Electric motors deliver jaw-dropping torque previously unimaginable by internal combustion engine engineers, and one electric ...

Despite the wide range of motor options available today, electric motors typically work based on the magnetic effect of current: an electric current flowing through a wire coil in a magnetic field ...

Each wheel or pair of wheels is powered directly by an electric motor. Torque distribution is fully controlled by electronics. A third type of 4WD is found in some hybrid cars. Here, the internal ...

Need a powerful electric motor on the cheap ... Some of the nuggets we get are the linear relationship of torque to current (10-15A max) and speed to voltage (12-15V DC) on these units, and ...

Robert Sansone is the winner of the 2022 Regeneron International Science and Engineering Fair for his research on high-torque, magnet-free electric motors. The innovative design could make EVs ...
