DYNertia3 Quick Start (Inertia- Chassis type)

Concept

An inertia type dyno operates on the principle of calculating the power required to accelerate a known mass, which is

basically just an additional 'roller/flywheel' driven by the vehicle. The controller senses the velocity of this rotating mass,

handles the precision timing required and outputs this data to the PC for analysis and storage.

The included 'DYNertia3' software package handles all the functions required for dyno control, setting up, saving runs,

correcting for atmospheric conditions, filtering, displaying data, printing, overlaying and analyzing multiple runs.

Hardware Mounting & Basic Wiring for Initial Setup

Mounting the DYNertia Sensor and Magnet

Mount the sensor system to detect the rotation of the roller/shaft.

Note:

Do not mount the magnet at the outside diameter of the dyno roller/shaft as the centrifugal forces will be highest;

choose a location towards the centre area. The magnet is also very fragile and must be handled with care!

The included sensor will only detect the 'South' Pole of a magnet, so the magnet must be have the South Pole

Note:

Magnet epoxy glued and screwed to dyno flywheel with South Pole outwards.

Mounting by screwing/gluing flat to dyno flywheel-

Dyno flywheel is drilled and tapped for 3mm screw (2.5mm drill size is

usual for 3mm tapping). Short (min 6mm) screw inserted into magnet.

Do not over tighten or magnet may crack!
