Wheel motors

Definition

Wheel motors are electric motors that are specifically integrated into the wheels of a vehicle, allowing for direct drive and control of wheel movement. This design enhances vehicle efficiency by reducing energy loss typically associated with traditional drive systems, improving acceleration and maneuverability. They are commonly used in robotics, electric vehicles, and automated systems where compactness and power efficiency are essential.
