miniPRO Chassis Dyno

miniPRO USA have introduced their Chassis Dyno, a chassis dynamometer (dyno) that measures the rpm, kv, voltage, current draw, power and torque output of your vehicle. This dyno is great tool for motor analysis, ESC (boost).

This dyno is great tool for motor analysis, ESC (boost) adjustment, brushless sensor adjustment, gearing calculation, tire selections, and much more. The dyno is coupled with to a knurled roller via a pulley and belt to accelerate the inertial mass. We will call this a ‘flywheel’ for simplicity. Our electronic board takes the flywheel’s inertia (resistance of an object to a change in its state of motion), measures the rate it takes to accelerate and calculates the output power and torque of your vehicle. Our dyno repeatedly measures and calculates power in small increments to produce an accurate graph on a PC of the engine’s power characteristics.

The dyno is suitable for 1/12, 1/10, and 1/8 gas or electric vehicles. It incorporates an adjustable wheelbase design for up-to 370mm of allowable wheelbase; and 375mm of vehicle width.

The chassis dyno gives you the option to increase or decrease inertia at the rollers. We incorporated a modular design that allows you to add up-to two flywheel housing (same as the motor dyno) to increase the inertia. This allows you to test high torque vehicles. Inside these cases is the flywheel (heart of the dyno). miniPRO offer different sizes and materials of to best suit your vehicle application. Additional flywheels can be purchased separately.

The chassis dyno uses the same flywheel housing as the motor dyno – a high quality 6061 aluminum frame cover around the flywheel to protect from high rpm vehicles. Yet miniPRO still offer the ability to see the flywheel spinning action by adding a clear window screen. The flywheel incorporates a set of 2 high-speed, black-sealed, steel ball-bearings throughout the assembly to ensure maximum efficiency.

The base of the dyno includes four foam pads to reduce the vibration of the vehicle. The profile guide rails incorporate holes as an option for fixing the base on a table. Full Size Car Dynos are know for their famous belt-striping feature, and our dyno is not an exception. The chassis dyno includes four belt stripes to fix your vehicle. In addition, the Upper Deck slides back/forward to adjust the tension. The chassis dyno is very easy to maintenance. It incorporates a roller bearing housing design for easy maintenance and replacement of bearings.

Precise, otherwise known as “Repeatability” is what you want in a dyno, that means test the same electric motor time after time and get the same results. The dyno is capable of repeatable test results. The dyno uses a custom PCB with a build Optical RPM sensor, delivering low noise and accurate readings. It features a built-in micro USB for connection to your PC. It includes one external LCD port, one external throttle controller port, one current and voltage sensor port, and two temperature sensor ports.

Technical specifications:

  • Torque: 2N/m Max (with GT2 2mm Belt)
  • RPM: 100K Max
  • Units: English & Metric
  • Adjustable Reading and Logging Rate: Up to 50Hz

    This is not a dyno. It’s an accelerometer. After a couple of seconds when the flywheel is up to
    speed, there is no load. In our testing, we found that many motors can
    look good on one quick pull, but fall on their face after a couple of
    minutes of race simulated controlled load. That’s because some motors
    are better than others at creating heat and removing it.
