How does the IMW Motorchecker work

The IMW Motorchecker is a flywheel - motorchecker. The motor is powered with a electronicly regulated, simulated 6 cell 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.
