassembled and studied three or four. The interfaces are all the same, the control chips are different, and of course the control algorithms are also different. Electric vehicles controlled by sine waves have very low sound when starting and running, and there is no jitter during operation; but electric vehicles controlled by square waves have very obvious sounds, and the jitter during operation can also be felt. The judder is due to definite torque ripples.Motors controlled by square waves have higher power efficiency, because motors controlled by sine waves have a lower effective voltage.4. Control technology of permanent magnet synchronous motorPermanent magnet synchronous motors and brushless DC motors can be operated using the same control method.
