Wheel Motor
By combining superior technology with its vehicle application knowledge,
Very few companies can claim to have 20 years of experience in the motor wheel field. You can trust
TM4 Transport's compact motor-wheel allows packaging flexibility by eliminating the central drive motor and the associated transmission and driveline components in vehicles, including the transmission, the differential, the universal joints and the drive shaft.

The motor wheel uses a brushless inverted rotor configuration that can be embedded inside a regular-size wheel. TM4 Transport's basic motor technology results in a light, compact and highly efficient unit. The power converters can be installed either inside or outside of the wheels. This system permits high-precision control and independent torque applied to each wheel while maximizing regenerative braking capacity.
