Single Roller Dynamometer, MSR 1050

Single Roller Dynamometer

VP 230034


  • Test speeds of up to 320 km/h
  • Electronically-controlled synchronisation of the speed of the front and rear roller set for current and future drive concepts with active power distribution
  • Large roller diameter 762 mm (30Ž)
    • Tyre rolling action as it would be on the road
    • Tyres are preserved as a result of limited flexing action
  • Optimum reproducibility
  • Simple restraining mechanism for quick vehicle fixation

High level of flexibility in use due to extensive variety of operating modes, covering all fields of application:

  • Static power measurement at constant RPM
  • Static power measurement at constant speed
  • Static power measurement at constant tractive force
  • Dynamic power measurement with adjustable acceleration
  • MAHA towing power measurement guarantees the highest degree of accuracy when measuring power:
    Precision calculation of the parasitic losses of the dynamometer, of the vehicle’s drive train and the tyre to roller friction and flex losses
  • Tachometer testing with up to ten freely selectable test points
  • Distance measurement included
  • Stopwatch function for measurement of acceleration between optional speed markers as standard
  • Optional load simulation with freely programmable load profile
  • Optional driving simulation with freely programmable speed profile
  • Option of storing programmed profiles in database

Professional, intuitive-use software for the highest expert standards with:

  • continuous graphic display and recording of up to 16 freely selectable parameters per performance measurement cycle on one measurement screen.
  • In addition to the current performance measurement cycle, fade-in of up to three stored cycles on the measurement screen for optimum comparability during calibration work
  • Two circular dial displays for RPM and speed as well as current oil temperature display, ensuring constant control of key parameters during performance measurement
  • Determination of wheel power, power dissipation, engine power and torque
  • Standardised extrapolation of motor power in line with DIN 70020, EEC 80/1269, ISO 1585, JIS D 1001 and SAE J 1349 (configuration-dependent)
  • Circular dial display of motor power, RPM, speed and tractive force during simulation cycles
  • Colour-highlighted user prompts integrated within the circular dial facilitate the accurate reproduction of simulation cycles
  • With radio remote control as standard for complete control of the dynamometer from within the vehicle.
  • Radio remote control with long-life battery and charging station
  • Cooling fan switched on and off either at the control console or with the radio remote control
  • With interface box including stand and long connection cable as standard for optimum placement at the dynamometer with MAHA plug-in CAN-DRZ module card for connecting RPM sensor.
  • Interface box optionally upgradeable with MAHA plug-in card for comprehensive recording of external Ambient data such as air temperature, air pressure, rel. humidity and intake temperature
  • Interface box optionally upgradeable with MAHA plug-in analogue input module card with 4 sensor inputs for temperature and pressure sensors or lambda sensors.
  • Optional connection of MAHA MGT 5, MDO 2 LON and MET SERIES emission testers
  • Optional connection of Krupp/AIC fuel consumption measuring instruments for petrol- and diesel engines
