MSR 3000/4 VP 230050

product details / scope of delivery

4WD Single roller dynamometer for passenger cars
with two eddy current brakes on the rear axle with E-motor
and two eddy current brakes on the front axle with E-motor.
Suitable for tuning, diagnostic and development work
for especiallymodern single-axle as well as 4WD drive systems
of internal combustion and electric vehicles.

Product advantages:

• Test speed up to 300 km/h (optional 350 km/h).
• Fast, precise and powerful control of the eddy current brake through high-performance current controller for vehicles of all performance classes
• Electronically controlled 4WD synchronization through modern SPS control system for modern and future drive concepts with active power distribution
• Particularly suitable for testing of the most electric vehicles, due to the intelligent 4WD control technology
• Automatic mass determination (rotating mass of the vehicle) separately for each vehicle axle
• Smooth-running, low-vibrationroller set for high-precision measurement results
• High-quality, low-wear and low-maintenance design: Made in Germany
• Rolling and slippage behavior of the tire as realistically as possible thanks to the crown roller principle in

conjunction with intelligent control technology

• Tire-protecting, due to low flexing work
• Simple tensioning device for quick vehicle fixation (optional)

Description Measuring programs:
High flexibility of use due to extensive operating modes
which comprehensively cover all fields of application:

• Power measurement dynamic with adjustable acceleration
• Static power measurement with several measuring points
• Trailing power measurement for highest accuracy in power measurement. The parasitic losses of the test bench, of the vehicle's drivetrain and the friction and flexing losses of the tires to the roller, are determined with high precision
• Automatic mass determination (rotating mass of the vehicle) separately for each vehicle axle
• Load simulation static at constant rotation speed
• Load simulation static at constant speed
• Load simulation static at constant tractive force
• Load simulation static at constant acceleration
• Optional tachometer test with up to 10 freely selectable measuring points
• Optional distance measurement
• Optional driving simulation with freely programmable speed profiles
• Optional driving cycle - running of standardized cycles
• Optional storage of programmed profiles in the database

Description 4WD Roller Set:

• Electronically controlled synchronization of the speed of the front and rear roller set
• Two eddy current brakes front roller set
• Two eddy current brakes rear roller set
• Covering and shifting plates
• Hydraulic power unit with self-locking cylinder
• Adjustment of the center distance by means of MSR Remote Panel by shifting the rear roller set
• Painting high quality powder coating: anthracite gray, RAL 7016 (frame, cover and shifting plates)

Description Software:
Professional, intuitive software:

• Display of the speed of both axes in each mask available
• In addition to the current power measurement, insertion of up to three stored measurements in the background incl. additional values; for optimal comparison possibilities during tuning work
• Three display screens freely configurable for control of important parameters during power measurement
• Determination of wheel power, power loss, engine power and torque
• Standardized extrapolation of engine power for internal combustion vehicles according to DIN 70020, EWG 80/1269, ISO 1585, JIS D 1001 and SAEJ 1349 (depending on equipment)
• Power measurement for electric vehicles
• For electric vehicles, special test bench settings
• For electric vehicles, 2 speed inputs for independent power measurement of front and rear axle
• Freely configurable display of all input values in the available measurement screens
• Comfortable operation via wired MSR Remote Panel incl. emergency stop
• Symbols and icons for more clarity and intuitive understanding
• Voice prompts for the operator to control the test stand (optional)
• Modern user interface and color scheme with highlighted cursor position for easy orientation
• Database for storage of measurement results
• Storage of vehicle-specific settings (as well as all determined data including read-out OBD data)

Description of the SIEMENS SPS control system:

• Standardized proven control electronics from the industry always on the latest state of the art
• High-resolution input signals, highprocessor performance, fast and precise control of the actuators with a specially developed current controller with highest performance in the millisecond range
• Profi-Net bus communication of the SPS control system and components.

Description Interface box:

• Standard with environmental module to record ambient temperature and intake air temperature
• Expandable for recording additional data (Analog Input Module, Rotation speed, OBD interface, oil temperature)

Standard scope of delivery:

• Self-supporting closed roller set with two eddy current brakes for the front axle with E-machine
• Self-supporting closed roller set with two eddy current brakes for the rear axle with E-machine
• Hydraulic roller set adjustment with shifting plate set for 4WD floor assembly
• Roller coating Ni/Cr
• Switch cabinet for control of the test stand
• Test bench PC
• MSR Remote Panel cable-connected for control of the test stand
• Interface box with environmental module
