MINIPRO’s Slot Car Inertia Motor Dynamometer (Dyno) was designed for testing FA130 and FK180 slot car brushed motors. The load on the motor is produced by the inertia flywheel unit - a high quality 6061 aluminum frame cover around the flywheel to protect from high rpm speeds; and an embedded dyno board to accurately measure the acceleration of the DUT (device under test). 

The dyno is coupled to a motor holder via a pulley and belt to accelerate the inertial mass (flywheel). Our embedded dyno board takes the flywheel’s inertia (resistance of an object to a change in its state of motion), and measures the rate it takes to accelerate it and calculates the output power and torque of the DUT. Our dyno repeatedly measures and calculates power in small increments to produce an accurate graph on a PC of the motor’s power characteristics.

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. Our dyno is capable of repeatable test results using the Throttle Controller Board (sold separately).

IMPORTANT: An Electronic Speed Control (ESC) and Voltage/Current sensor are required to measure voltage, current, power-in and efficiency. Throttle Control Sensor is required to control your ESC with the software. We reserve the right to change the color(s) of any component(s) of the dyno without prior notice.
