Hoofdmotor

Hoofdmotor is a term used in Dutch engineering to denote the main motor—the principal power source in a system or vehicle. In English, it is typically translated as main motor or primary engine. The term distinguishes the primary propulsion unit from auxiliary or secondary motors.

In automotive and electric powertrain contexts, the hoofd motor is the traction motor or main internal combustion engine that provides the majority of drive power. In hybrid or multi-motor configurations, the hoofd motor may be complemented by secondary motors that support specific functions, such as additional torque, speed shaping, or redundancy. In industrial machinery and robotics, the hoofd motor drives the main moving axis or subsystem, while other actuators handle secondary tasks or feedback control.

Characteristics commonly associated with the hoofd motor include high torque at low speed, compatibility with a transmission or gear reducer, and integration with cooling and power-management systems. Control software coordinates the hoofd motor with sensors and safety interlocks to optimize efficiency and performance.

The term’s usage is most common in Dutch-language technical literature and translations; in English-speaking contexts, main motor or primary engine is often preferred. See also main drive, traction motor, propulsion system, primary mover.
