R/C Car Inertia Motor Dyno V2

This new MINIPRO’s R/C Car Inertia Motor Dynamometer (Dyno) V2 was designed for the testing all types of R/C motors, brushed or brushless. 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 uses a pinion/gear combination 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 built-in Throttle controller sensor (license required).

SAFETY FIRST

The dyno uses a high quality 6061 aluminum frame cover around the flywheel and shield around the gear to protect from high rpm speeds produced by your motors. Yet we still offer the ability to see the flywheel spinning action by adding a clear window screen. 

FLYWHEEL (VARIABLE LOAD) 

The dyno uses the motor to simply accelerate a flywheel (variable load). We calculate the mechanical power and mechanical torque of the motor by knowing the flywheel's inertia (resistance of an object to a change in its state of motion), gear ratio and it's acceleration. We offer different sizes and materials to best suit your motor application. Additional flywheels, pinions and gears can be purchased separately. 

ALUMINUM BASE 

Aluminum 6061 base equipped with anti-vibration foot pads. Portable design that allows you to install your ESC and sensors. No additional base required. 

MOTOR HOLDER

Easy install and remove tested motors and keeps the same gearing relationship for repeatable and reliable tests. Attach multiple sensors on the same motor holder to keep the unit easy assessible and compact.  We offer different sizes of motor holders. Image below shows optional sensors; voltage and current, I.R. temperature sensor and BLDC RPM sensor.

 

PINION AND GEAR SYSTEM

The dyno uses a pinion and gear configuration to remove side load friction losses and provides an easier setup between test motors. A pinion is installed on the test motor and a gear is installed on the flywheel. The gear on the flywheel has a one-way clutch bearing to remove deceleration wear from the motor. Additional size pinions and gears can be purchase separately.

LOW FRICTION CERAMIC BALL BEARINGS

The flywheel incorporates a set of 2 low friction ceramic ball-bearings throughout the assembly to ensure low mechanical losses and maximum efficiency.
 

CONTROLLER BOARD 

The newest dynamometer controller V3 offers a faster processor, lower noise and newer software (V5). It features a built-in throttle control sensor (license required) and micro USB for connection for your PC. It includes one external LCD/UART port, one digital temperature port, one voltage and current sensor port, one external rpm sensor port, one flow sensor port, two analog temperature ports, one thermocouple port, and one aux port. 

PRECISE TEST RESULTS

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 built-in throttle control sensor (license required) or an the external throttle control sensor.
