Abstract

In recent years, many electrically powered vehicles are developed and produced on the whole world. Most of these products are driven by a single large electric motor instead of a gasoline engine. Generally, high power motors have problems that both of the maximum rotational speed and the responsiveness are lower than small motors. We consider Multi-Motor Power Unit can solve their problems. Multi-Motor Power Unit consists of many small DC motors and their outputs are transmitted to driving shaft through gears. We developed Gear-Train-Type Multi-Motor Power Unit that is improved from the basic idea of Multi-Motor System, and it keeps 1:1 gear ratio. Gear-Train-Type Multi-Motor Power Unit has a problem that the center gear loading all motor's output has to be large module. We had proposed new Multi-Motor Power Unit and named it as Tandem-Type Multi-Motor Power Unit. We had developed small-sized Tandem-Type Multi-Motor Power Unit and experimentally measured the maximum torque of it.
