I am a student of electrical engineering and
one of my hobbys is R/C - Car - Racing. I built and drive for about 10
years Electric - Offroad - R/C - Cars. At the moment a drive as a german
team - driver a S.P.O.R.T.
Yokomo 4WD and a Team Losi XX 2WD.
As a team - driver for the german manufacturer
GM - Racing, i use TEAM
EVOLUTION Motors, a HEL

Version for Windows
How does the IMW Motorchecker work
- The IMW Motorchecker is a flywheel - motorchecker.
The motor is powered with a electronicly regulated, simulated NiCd - battery
and accelerats a flywheel, which is mounted on the motorshaft, from standstill
until the maximum R.P.M. of the motor.
- During this process the current, voltage and R.P.M.
is measured.
- The torque is calculated from the acceleration of
the flywheel, and the mechanical power is callculated from the torque with
the depending R.P.M.. The efficiency is the relation of the mechanical
power and the electrical power, which is calculated from the current and
voltage.
Technical Data
