This is a universal motor dynamometer (dyno) that measures the rpm, kv, voltage, current draw, power and torque output of a electric motor. This dyno is great tool for motor analysis, ESC (boost) adjustment, brushless sensor adjustment, gearing calculation, etc. The dyno is coupled to a 540 motor or a Outrunner motor 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 motor. Our dyno repeatedly measures and calculates power in small increments to produce an accurate graph on a PC of the engine’s power characteristics. 

SAFETY FIRST

The dyno uses a high quality 6061 aluminum frame cover around the flywheel to protect from high rpm motors. Yet we still offer the ability to see the flywheel spinning action by adding a clear window screen. In addition, a clear Plexiglas shield covers the belt to protect from possible belt breakage.

FLYWHEEL

The flywheel design is the heart of the dyno. We offer different sizes and materials to best suit your motor application. Additional flywheels can be purchased separately.

FIXED BASE

Screw into baseboard to securely fasten the dyno. Screw #3 is optional. 

MOTOR HOLDER

Select two type of motor holders: (1) 540 motor holder, and (2) Outrunner motor holder. 

MOTOR PULLEY

The dyno includes two size of pulleys: 3.175mm, and 5mm bore to use with Outrunner and 540 motors. 4mm bore can be purchase separately.

PREMIUM BALL BEARINGS

The flywheel incorporates a set of 2 high-speed, black-sealed, steel ball-bearings throughout the assembly to ensure maximum efficiency. 

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.

ELECTRONIC BOARD

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.

PC APPLICATION

The dyno includes the software to analyse motors
