Most torque converters have a stall speed around 2000 - 2500 RPM. Which also happens to be the RPM range that your vehicle normally runs at cruising speed. At a lower speed you would be simply running a viscous coupling between the engine and transmission.
Then, thereâs the obvious choice: A dynamo attached to one of the bike wheels. (These devices in general are called generators, but when attached to a bike, a generator is traditionally referred to as a dynamo.
dyÂ·naÂ·momÂ·eÂ·ter [dahy-nuh-mom-i-ter]. A dynamometer or dyno, is a test instrument used to measure torque and speed, which is used to calculate power of a device such as an engine, electric motor, pump, transmission, or generator/alternator.ynamometers can be either motoring, in which a dynamometer has a motor that can drive the device under test, and/or absorbing where the torque and speed is determined by the power produced.
