A wheel motor is an electric motor located within a wheel hub or directly integrated with it. It represents a revolutionary innovation in the field of electric vehicles, as it eliminates the need for a traditional drivetrain. Wheel motors provide several benefits, including more efficient use of energy, reduced noise, greater design flexibility, and improved performance. Since the motor is directly coupled to the wheel, the torque is transmitted instantaneously and with more precision. This allows for better handling and increased traction, even in slippery conditions. Moreover, since the motor can be placed in any of the wheels, it enables torque vectoring, a feature that improves cornering, stability, and safety. Wheel motors are already being used in various applications, such as electric bicycles, cars, buses, and trains, and are expected to become more widespread in the future.
