NTN Corporation (hereafter, NTN) has developed an “In-wheel motor system for electric commuters” which conforms to the functions and applications in two-seater electric commuters and one-seater electric minicars, while promoting the development and commercialization of “in-wheel motor systems”.

By applying an in-wheel motor system to electric vehicles (hereafter, EV), effective use of space, flexibility in the designing of the vehicle and design can be improved. As for future expansion, this system is expected to be used in an EV for use in short driving distances for shopping and commuting, an EV friendly to senior citizens which is easy to get in and out of, two-seater electric commuters suitable for practical use in EV towns and one-seater electric minicars.

The “In-wheel motor system for electric commuters” developed by NTN, achieved a smaller size and weight reduction which can be applied to electric commuters, by changing the mechanism of the hub bearing, reduction gear and motor, which are the component parts of the already developed “In-wheel motor system”.

Features

1. Compact in-wheel motor module which can be stored in the wheel
   • Commercializes slim type hub bearings
2. Systematization of the drive system of electric commuters in one unit
   • Drive motor, reduction gear, hub bearing and control system (including inverter)
3. Independent control of driving force of the right and left wheels

Applications

Two-seater electric commuters and one-seater electric minicars
